Try increasing CONFIG_SYS_MALLOC_LEN, e.g. to 4MiB. That fixed it for me on a different board.

It actually turned out to be something a lot simpler. Unlike Linux, u-boot only allows one active ubi partition. However, because it uses the code from Linux, when trying to access a file system you still need to specify which ubi partition it's on, which was neither intuitive nor obvious until I dug through the code.

When I specified "ubifsmount ubi0:recovery", it worked perfectly.

Thanks…
