Dear all, I was using u-boot-1.3.4 all these days . i decide to shift to new u-boot so that i can use some new features . i compiled the latest u-boot-2009.11.1 .but my board doesnt boot at all . My board is based on AT91SAM9261EK. i did a couple of changes to u-boot which i'm listing below 1) In the config file /include/configs/at91sam9261ek.h i changed the line #define PHYS_SDRAM_SIZE 0x04000000 /* 64 megs */ to #define PHYS_SDRAM_SIZE 0x08000000 /* 128 megs */ since i have 128MB SDRAM on my board.

and #define CONFIG_SYS_LOAD_ADDR 0x22000000 /* load address */ to #define CONFIG_SYS_LOAD_ADDR 0x27D00000 /* load address */ this is to reflect the change in bootstrap code to copy u-boot to higher address in SDRAM so tat RFS of size > 64MB can be copied . 3) and finally in the file /home/ravikulkarni/denx/u-boot-2009.11.1/board/atmel/at91sam9261ek/config.mk i modified TEXT_BASE=0x23f00000 to TEXT_BASE=0x27D00000 to reflect the change made for load address of u-boot in SDRAM when i did the above changes it works for me in u-boot-1.3.4 but when i do the same u-boot-2009.11.1 it doesnt :( . so may i know is ther any other new thing in new u-boot which im missing? thanks. warm regards, Ravi kulkarni.
