[OpenWrt-Devel] newer mikrotik boards not booting?

Anyone else seeing this on recently purchased  Mikrotik models?
Installing openwrt 19.07.03 on a Mikrotik LHG 5 boots, initfs and
appears to succeed with sysupgrade.  Then the device is in an infinite
boot loop.   It appears there's no console configured in routerboot to
see what it is doing.  Any pointers to turn on?

Note, I'm working with another individual seeing this on a new LHG 5
model device.  I have reproduced and tested on a newly purchased SXTsq
5HPnD, which has a motherboard labeled "LHG 5HPnD".   Prior SXTsq
5HPnD  and LHG 5HPnD models  have been working fine.

No baud-rate options?
