I'm running U-Boot 1.2.0 / (buildroot) 1559, and trying to test an app on the breakout-vx, so I'm constrained to using a tweener for console access and file transfer.
However, when I tried to run rz to accept a file, I find it's missing:
-sh: rz: not found
I suspect it has something to do with changes I made 6 months ago in menuconfig to pare down my kernel image. I don't see any direct reference to rz in the various menuconfig menus.
Can anyone help me figure out why rz is mising and how to recover it?
