    - Delay in VoIP call for WinCE5.0 device Hi All, We are developing a MainstoneII based VoIP handheld device, on WinCE 5.0 with PXA 270 processor. On making VoIP call we are getting delay of 3 seconds. What can be possible reasons for this, whether any driver like ethernet cotroller can cause a delay. We are using SMSC 9118 ethernet controller.Plz help me in this. Thanks in advance Jipin Tag: nand partition Tag: 112448

    - Win CE USB Mass Storage Class Driver Hello, We are using Win CE 5.0 USB host stack for the development purpose. We found that Win CE Host stack has a very low performance. We have done few modifications in the USB Mass Storage Class driver to enhance the speed of USB transfers in Host mode. WinCE Kernel USB Class Driver fixes - 1. Changed Max Transfer size from 8KB to 32KB. Result - Number of SCSI commands was reduced. 2. Removal of SCSI Test Unit Ready(TUR) Command during Read/Write operation. Result - Time taken by TUR Command is reduced during Read/Write operation. 3. WinCE Scatter-Gather Buffer changed from 8 to 128 (SG_MAX_BUF) Result - Disk I/O Delay is reduced by increasing the number of buffers Changes in MS WinCE Kernel system Memory 1. Memory Type changed to RAMdisk Result - RAMdisk access times are faster than WinCE system memory We need know, 1. Whether the above modifications will affect the stability of the Win CE kernel and system. 2. Will they have any detrimental affect on their internal kernel modules. Thanks in Advance, Sheeja Tag: nand partition Tag: 112435

    - Audio channels volume is inverted...? Recently we faced this problem: 1)the 'waveOutSetVolume' documentation states that 'The low-order word [of 'DWORD dwVolume' parameter] contains the left-channel volume setting, and the high-order word contains the right-channel setting'. 2)AC97 codec registers for volume(s) are 16 bit: the LSB is the attenuation for the right channel, while the MSB is the attenuation for the left channel (actually only 5 bits out of 8 are used). Let's take a look to the low-level function which sets the volume in %_WINCEROOT%\..\DRIVERS\WAVEDEV\UNIFIED\ENSONIQ (comments are mine): **************************************************** CDriverContext::SetVolume (ULONG ulVolume) m_ulVolume = ulVolume; /* The '&' keeps only the higher 5 bits due to the AC97 register format. Then we 'justify' the data to the right */ USHORT usLeft = (USHORT) ((m_ulVolume & 0x0000F800) >> 11); USHORT usRight = (USHORT) ((m_ulVolume & 0xF8000000) >> 27); /* Since AC97 volume register represents the attenuation (i.e. 0 dB == MAX_VOLUME), we subtract the volume from 0x1F */ usLeft = 31 - usLeft; usRight = 31 - usRight; /* Here we build up the value to write in the AC97 register: NOTE that we are putting the RIGHT volume in the higher part of the word when we should put the LEFT volume, and viceversa */ USHORT usRegVal = (usRight << 8) | usLeft; /* Write data to the codec */ m_pDevice->WriteCodecRegister(AC97_PCMOUT_VOL, usRegVal); **************************************************** All the other audio drivers I've seen in WINCE600 (and previous version of the OS), although with slightly different semantics, seem to make the same mistake... Am I wrong or missing something...? -- Luca Calligaris www.eurotech.it Tag: nand partition Tag: 112432

    - Serial Problem with USB I have the following problem with serial devices connected through USB. Situation: Windows CE 5.0 running on a PXA270. NET CF 2.0 (No SP) USB Devices connected through a USB HUB. 1 FTDI USB To Serial device. Other USB devices (Including serial devices, and Mass storage devices) Recognition of all the USB Devices work without problems. When i boot up with my FTDI Device attached, all works and i can open the serial port and communicate, But as soon as i attach an other Serial USB device the FTDI Serialport gives an error (I suspect the port gets closed). This only happens if i attach a Serial based device (A GPS Mouse, and Microsoft Wireless keyboard,mouse for example) the problem does not occur if i attach a Non Serial device like a Storage device. The problem also doesn't occur if i attach another FTDI Serial device. When i attach the Serial device and then bootup the device no problems occur aswell so the devices are all recognised, it's only the fact that if you attach the device after bootup, and when the other serialport has already been opened my problem occurs. For test purposes i removed all the drivers for the GPS Mouse in the registry, so whenever i attach the GPS Mouse it's not recognised as a valid device and displays the famous add driver dialog, but even then my serialport gives me an error although in theory i would think that nothing would happen. Could anyone shed some light on this issue. If you need more info about the settings in the registry i can post them, only didn't want to make this post to long Best Regards, mario Tag: nand partition Tag: 112429

    - Does CE 6.0 R2 new nandflash driver model support IOCTL_DISK_READ ?? hi,all, Firstly, my new nandflash driver seems working well, and I could access nand in device explorer by common file operation method. In one of my app,I need access nandflash by DeviceIoControl. But when I sent IOCTL_DISK_READ to nand store handle,it always complained invalid parameter.

