Greetings everybody..I am using u-boot1.1.5 for at91rm9200ek type board(arm).
U-Boot 1.1.5 is *old*. I suggest upgrading to the current version. Lot's of things got fixed here.
The flash memory used here is s29GL512N(128k sectors).I am able to configure the board/config flle properly it seems. The driver also erases/writes properly it seems. The problem is when I am trying to save environment variables it is getting set but in some cases after a reset it is showing Bad CRC and getting to the default environment. The other thing is I am not able to boot the kernel image from the flash due to some bad checksum error. Everywhere the problem is related to crc. I am a bit confused why the CRC check fails everytime? Is it not writing properly and if it is not writing properly then how it is able to get the u-boot prompt..
The required configurations defined
#define CFG_ENV_ADDR (CFG_FLASH_BASE + 0x20000) #define CFG_ENV_SIZE 0x2000 #define CFG_ENV_SECT_SIZE 0x20000 #define CFG_MALLOC_LEN (CFG_ENV_SIZE + 128*1024) #define CONFIG_STACKSIZE (32 * 1024)
The TEXT_BASE in config.mk :
TEXT_BASE 0x21F00000
Please help as soon as possible...
Debugging this problem in the old U-Boot version doesn't seem to make sense to me. Please try to upgrade.
Best regards, Stefan
