    - ActiveSync and USB client - Moble 5.0 vs. Pocket PC 2003 Hi, I'm trying to rewrite an application from Pocket PC 2003 to Mobile 5 that uses USB to ActiveSync. There are been some major differences. . . For PocketPC based PDAs (Compaq 3*, HP 55*, ASUS MyPal) we used a driver that offers serial communication via USB. It is found in the registry on [HKEY_LOCAL_MACHINE/Drivers/BuiltIn/USB] and referred to in [HKEY_LOCAL_MACHINE/Drivers/Active] which shows if the driver is activated. The driver is in the file bvd_udc_ser.dll In Mobile 5 the driver used by ActiveSync is in [HKEY_LOCAL_MACHINE/Drivers/BuiltIn/usbfndrv], which means that it is not a pure "stream driver" (with the pre-fix COM). This is a problem for us since the Pocket PC driver is deleted. The driver "usbfndrv" is visible in [HKEY_LOCAL_MACHINE/Drivers/Active] in the registry We hope that it is possible to activate the driver [HKEY_LOCAL_MACHINE/Drivers/USB/FunctionDrivers/Serial_Class] that is in Mobile 5. The problem it that it does not seem to be in the platform build. (since it is not in [HKEY_LOCAL_MACHINE/Drivers/BuiltIn]). The dll that it wants to use is named "serialusbfn.dll" but we do not know if it is in the OS-build. Where can we find "serialusbfn.dll" and do we have to deactivate "usbfndrv" (there is OS call)? Or, can we use the "usbfndrv" API directly to build something like a "stream driver"? Best regards, /hf Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76359

    - BIOS Bootloader Freeze Hello All, I'm attempting to use the x86 Bios Bootloader to load my nk.bin release image from my target system's hard drive. I've partitioned a 502MB primary partition on the hard drive, I've used mkdisk.bat to set up the bootsector, and I have copied and configured boot.ini and nk.bin. However, although the WinCE splash screen loads on boot, the system appears to freeze at that point. I've copied in the stream of error and warning codes which I receive from the serial port at the bottom of this message. I am aware that this is not a new issue; I have seen numerous reports of the same stream of error codes on this newsgroup and on other groups as well. However, I have not seen any postings indicating solutions which worked. A number of people suggested that the problem is rooted in bugs in the bootloader; if so, has anyone successfully built an alternative bootloader which they can share? In any case, my debug output is the following: INFO: code=0x4 // File found INFO: code=0x4 // File found INFO: code=0x4 // File found WARNING: code=0x05 // Unable to reset disk controller ERROR: code=0x1 // Unknown file system ERROR: code=0xD // Failed to read data from storage ERROR: code=0xB // Cannot read record information INFO: code=0x37 // Trying backup image file ERROR: code=0x1 // Unknown file system ERROR: code=0x3 // Couldn't read root directory sector ERROR: code=0x8 // Failed to load BIN image Sincerely, Avi Shmidman ashmid@actcom.co.il Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76353

    - Adding support for NIC cards on cepc Hello all, I'm trying to build a CEPC with a dell dimension 3000. The system has integrated ethernet (Intel Fast ethernet...), and i know from looking around that the intel cards are not ususally compatible. I did find that Intel has released wince drivers for the NIC hardware, but for the life of me can't figure out how to make it work with loadcepc and eboot.bin. There are references in the documentation on adding NIC hardware/vendor IDs to the eboot "table", but the doc is for ce 4.2, and I am using 5.0 (and the process looks like it's changed). Everytime I try to boot the CEPC so I can download an image I get the serial debug error about no supported NIC devices (even though it finds the integrated HW). I guess what I want to know is.. 1) is there a way to add unrecognized NIC device to the Eboot.bin loader that is used with LOADCEPC? 2) Is the driver provided by Intel only for use as "product ethernet" and not as the debug/download system (and to do this do I just add the driver to a cloned copy of the CEPC BSP)? 3) Am I completely insane and should just go use embedded linux? Any help/insight would be greatly appreciated! -Ian Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76350

    - CE 5.0 Q3 2005 QFE doesn't include needed USB 2.0 fix I am experiencing a problem with my USB mass storage device being dropped by the CE 5.0 host. I posted this problem recently, and Mr. David Liao from Microsoft responded : >>>>>>>>>>>> Did you get latest QFE on USB EHCI drivers? Recently, we did fix somthing like this. >>>>>>>>>>>> I see that the Q3 QFE for CE 5.0 is now released, but there is no mention of the fixes to ...drivers/usb/hcd/usb20/ehci/CPipe.cpp., CPipe.h, and trans.cpp. I attempted to install the code modifications in Mr. Liao's post, but was unsuccessful in achieving any USB functionaly at all after making the code changes. Where can I find the QFE that he refers to? I am an OEM Embedded Partner, should I be asking somewhere else? If so, where?