    - USB Mass Storage-Usbmsfn.dll problem. Hi All, Right now my CE device is getting detected as a Mass Storage Device. I could see the drive as "USB Mass Storage Device D:" . But if i try to access, i could see only empty folder and when i view the properties, "Used Space" and "Free Space" are shown as 0 bytes. My platform USBFn driver is derived from pxa27x which is available in public folder. From my BSP platfrom i could get retail messages from pxa27x usbfn driver. But not from usbmsfn.dll which tells me that usbmsfn.dll is not at all getting loaded. I am not sure, what is causing usbmsfn.dll driver not to load? Please give me your inputs.

I need to find a vendor (software or hardware) to sell a Turn-by-Turn Mapping solution. The hardware platform is a X86 Windows CE platform. This platform is based on a CEPC, x86 platform. The volume of platform is about several hundreds device. So I hope, there is a vendor could sell a SDK, like map engine, GUI SDK implemented by C++ or .NET Compact Framework and run on the x86 Windows CE platform. So I could implement Turn-by-Turn mapping into or intergate the propritary product. Thanks Lu Tag: nand partition Tag: 112376

    - Error 4309 returned when writing files Hello, We have a WinCE 5.0 Core system running on a 1 Ghz x86 platform. The hard disk drive is set up as a CF card. Our program previously ran on WinCE 4.x with no problems, but now we repeatedly get errors when writing to the disk drive. GetLastError() returns 4309 (resource required). I suspect there is some security issue. We have the NoDefaultUser registry setting set to 0 by default. The platform was started from an internet appliance base and we have omitted all items we dont use in order to adhere to the core licensing agreement. We have no use for any "user" security. We need to be certain it is defeated, yet I haven't yet determine a successful solution. Any suggestions would be appreciated. Thanks, Ken Tag: nand partition Tag: 112361

    - IRQ_BULVERDE_MAX CE 6.0 Question Hey all, I am porting a 270 based platform from CE 5.0 to CE 6.0 and have found a discrepancy with the defined value of IRQ_BULVERDE_MAX between the two versions. In CE 5.0 it is defined as follows... #define IRQ_BULVERDE_MAX IRQ_RTCALARM ...where IRQ_RTCALARM = 31. In CE 6.0 it is defined as follows... #define IRQ_BULVERDE_MAX 63 //icmr (32) + icmr2 (32) Is there a reason this was changed? I am defining additional platform specific IRQ values based off of the IRQ_BULVERDE_MAX value, but this paradigm is broken in CE 6.0 because the OALIntrStaticTranslate() routine (common lib, map.c) is comparing against the OAL_INTR_IRQ_MAXIMUM value which is defined as 64 for both versions. What this causes is the IRQ translation in CE 6.0 to be skipped because the compare fails, which in turn causes the SYSINTR to be mapped to the IRQ init value of -1 and then breaks IRQ dependent drivers. Obviously, I can manage to work around the issue, but I just wanted to get the reasoning behind the change to IRQ_BULVERDE_MAX. Tag: nand partition Tag: 112350

    - Block device auto format prompt I have a problem which seems like it should be simple to solve but I can't work it out. I have developed a block device which is designed to store a file system on a file. This file can then be mounted and unmounted programatically to allow the user access to the filesystem. I've used the technique of using a dummy block device which bootstraps the normal FAT FSD, then the block device can be activated and deactived to bring the file system up and down. However the problem I has is that if the file has just been created it isn't formatted, so I need the option of being able to format it. I want a prompt to ask if the device should be formatted, then the user can decided to format or not to format. My registry keys are: [HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MyDisk] "Name"="MyDisk" "Folder"="MountedStorage" "AutoMount"=1 "AutoFormat"=1 "AutoPart"=0 "PartitionDriver"="" "DefaultFileSystem"="FATFS" [HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MyDisk\FATFS] "Flags"=4 Strangly it use to prompt me before formatting, but after I added the PartitionDriver entry to the registry the original auto format prompt stopped appearing. But without this key the disk was not being formatted correctly and the MBR/Sector 0 didn't appear to be correct. Previously I could set AutoFormat to 1 and the format was silent, or AutoFormat to 0 and the prompt appeared before mounting and formatting. Now all I get is a silent auto format, or nothing at all. This silent autoformat will cause a problem because the software on the PDA is designed to operate with an existing 2K/XP driver. If this file was created on the desktop and formatted as NTFS rather than FAT then clearly I don't just want the PDA to silently reformat the device and lose all the data. Another possibilty might be if I can programatically format the device. But I don't own the fsd driver so I don't know how to ask it to format the file system (e.g. using FSDMGR_FormatVolume), and I can't open the volume and use IOCTL_DISK_FORMAT_VOLUME or IOCTL_DISK_FORMAT_MEDIA because until it is formatted it won't mount so \MountedStorage\Vol: doesn't exist. Can anyone point of a solution to the auto format prompt, or tell me what I am missing with regard to a programatic format? Jamie Tag: nand partition Tag: 112306

