I ported u-boot to my customized s3c2410 board. My board uses NOR flash SST39xF1601(2MB). Everything seems to be ok except it can't save environment variables using saveenv command.
Then your flash configuration does not match your hardware.
Would you tell me how to solve that issue? Thanks.
Fix your configuration.
I defined smdk2410.h about flash as belows:
This is not enough to make any statements, especially sinc we know nothing about your hardware.
#define CFG_ENV_SIZE 0x20000 /* Total Size of Environment Sector */
One formal comment: Your comment is wrong here. What you #define is the toal size of the environment, not the size of an environment sector. These *might* be the identical, but would be pure chance.
