Hello all

I'm trying to compile and boot version 1.1.4 of u-boot but after i compile succesfully
and download to the target (at91rm9200-ek not dk) the atmel boot loader reports:

PLLA set to 180MHz MCK set to 60 Mhz, loads uboot to sdram (0x21f00000) and the u-boot crashes. Are there any settings needed to be changed in at91rm9200dk.h?
what can be their possible values?

thanks in advance

I'm trying the same.
I've compile and download u-boot successfully.
The very first restart is successfull too.

But when I do
saveenv

and then reset u-boot does not find the RAM

after reflash the bootloader (u-boot.bin) everything is ok.

What can I do?

u-boot 1.1.0? I'm using this currently to boot my linux system from a serial dataflash

I just can't compile u-boot 1.1.4 (as well as 1.1.2 and 1.1.3) so as to load from serial dataflash. The default is to load from the parallel flash. I need some kind of patch (like the one provided by atmel for u-boot 1.1.0) for 1.1.4 as well. Is there one?

For you Manuel it seems that when you setenv (and u-boot tries to save the enviroment to the parallel or serial dataflash) it cant access the storage space and thus it crashes. Find in u-boot-src-root/include/configs/at91rm9200dk.h the sections regarding the various flash memories and fix any inconsistencies (invalid start addresses is usual, as well as using the serial dataflash rather the parallel)

What you can also do is put some entry of the type

#define CONFIG_SERVERIP 192.168.100.1

in the same header file. This will be loaded as enviroment variable from u-boot at startup, so you will not need to setenv

cya
