RP2040 microSD fails

[mikeysklar]

I noticed an issue with RP2040 and microSD being a little off while testing the current main branch code yesterday.

Coming back to it today this is the problem.

Using the HX8357 3.5" Featherwing TFT.

Running the FeatherWingHX8357 example.

I'm able to access the microSD using two other boards, but not with a Feather RP2040.

RP2040 error (using main branch Adafruit_Imagereader)

Initializing filesystem...OK!
Loading adabot.bmp to screen...File not found.
Querying parrot.bmp image size...File not found.
Loading wales.bmp to canvas...File not found.

Same sketch / display / cord / microSD works fine on ESP32-V2 and M0. Images display as expected.

Just confirmed that a Feather RP2350 worked.

Current state:

Thinking that I might have cooked the Feather RP2040 I soldered headers on another one. Same issue.

Point of interest. The microSD error on RP2040 boards only wobbles between this error on soft reset.

Initializing filesystem...SD begin() failed

and this one on hard reset, unplug power up:

I tried rolling back the RP2040 BSP and Adafruit SDFat fork. No love.

testing with same hardware and seeing the same issue. i tried the sdinfo example from the sdfat fork and got this output:

SdFat version: 2.3.0

Assuming the SD is the only SPI device.
Edit DISABLE_CS_PIN to disable an SPI device.

Assuming the SD chip select pin is: 5
Edit SD_CS_PIN to change the SD chip select pin.

type any character to start

SD initialization failed.
Do not reformat the card!
Is the card correctly inserted?
Is there a wiring/soldering problem?
Is SD_CS_PIN set to the correct value?
Does another SPI device need to be disabled?
SD errorCode: SD_CARD_ERROR_CMD0 = 0x1
SD errorData = 0x0

same sd card, same featherwing but with feather rp2350 has this output:

SdFat version: 2.3.0

Assuming the SD is the only SPI device.
Edit DISABLE_CS_PIN to disable an SPI device.

Assuming the SD chip select pin is: 5
Edit SD_CS_PIN to change the SD chip select pin.

and the imagereader example also works.. maybe an issue for the sdfat library?

@mikeysklar i switched to a feather rp2040 prop-maker feather just to double check and the code was working which seemed odd. this reminded me that the rp2040 feather pins are different in arduino, the usual pin 5 is actually pin 7. updated the code and it is working

i'll add an ifdef to the example

[mikeysklar]

@BlitzCityDIY nice work!

That makes more sense that the RP2040 SD support was never put into the example code. I went on a tangent looking for what had changed.

Tested your ifdef for RP2040 pin7 PR and it worked for me.

Initializing filesystem...OK!