    - USB Problem with CE 5.0 Hi, I'm working on a CEPC platform for a Panel PC based on an SBC83675 board. The board has a Celeron 1.2 gHz processor and uses the VIA VT8606 "Twister-T" chipset. It provides two USB 1.1 ports. I started with the Industrial Controller platform and added the features I needed from there. Should it be possible to use a USB 2.0 compact flash reader with this configuration? I can plug a USB 1.1 compact flash reader into the system with no difficulties. However, if I plug in a USB 2.0 compact flash reader, it is not recognized. Debug messages show that the connection process gets to the point where the Usbdisk6.dll is loaded but the process fails shortly after that. The first significant debug message is: BOT_DataTransfer warning(6.7.2.3, RequestLength:8 TransferLength:4 Err:0 UsbErr:0x0, dwTimeout:5000) Up until the failure occurs, the debug messages from inserting the 2.0 device match the debug messages generated by inserting the 1.1 device. If I boot the system to MSDOS, it recognizes the USB 2.0 reader properly. I've searched through the archives and haven't found anything that has improved the situation Thanks, Jim Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76346

    - WINCE 5.0 CETK fails: internal clientside error Dear Gurus, When I run a OAL Timer Test, the CETK server disconnected abnormally and I get the message below: Posting WM_NETCONNECT(FALSE) message, ErrorCode = 631(0x277) AUTORAS:: Dialer notifies: [2] [Dialer Terminate] Internal Clientside error while trying to reconnect to the server. Clientside will now exit I tried many times, it always occurs on case 121, RTC Latency/Resolution (high priority) I dig into WINCE500/Private/Test/PQOAL/Timers/timerabstraction.cpp, and find that the test thread are running at priority 1, and set the thread quantum to 0. That says, it will never be swapped out unless it is blocked. So I guess the Ethernet thread must be waiting for the end of the test thread and can not respond for the CETK server, is that true?

    - btscosnd error Hi, I am trying to modify audio gateway codes to comply the handsfree profile. So I move some audio gateway functions into a application and try to run it in application level. In far, the acl connection seems to be ok, but the establishment of sco link fails. After I call OpenAudioChannel, the btscosnd driver try to establish a sco link by calling the InitSco (). In the debug output, the part of reading the device voice setting succeed, but the part of writing device voice setting failed. The error is BT_ERROR_COMMAND_DISALLOWED ( in StatusToError (), it is translated to system error ERROR_CALL_NOT_IMPLEMENTED). If I skip the voice setting writting, it fails in EstablishScoConnection. The debug output is BTSCOSND:: [ERROR] "Call UCT_CONNECT failed 1450" BTSCOSND:: [ERROR] "EstablishScoConnection FAILED 1450" Does anyone knows that if the voice setting writting must be executed? What is the possible reason of the fail of the sco link establishment? Any suggestions would be appreciated. Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76325

    - Serial image download failure Hello, The problem in a nutshell is that the Kernel Debugger in PB 5.0 immediately disconnects after each serial connection attempt to our x86 derivitive device (which does not have an NE2000 compatable ethernet chipset): "The Kernel Debugger is waiting to connect with target. The Kernel Debugger has been disconnected successfully." First of all, the PB target device connectivity options are set as following: Serial download and transport set to 115200/8/n/n/1 on COM 2 (I've tried hardware handshaking as well to no avail) I rang the cable out, it excatly matches the NULL modem cable architecture as given in the PB help. This cable is known to have worked with ActiveSync. The debug text coming out of sboot.bin (via COM1 on the device): "Sending boot request... Waiting for boot ack... failed to receive header signature failed to receive header" If use a terminal program to look at the data coming into COM2 on the PC (out of COM2 on the device), at 115200/8/n/n/1, it looks like: "kITL=BB$CEPC" This seems like a problem in my installation of PB, where it's just not responding to the request from the device. I've done plenty of searching in this group, but to no avail. Any thoughts? Thank you,=20 - Paul Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76307

