Hello,
I'd like to report that H64 Model B pins theoretically responsible for TTL console (6, 8, 10) don't send any expected signal. I tested it on a few copys of the device and on every is the same. I also checked an adapter on Rock64 and there everything is fine, so it's H64 problem.
The listening during SBC launch is set to 1.5 Mbps (same as in Rock64 case), an oscilloscope detecting only simple periodic '1' signal on TX.
Thanks for help and best regards!
