4 years ago The file ubootEnvtFileNandFlash.bin can be generated from a text source file using the command "mkenvimage -s 0x20000 -r". I manually generated it from the attached text file.
What I want to do is edit the uboot environment parameters.
First, I can't flash the nand with Ubuntu 18.04.3 LTS:

I can flash the image files from windows but so far I haven't discovered the magic to create the file ubootEnvtFileNandFlash.bin. The file uboot.env is created in a mmc build but not in a nand flash build. I looked at the two ubootEnvtFileNandFlash.bin files that I have. However, they don't seem to be standard uboot environment files.
How are they generated?
It may be flash_board generates the default uboot environments...