Also I had a look in the PUBLIC\COMMON\OAK\LIB\ARMV4I folder and found that there are libs present correspondign to some components that have changed in the PRIVATE folder. I could not find all the libs corresponding to all the changed components. So, my question is, will it be fine if I do not install the PRIVATE source code? Is it OK if I get the updated libs in PUBLIC folder only and then build an image? What is the general procedure for including the PRIVATE folder source code into the NK.bin? I dont think the PRIVATE folder would be built ever, instead the corresponding libs from PUBLIC folder woulc be used. Right? - Varun Tag: nand partition Tag: 112299

    - What is the reason that trigger the "Network and Dial Up Connections UI"? My WINCE5 device always popped up a dialing dialog just a while after startup. The dialog is the "Network and Dial Up Connections UI". If I set following item in register: [HKEY_CURRENT_USER\ControlPanel\Comm] "AutoCnct"=dword:0 then the dialing dialog will not be showed, but another dialog popped up. The tilte is "communication error" ,and the dialog said that it can not start the communication with PC, and the error number is 608 ... The device did not show the dialog before, and I have not changed the components of OS for a long time. Yes ,there is IE component in the OS which is the dependency of .NET2 , but there is no network service should be started at startup, and I have installed all QFE . Any advice? Thanks.

    - Help with PartitionTable Hello, I have an x86 WinCE50 system that uses the ATAPI IDE driver for a system CF card. Currently, I have the CF card partitioned into 2 parts: *Partition1 = Fat16 bootable partition with CEPC Nk.bin *Partition2 = TFAT formatted partition for WinCE use. I am currently trying to mount the partition 2 as root, but having no luck at all. I have tried the following approaches. 1) Use MountAsRoot and AutoMount keys for partitions to set which should mount as root, making sure to set Part1 MountAsBootable=0 so it does not think system/hive files are on the drive. Result: Partition 1 still mounts to root. This seemed to have no effect. Maybe I am messing up the way I use the Profile? (HDProfile \Part00\ see my reg below)? 2) Use the 'cheating' method to set the PartitionTable key 0x04 to invalid FS. (suggested here: http://groups.google.com/group/microsoft.public.windowsce.platbuilder/browse_thread/thread/e122bf548aab3c7c/c61f11d3a810184f) [HKLM\System\StorageManager\PartitionTable] "04"="SYSBOOT" Result: Both partition 1 and 2 do not mount and the system halts after storage manager. To my understanding, the first partition formatted in FAT16 is 0x04. However, shouldn't my TFAT partition be type x0B (MS-DOS 32 bit FAT)? Perhaps I am wrong in my assumptions of how the PartitionTable works. 3) Setting the "PartitionDriverName" to blank in an attempt to load null partition driver [HKLM\System\StorageManager\Profiles\HDProfile\Part00] "PartitionDriverName"="" [HKLM\System\StorageManager\Profiles\HDProfile\Part01] "PartitionDriverName"="MSPART" Result: Both partitions still loaded.

    - CreateEvent and SetEvent in WinCE6.0 Hi, I am a newbie to Windows Embedded CE. Try to understand Embedded :) I have a wince 5.0 based Application which creates a unnamed event and sends an IOCTL to driver. Upon completion of requested IO, driver uses setevent on event handle passed by APP. The whole thing works fine on WinCE 5.0 Now I have this driver in wince6.0 for a different platform, when i run the APP (built using wince 5.0), i see exception "Abort data" in driver (setevent, driver built using wince 6.0) using unnamed events is not allowed in WinCE6.0? If so, is there a work around for this instead of using named events? Any information on this would be of great help --Thanks in advance Vikranth Tag: nand partition Tag: 112272

    - DDKReg_GetWindowInfo() returns ERROR_INVALID_PARAMETER Hi all, I have written a simple device driver that is loaded at boot time. The driver needs to read MemBase and MemLen from the registry when initialised. I use the pointer that I receive in XXX_Init( PVOID Context) to open the device key ( hnd = OpenDeviceKey( (LPCTSTR)Context ); ) and that seems to work. However, when I call DDKReg_GetWindowinfo() with the returned handle it returns ERROR_INVALID_PARAMETER. According to MSDN this "Indicates a problem with the populated DDKWINDOWINFO structure." What does this mean? My registry entry looks like this: [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GDU] "MemBase"=dword:40100000 "MemLen"=dword:40 "Prefix"="GDU" "Dll"="gdudev.dll" "Order"=dword:22 Any ideas are much appreciated.

