Ah! Here you can see that the CRC is incorrect in U-Boot already, so why do you expect to see a different result when using fw_printenv? WHen the CRC _is_ incorrect, both U-Boot and fw_printenv will report this fact in the same way. > *Print message after execution of saveenv command from uboot : > > *Saving Environment to dataflash... > copy 0xad030000-0xad040000 to saveenv-buf 0x80100000. > erasing 0xad030000 - 0xad03ffff > Erasing sectors 0x3 to 0x3 > sflash.c:69:DF_F_PageErase: erasing page: 0x3 > done erasingsflash.c:164:DF_F_DataFlashWrite: write: src 0x80100000, dst=20 > 0x30000, size 0x10000 I have no idea what sort of code you might be using there, there is no such file as 'sflash.c' in the mainline U-Boot code. And U-Boot 1.1.2 is old. I mean: OLD. Really, really OLD. Nearly 5 years old. Please consider it completely unsupported at this time. Please update and use recent code instead.
