Board: Pico2
I followed the steps in the readme and had micropython working at one point; however, after turning the device off and later turning it on, the micropython prompt did not come up. The backlight of the screen still came on (and the screen appears to be fine - I've tested flashing the PicoMite firmware onto it, and the screen works properly with that) but now, no matter what version of micropython firmware I try to flash, nothing comes up when I turn the PicoCalc on.
I've tried flashing with:
picocalc_micropython_NOfilesystem_pico2.uf2
picocalc_micropython_withfilesystem_pico2.uf2
picocalc_micropython_ulab_eigenmath_NOfilesystem_pico2.uf2
picocalc_micropython_ulab_eigenmath_withfilesystem_pico2.uf2
And I have copied boot.py, main.py, the examples folder and its contents to the Pico2 after flashing, when necessary.
I have noticed that Thonny reports the following in the shell after connecting:
Traceback (most recent call last):
File "boot.py", line 13, in <module>
File "picocalc.py", line 144, in __init__
File "picocalc.py", line 195, in reset
File "picocalc.py", line 153, in write_cmd
OSError: [Errno 5] EIO
...which has me worried something is faulty with the pico2 or the picocalc board, as from what I've been able to find EIO errors are something to do with i2c stuff. But apaprently having the cable connected to the Pico2 interferes with picking up the keyboard (noticed that in PicoMite), so I have no idea.
Do you have any ideas what could be happening?