    - What is Winsock error code 11010? Hello, I'm the same guy who asked all those NDISUIO questions. I seem to have gotten some of it working. When I try to send regular traffic through a configured WLAN interface, I get Winsock error 11010. The last Winsock error code is 11004. The descriptions continue on the page as "OS dependent" error codes (I guess CE is an OS dependency). Counting up from 11004, the one that corresponds to 11010 is "Overlapped operation aborted", which rings a bell given that CE doesn't support overlapped operations, but I was not attempting an overlapped operation.

    - re: PB (WinCE5.0) not hitting the break points It sounds like your symbols are wrong. I think sometimes if you rebuild while the debugger is connected, the debugger can lock the PDB file so that it's not rebuilt when your exe/dll is. Try rebuilding your module when not connected to the debugger. (I use shift-F5 to disconnect sometimes, and F5 to reconnect.) The other possibility -- if the modules are in ROM, and you did not re-make your image after rebuilding them, then there are different modules in ROM than you have PDB files for in your release directory. (Usually in that case the debugger will pop up a warning that symbols don't match the binary, but if you tell PB to permanently dismiss that warning you may not be seeing it.) If that is the problem, then remaking the image should fix your problem. You can also take a look at this blog post to see how to determine if your symbols are correct. http://blogs.msdn.com/kitlfirst/archive/2005/02/22/377629.aspx Sue sloh@microsoft.com (remove "online" from reply-to address) Now writing to a different blog! http://blogs.msdn.com/ce_base/ _____________________________________________________________ This posting is provided "AS IS" with no warranties, and confers no rights. _____________________________________________________________ Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76229

    - fscanf, sscanf performance hit under CE5 Hi folks, After doing some profiling and benchmarking, we've found something odd in the performance of the stdioa [fs]scanf routines in Windows CE 5.0 vs. 4.2. With a huge test file (50,000 lines, 3 tokens per line), under 4.2 and 5.0 both it takes about 2 seconds to just chunk my way through it with CreateFile / ReadFile (all these tests are just throwing away the data, there's no processing time involved). It takes a little over half a second to fgets() it one line at a time. But if I either work directly through it with fscanf() or read it a line at a time with fgets() and use sscanf() on that line, on 4.2 it takes about 4.5 to 5 seconds, while on 5.0 it takes _16_ seconds! And, of course, our standard (and large, and complex <g>) application is heavy on fscanf usage... :) Has anybody seen similar behavior from these or other stdioa crt functions? Can anyone explain what's going on that's causing such a performance hit? FWIW, here are a couple of sample runs (they are representative, I've got many similar runs): WinCE 4.2: Readfile took 2386 ms fread took 622 ms fgets took 711 ms fscanf(s) took 5075 ms (fgets took 854 ms and sscanf took 4520 ms) WinCE 5.0: Readfile took 2197 ms fread took 570 ms fgets took 646 ms fscanf(s) took 15991 ms (fgets took 777 ms and sscanf (%d) took 15398 ms) (fgets took 1530 ms and sscanf (%s) took 17289 ms) Thanks, -- Brian Bender Vocollect, Inc.

    - MMC/SD Interface Mode Setting Hello, The SDCard driver seems to support two different interface modes: SD_INTERFACE_SD_MMC_1BIT and SD_INTERFACE_SD_4BIT. The fourth bit interface is faster but only compatible with SD cards and not with MMC cards. The question is: Does the SDcard driver do the automatic selection of the interface mode based on automatic detection of the card capabilities, or it's necessary to call SDSetCardFeature, or modify a registry setting, to set the proper interface mode?

    - PB (WinCE5.0) not hitting the break points Hello all, I have set a few break points in my code. I'm using PB for WinCE5.0. I download the code via ethernet (its not the cross over connection). I observe debug messages in the PB debug window. I use a serial cable connnection for this. I'm running the debug version of CE. I've verified that I'm executing from RAM, break points are enabled, the code where the break points are set is actually executing. But PB is not stopping at the break points. All was well till a few days ago. I was happily setting break points and PB was stopping at all of them. One day I gave a sysgen and after that this behaviour started. Appreciate any help on this.

