Re: Seems I burnt my UART2; any alternative?
Forget it, my Core3566 is booting no more! https://ferryfair.com/md.html?files/notes/Core3566.md is the work I've done on it so far. I'm on verge of getting IMX219 and OV5647 cameras working on Linux-7. I'm gonna stop here. The Waveshare-IO-base-B is working fine with BPi CM4. Goodbye to Luckfox and ...

Seems I burnt my UART2; any alternative?
Core3566 mounted on Waveshare IO-base-b. Its GPIO header pins 8 and 10(tx and rx) are connected to rx0 and tx0 of ESP-WROOM-32D by mistake instead of connecting it to rx2 and tx2. From then on i can read no output on core3566 pin 8; i regularly use picocom at 1500000 baud rate to login. Is there ...
