I tried it with the rshell, the same problem.

MicroPython v1.18-5-g037b2c72a-dirty on 2022-01-19; Raspberry Pi Pico with RP2040
Type "help()" for more information.
>>> import testUART2.py

No response at all.

So you did the wiring, and the patch wires ate fine?

Since you use an own build: did you try a firmware from the download page?
