Hi Ti
I set some uboot environment variables like "boot_fit, bootfile, fit_bootfile, run_fit", and they can be set and saved over uboot command.
but if they were modified in uboot source code (uboot-phytec/include/configs/ti_armv7_common.h), compiling，and flash uboot partition, I found
they were not modified.
so How to modify these environment variables over changing uboot source instead of uboot command line?
could anyone help in this
Thanks a lot.
