So I have written in my application some code that:

1) takes an area equivalent in size to ENV_SIZE and places a series of
'\0' terminated strings
2) calculates the CRC32 and places it in the first 4 bytes

This is written to the NAND and used by U-Boot, no problems at all.

My application is GLP-3 and available at:
