16:50 <oldgalileo> Right now my thought was to change the sdmmc_boot partition group to include an SMD partition a-la-TX2, and then somehow read in from that partition in uboot to conditionally select the rootfs

16:51 <oldgalileo> I'm going to punt BUP stuff down the road, so my success criteria here is really just switching the rootfs from some metadata stored outside the rootfs in U-Boot.

16:51 <oldgalileo> Any thoughts would be amazing.

18:38 <oldgalileo> Just going to rubber duck a bit in here. If anyone wants to chime in, _please_ feel free.

18:39 <oldgalileo> It looks like the CBoot source has _never_ been released for the Nano. I'm pretty unclear on how I would even go about passing in arguments from UBoot to `extlinux`.

20:56 <oldgalileo> Just as a quick update, going insane. Can't get UBoot to display anything over serial. However the TX2 I have works just fine on the same carrier board on the J41 UART pinouts
