Well, maybe that is the way to go.

I upgraded to the latest (head) version of u-boot. Now when I try to boot, I get stuck in malloc(). Anyone else see this?

Snipped...
Hit any key to stop autoboot:  0
switch to partitions #0, OK
mmc0 is current device

(System hangs, so let's see what's going on ...)

Reminds me of going back to step 1 in July 2019. :-)
