My board is based on AT91SAM9261EK. i did a couple of changes to u-boot
which i'm listing below
- 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 .
- 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 To make the story short .. were the above changes correct for new u-boot? if not what changes i have to a) accomodate 128MB SDRAM instead of 64MB which comes with AT91SAM9261EK b) to copy RFS size > 64MB . any help from AT91 users ? warm regards, Ravi Kulkarni.
