Hello Michael,
I tried to use the MTD layer but that did not work even though I set the flash in the Linux device tree read-write. I cannot remember the output exactly as it is some time ago that I tried (with Debian).
Cheers, Bastian

Hi Bastian,
ok I see. I'm fine with this. But one remaining question. Why do you truncate to 384KiB? The upstream bootloader has its environment in the last sector, ie 448KiB.
