Problem with IMGFLASH option of platform

Dear All:


The symptom I observed is that the performance of FTP server
upload/download. The platform builder version is 4.2.
And the processor is Intel DBPXA255(ARM).

I did some tests:
;----------------------------------------------------------------
A file (larger than 7MB).

if I set IMGFLASH=1 (from platform setting){
if I upload a file to \temp (object store){
the ftp server RX is about 900 KBytes/sec;
the ftp server RX is about 1500 KBytes/sec;
}

if I upload a file to \RAMDisk (Ramdisk){
the ftp server RX is about 900 KBytes/sec;
the ftp server RX is about 1500 KBytes/sec;
}
} else if I do not set IMGFLASH=1 {
if I upload a file to \temp (object store){
the ftp server RX is about 300 KBytes/sec;
the ftp server RX is about 500 KBytes/sec;
}
if I upload a file to \RAMDisk (Ramdisk){
the ftp server RX is about 300 KBytes/sec;
the ftp server RX is about 500 KBytes/sec;
}
}

It's always slower to execute from flash than from SDRAM. Accesses to SDRAM
memory are much faster than flash. You might look at your flash timings to
ensure that they are as optimized as possible. If you have burst or
synchronous flash, be sure to make use of those options.

Dear Sir:

I understand what you mensioned about is the flash/sdram speed problem,
and I know that flash XIP will slower than SDRAM.
But the point I can not understand is that since I built an nk.bin Image for
Flash, after the nk.exe boots, why it can only XIP rather than load the
whole OS image into SDRAM? Surely the IMGFLASH option unchecked will cause
the nk.bin download to the SDRAM directly, and there is no flash memory
issue.
The main question is that how could I make nk.exe know that I want to
load the whole OS image into the SDRAM rather than keep the OS image XIP in
flash?

Furthermore, if I do not use the eboot's "Program RAM image into FLASH"
option to write the RAM image to flash, the performance will be better.
If I use the eboot's "Program RAM image into FLASH" option to download the
RAM image into flash memory, the performance will be worse than the former,
could anyone tell me what's going on with the WinCE OS when loading itself
into the main memory? Is there any option to set about it?
Thank you very much.

Best Regards,
mjwang
