i fix this issue with the help of all u-boot USERS, Thanks for helping .. This problem occurred because of u-boot.bin size taking 2 sector of Flash, and less space for Environment(few bytes in 2nd sector) . Then i incremented one sector in config env address , shown below. #define CFG_ENV_ADDR (CFG_MONITOR_BASE + 0x60000) // before CFG_MONITOR_BASE+0x40000
This help's me to solve this problem Thanks Rudresh Frank Svendsbøe wrote: > > Hi Norbert, > I just looked at your comment in the gmane archive. You shouldn't > hardcode a new CONFIG_ENV_ADDR.
