Hi, is there a tool to create an "environemnt image" that I can flash to my NAND?
tools/envcrc will output the binary env blob if you give it the --binary option. but it does not take arbitrary env inputs. ./tools/envcrc --binary > env.bin
I think I've seen a tool that takes a text file with an environment setting per line, calculates the CRC and generates a binary that can be transferred to the board (via tftp or other means) to be written with "nand write".
sounds like it might be a useful addition to tools/envcrc
Alternatively, is there a description of how the environment is read, my U-Boot, so that I can write my own program to create such image?
