I have a situation whereby u-boot is not halting when key presses are made.
I have two TK1 modules - an old V1.0B module and a V1.1A module. The older module is with a customer and the newer module is on my desk. The older module is the one with the issue whereas the newer module is working fine.
Both have been previously updated with u-boot:
U-Boot 2016.11-2.7.2+g60021a4 (Apr 10 2017 - 07:55:49 +0200)
The very odd thing is, that when the V1.0B module boots through to Ubuntu, the key presses are accepted (although there are issues with the login not working, “authentication failure”) but fundamentally, it works.
Is there anything fundamentally different about this version of u-boot which would not work on the TK1 V1.0B?
