ESP32-P4 SDIOIO: Unable to create sdioio object

[RetiredWizard]

CircuitPython version

Adafruit CircuitPython 9.2.0-beta.0-8-g340cc6328c on 2024-09-20; ESP32-P4-Function-EV with ESP32P4

Code/REPL

import board, sdioio
sd = sdioio.SDCard(clock=board.IO43,command=board.IO44,data=[board.IO39],frequency=20000000)

Behavior

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: SDIO Init Error 107

Description

This is the same message that occurs when "slot 0" is used as the default slot on an esp32-s3. The sdioio module should be defaulting to slot 1, but slot 0 isn't actually supported on the P4 yet. I'll build a debug image and confirm the slot that's being used and see if I can spot any other possible issues.

Additional information

No response

I wired up an external SDIO breakout and was able to mount the card using both SDIO and SPI interfaces so SDIOIO is working on the ESP32-P4 and I apparently either have an incorrect pin selection for the built-in SD card, or a hardware issue with my board.
