Hello Submarine Friends!

My goal is to keep env at fat partition on mmc. I added these definitions to am335x_evm.h config.

#define CONFIG_ENV_IS_IN_FAT #define FAT_ENV_INTERFACE "mmc" #define FAT_ENV_DEVICE 0 #define FAT_ENV_PART 1 #define FAT_ENV_FILE "uEnv.txt"

Note that the uEnv.txt file is used for something similar but different, so please use a different name here.

This enables to store the content on MMC, but I am concerned about two things: 1)I got this warning message every booting: reading uEnv.txt FAT: Misaligned buffer address (8fa16f10)

Depending on where in the boot process that is, it could be that.

2. There is a problem with opening the file in text editors, because it have non ascii bytes at head.

But seems data is not corrupt.

Correct. With the environment stored as a file in FAT it is NOT also stored in plain text. You would need to use fw_printenv/setenv to modify it.
