Hi,
I found an interesting situation where I can not decide whether it is a bug or functionality that should not be included at all.
If I generate UBI image consisting of 3 Volumes to NAND flash on my board, U-boot does not attach UBI to MTD. This happens only if UBI contains a volume that has auto-resize flag set. U-boot tries to resize it but fails.
Just started fixing it, but I have a question. Is it desirable that U-boot changes something in the FS? Would it not be better if U-boot would just read things out (that is all I want, to get uImage and dtb file) and leave the rest to Linux. (Linux handles the procedure without any issues).
Any opinion welcome.
