No idea what "CM" is here, but that's not relevant here anyway. > Primary partition mounted OK > Loading file 'dtb/at91sam9g25ek.dtb' to addr 0x21000000 with size 25836 > (0x000064ec)... > Done > DTB file loaded OK > Loading file 'kernel/uImage' to addr 0x22000000 with size 2968536 > (0x002d4bd8)... > UBIFS error (pid 0): ubifs_read_node: bad node type (255 but expected 1) > UBIFS error (pid 0): ubifs_read_node: bad node at LEB 215:0 UBIFS error (pid > 0): do_readpage: cannot read page 178 of inode 1244, error -22 Error reading > file 'kernel/uImage' > kernel/uImage not found! But this is not a Linux issue if its U-boot which is failing to load the kernel. Are you sure you didn't upgrade u-boot at the same time as your kernel ? > If I will do ubifscat kernel/uImage it starts to read the file and then I see > this error: > > P?@ ???P?@ ???P?@ ??Q?? ?

That's not an error :-) It's the contents of the bootstrap code in the kernel that deals with very early issues such as decompression failures. You're just dumping your kernel image to the screen here.

Maybe your image is much larger than the previous one and a bug in the u-boot code used to load the image makes it randomly fail. Hoping this helps, Willy