    - Ethernet Throughput Too Slow for Wince 5.0 I am running wince 5.0 with an AMD AU1100 processor running at 396MHz. I am integrating a RTL8305SC ethernet switch within the hardware platform. I am currently getting around 16.5 Mbps throughput uploading a 40Meg file to a server, and 23.5Mbps downloading a file from a server. This seems extremely slow for WinCE 5.0. On the desktop I can get almost 80% of the 100MBps link speed. Is the ndis.dll driver at a low priority such that it is not able to buffer up packets and send them out faster than the current rate I am experiencing? How can I speed up the throughput?

    - SD card and File System in WinCE 5....? Hi all I am developing SD card driver (SD Host,SD Bus, SD Client), the SD Bus and SD Client Drivers are got from \PUBLIC\COMMON\OAK\DRIVERS\SDCARD\... Now ,I am facing a serial problem, and have no idea to solve it. The condition is: When system suspend and resume , we dont want unload and reload SD Cleint Driver,the reason is if the App is running and read/write data from/to SD card, we hope the App is keeping running, not broken by resume system.(Unload or reload will cause system to broadcast a device changed message, we dont want to get it) In SD host driver,my method is when system resume ,I call the function SDHCDIndicateSlotStateChange(m_pHCContext, 0, SlotResetRequest); And I do a test , that is "I do a file copy/paste by File Explore", but it always failed. I check the data of SD card, it is integrity and identical , nothing lose. And I do other test, that I execute a App(the App is a multimedia tool) to read/write data to SD. When reading/writing from/to SD card, I suspend and resume the system , the App is keeping playing. So I am confused, what happened to it? I really have no idea about it... Could some one help me? ... BRs Jack Tag: nand partition Tag: 112231

    - Emulator performances I am experiencing a big difference in performances between a Windows CE emulator image generated by me as part of an SDK and the emulator images provided with the Windows Mobile 6.0 SDK. To be more specific, the problem is related to the startup time of a .NET 2.0 application. The application loads many bitmaps at startup and has a startup time of around a minute in release and two or more minutes in debug on my emulator image. That startup time decreases a bit when I include in the image CF 3.5 instead of 2.0 (the application is still CF 2.0 based) bu it's still twice or more of the amount required to start the same application inside the WM6 emulator, provided with the Windows Mobile 6 SDK. The overral performances of the application inside the WM os image seem to be better than those on my own OS image, but the difference in startup times is quite noticeable. Both OS images use the same amount of memory inside the emulator (256MB) and the amount of free memory before the application is started is the same on both emulator instances and the application allocates the same amount of memory etc. Also the screen resolution is the same on both emulator istances (800x480). My OS image include the .NET framework dependencies, the standard shell and not much more. No services or other applications that may "eat" CPU time in background and no KITL or debugging support. I suppose that the WM6 image runs some more drivers in background (for phone emulation, at least) and that the WM shell is, at least, comparable to the standard shell in terms of CPU and memory usage. My OS image is based on CE 6, while the WM6 image is 5.something, but the new kernel should improve performances... and not having the limit of the 32MB slot may allow the .NET application to allocate more memory without requiring a garbage collector compacting operation, so I expect better performances on my OS image than on the WM6 emulator or, at least, the same level of performances... The application executable is installed in \Program Files so it's loaded from RAM on my OS image and does not access external data files etc. It loads some DLLs (most of them are .NET managed code and native code interaction is limited to some API calls). There are some "tweaks" that can be used to enhance device emulator performances? I used the device emulator BSP provide with CE 6 Platform Builder. There are other releases of that BSP available? Most of my customers still use CE 5, so I don't have a direct comparison of the same application running on the same device on the two OS releases. Someone else noticed big performance issues using the .NET framework on CE 6? -- Valter Minute www.fortechembeddedlabs.it Training, support and development for Windows CE (the reply address of this message is invalid) Tag: nand partition Tag: 112229

Hi,

You can use Boot part library at boot loader level and create
partition.