    - Locking data Hi, Can anyone provide insights on locking data in Windows CE similar concept to that of HDLock that is able to lock access to the laptop even then it was stolen for data security reasons. The following is an excerpt from HDLock, " Based on two-factor authentication and the government-standard 128-bit advanced encryption algorithm, HDLockT uses a USB A-Key®, along with a personal password, to act as the key to the notebook. The hard drive remains encrypted and inaccessible at system boot up, hibernation or shut down to anyone but the owner of the unique A-Key® and password. HDLockT is essential for businesses that want to protect that sensitive personal and corporate data that may be vulnerable to copy, removal or modification if a user's notebook is lost, stolen or left unattended." thanks, lois Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76171

    - oo16550 highspeed I see references to the highspeed serial buffering (isr16550) and I understand how it works. The docs say you can use it (link it) with the ser16550 driver. Is this also available/included for the oo16550? Is the high speed ISR in there by default? I looked at the code and can't tell. The sources for the oo16550 lib does have an include referance that points to the isr16550 directory. If not can I link it in? do I need to specify the two new registry entries (isrdll and isrhandler)? my sources uses: SOURCELIBS= \ $(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\com_mdd2.lib \ $(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\oo16550.lib \ $(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\serpddcm.lib Does this mean my seral is not as good (fast) as it could be?

    - Access to NDIS Intermediate Driver from user application Hello, We have an NDIS intermediate driver developed for Windows NT. This NDIS IM intercepts packets and sends it to another module for packet processing. The communication between the NDIS IM and packet processing module takes place using callbacks. The user application communicates with the NDIS IM using Device Objects. We need to port the NDIS IM to Windows CE 4.2. How should we go about replacing the device objects in Windows CE? Should we expose a stream driver interface in the NDIS IM or is there any other better way of accomplishing this? Please help!

    - CE5.0 TV-style navigation bug? Dear Sir, If my platform with TV-style navigation component when "iesample" or "iesimple" open some web page like http://tw.yahoo.com the mouse can not click any hyper link on it (cursor shape always arrow but hand). If that happened then only keyboard arrow keys and enter key work (move the yellow frame and execute). If I get rid off the TV-style navigation component from my platform then mouse action become normal again. Why? I found if my web page include this description then the problem will happen: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> But some of my page with frameset but not include the description above still met the same problem.

    - MiniportSetInformation and MiniportHandleInterrupt() are serialize Dear, I have an issue of NDIS driver on CE 5.0. My driver needs to wait interrupt from MiniportSetInformation. But, if MiniportISR() is called and it defers packets to let MiniportHandleInterrupt() do rest of works, while MiniportSetInformation() is executing, MiniportHandleInterrupt() is defered until end of MiniportSetInformation(). So, it makes dead-lock that MiniportSetInformation() is waiting interrupt but MiniportISR() is not called until end of MiniportSetInformation(). Did I miss something? Thanks in advance, Woojung Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76154

    - How to debug an exception Hi, I have a bug in my driver which results in an Undefined instruction exception AKY=00000049 PC=02ea26c0 RA=02ea2614 BVA=08140690 FSR=000000f5 What does the FSR mean? The instruction at the PC address is 02ea26c0 E59F3060 ldr r3,[pc,#0x60] which seems valid instruction When these come up i was wondering which are the key addresses to look at to find out what is causing it. I'm using PXA255 with WinCE V5.0. Thanks Tag: Geode, ATAPI, DMA and Windows CE 5.0 Tag: 76153

Hello,

I read a lot of articles about the GEODE ATAPI DMA problems under Windows CE
4.2. Because of the fact it did not work properly for me I had turned off
the DMA feature (Using the SETTINGS registrykey). Now I have created my first
Windows CE 5.0 image for my GEODE platform. If I enable the DMA mode, my
Windows CE image boots without any problems. But sometimes it happens that
file writting or reading creates an error. So my first thought was: DMA
troubles.

These are my settings:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Template\GeodeIDE]

Can somebody help?
