Unlikely. It looks like your user space needs 2MB per shell (order 9
allocation). Since you have only 5.5MB free, that may explain the allocation
failure (if init is forking another shell especially).

For the second core not coming up, an IPI needs to be sent to the non-boot core
to wake it up. A Kendryte thing. U-boot should probably do it before jumping to
the kernel. I thought I had that in the kernel though. Will check again.
