Linux/AM3517: u-boot cannot read the env variables from NAND and fails with error code -74

Part Number:AM3517

Tool/software: Linux

Hello,

I am using am3517 for our product. I have used the MLO and U-boot provided in the kit to boot the device successfully using MMC.

I flashed the uenv.txt file through flash programming tool at location  0x260000 and tried rebooting to change my default uboot env values.

But the read from NAND failed with the following command.

*** Warning - readenv() failed, using default environment.

Please help me understand how to resolve this issue.

Thanks

Harish K
