Hi everybody!

I'm building u-boot bin file to load into ARM9 single board ( Atmel AT91RM9200 ).

With default functions ( command ) of u-boot version 1.1.4, u-boot is loaded into my board and run correctly.

Note: I use u-boot-1.1.4-g7213859d.tar.bz2 downloaded from ftp://ftp.denx.de/pub/u-boot/, I also try u-boot source from git repository http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git

But when i add some functions for usb storage ( i want to boot my debian os in compact flash ), u-boot can't start.

some lines added in include/configs/at91rm9200dk.h

Then build u-boot.bin and load into. The terminal display :

######################################
1: Upload loader to Dataflash with vector 6 modification.
2: Upload u-boot to Dataflash.
3: Upload linux to Dataflash
4: Start U-boot
5: [nm] Identify Dataflash

[nm] dataflash_print_info :.id =

and stop here.... and I can't use u-boot.

Can you give me some suggestion. If possible, can you share me your u-boot.bin .

PS: I send you some attack files: one for my u-boot.bin ( can't start ), one for at91rm9200dk.h, one for my board picture. You check and give me some suggestion.

Thank you!
