Unable to Load or Run Files in Pycubed Board

[eap16]

I'm having issues running or loading programs in my Pycubed board. We soldered all the components onto the board ourselves, with the final board shown in the pictures below:

We ran the board in bootloader mode and uploaded the firmware and bootloader from the CircuitPython link (https://circuitpython.org/downloads?q=pycubed). It should be PyCubedv04 w/ MRAM, but we've also tried the other versions with no change in result. We're able to detect the board as a storage device in bootloader mode and flashing the firmware did cause the board to reset.

However, whether we're in bootloader mode or not, MuEditor is unable to detect the board. We're able to seemingly interface with the board when using CircuitPython's online editor when the board is in bootloader mode. We're able to save files to the board's storage device from the editor. However, running any code, even the example codes from the PyCubed website, creates no response from the board (not even a print line). Also, when the board turns off or reset, any files we tried saving into the board disappears.

Could anyone help in determining what the issue is? Why are we not able to connect to the board with MuEditor, or run/save any files?

It looks like you re-layed out the board. Did you make any changes to the schematic?

You might try removing R42 to disable the watchdog timer while debugging.
