Reading the AT91 related thread I digged a bit and maybe I found something strange between u-boot-1.1.2 and 1.1.3 ?

I usually use u-boot-1.1.2 using the "usual Atmel procedure"(TM) I removed T159 and booted, loading loader.bin in ram with xmodem, then it asked for the next file u-boot.bin that has been succesfully loaded. If I use u-boot-1.1.2 all is OK as with preinstalled 0.3.2

This is the result of my tests: Board AT91RM9200DK Kernel 2.6.13.2 u-boot always configured and compiled "as is" for at91rm9200dk

u-boot-1.1.2 ------------ - running in ram : OK - stored in flash with boot.bin as pre-loader and then u-boot as bootloader : OK - stored in flash as unique bootloader : DOES NOT BOOT

u-boot-1.1.3 ------------ - running in ram : DOES NOT BOOT - stored in flash with boot.bin as pre-loader and then u-boot as bootloader : DOES NOT BOOT - stored in flash as unique bootloader : OK BUT FAILS KERNEL UNCOMPRESSION

P.S. Looking into boot.bin sources seems that it required for Master clock, PLL frequency and SDRAM very low level settings.

Hoping this could be useful :-)
