Hello all

I am making a RS232 - datalogger for my MasterThesis in the university.
My environment is
BDI2000 debugger
GNU toolchain
AT91RM9200

The work is simply to take input signals from the USART port and send
it to the SD card.
Can anyone please answer the following quesitons ?

1. I have u-boot running on my board. Is there a way to achieve my goal
by just using the u-boot. I am using FAT system on the SD card.
2. Is using Linux image a good idea. If yes . where can I find the
linux Image for my arm board ?
3. how can i debug u-boot using the BDI2000 ?
4. I used Windows Hyperterminal to download the basic Atmel examples
and it runs fine.. how can i use minicom to do it ? i configured it for
8N1 and xmodem /dev/ttyS0 but i dont see anyting which i could see
throh hyperterminal in windows
5. With the Atmel MCI sample code, i can recognise my SD card but
cannot save anyting .of course due to unavilaiblity of the FAT drivers.
How can i solve it ? 

Regards

Tutu

Atmel used to have a version of Linux configured to run on their
AT91RM9200 evaluation board, it was on the SDK CD.  They probably
still have it available on their web site somewhere, although I
couldn't find it just now with a quick search.

Contact Atmel's technical support.

the link inside this Atmel post doesnt work ! But there were other
stuffs which I could pick up ..such as minicom configuration !
Also, I am using parallel flash and most of the solutions were based on
DataFlash and that too only the kernel image is provided. I cant really
find the source code to  compile.

Well then,

http://www.at91.com
Then click the "Community Forum" link.
Then select the "Linux" forum.
Then select the "Announcement: Linux-2.4.27 package for AT91RM9200"

Instead of relying on an ancient 2.4 kernel (2.4.27 was released august
2004), you should get the latest 2.6 prepatch for which there's an AT91
specific patch at http://maxim.org.za/at91_26.html (currently 2.6.20-rc1).
A lot of AT91 patches were already merged into the mainline kernel, the
patches add fixes and enhancements that didn't make it into mainline yet.

You're not saying which board you're using - there might be some work
involved porting Linux over to your particular board.
