To: u-boot-users at lists.sourceforge.net

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<ftp://ftp.denx.de/pub/u-boot/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

/*#define CFG_DEVICE_DEREGISTER */
/*#define CONFIG_SUPPORT_VFAT*/
#define LITTLEENDIAN
#endif /* CONFIG_COMMANDS & CFG_CMD_USB*/



############################################################

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 =
DataFlash:AT45DB321
Dataflash read successful: Starting U-boot
######################################
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!

Your problem is that U-boot is linked to the wrong address (0).
Instead it should be linked to the position, where you intend to run
u-boot (in SDRAM)
I know Wolfgang Denx diesnt like the idea of running U.boot from RAM,
but you cannot run from an SPI flash, have to copy to RAM first,
and the SDRAM on AT91RM9200 is located at 0x20000000 and above.

The prinout you see, is not from U.boot.
It looks like a customized version of "dataflashboot.bin"
It "bombs" after dataflashboot.bin has loaded u-boot into SDRAM
and jumped to it starting point.

Since it is in the wrong locatgion, all the constant string pointers are
off, and really only points at '\0' characters, so any attempt to
printout data will fail.


You can get my u-boot at
ftp://at91dist:distib at ftp.atmel.fr/ in the "third Party" directory.

do:

make at91rm9200df_config

to get dataflash support.

This u-boot is based on the same source package, but with a number of
modifications, all not acceptable to Wolfgang...

If you are using Dataflash to store u-boot,
you can read this as well.

The Atmel web site is unfortunately a little dated.
The ftp://at91dist:distrib at ftp.atmel.fr/ has more updated dataflashboot in the Third Party Section
