RP2040-PICO-PC SDCard GPIO-Pins?

[guidol]

as per example from your Webpage
https://github.com/OLIMEX/RP2040-PICO-PC/blob/main/SOFTWARE/no-OS-FatFS-SD-SPI-RPi-Pico/simple_example/hw_config.c

the GPIO pins for the SDCard should be
.hw_inst = spi0,  // SPI component
        .miso_gpio = 4,  // GPIO number (not pin number)
        .mosi_gpio = 7,
        .sck_gpio = 6,
        .ss_gpio = 22,


I also did try this config for RunCPM to gain SDCard-Access:
// MicroSD Pin Definition for RP2040-Pico-PC board
// Pin  6 - GPIO 4  MISO
// Pin 29 - GPIO 22 Chip/Card-Select (CS / SS) SPI0_CSn1
// Pin  9 - GPIO 6  Clock (SCK)
// Pin 10 - GPIO 7  MOSI

but the SDcard couldnt be init/opend via SDFat-Library.
Also did try 10Mhz and not 19Mhz as normal.

What are then the correct settoings?

What SDFat implementation are you using? Did you try few different implementations for RP2040, like this one, for example:

Yes - I used SDFat v2.3.0 like on all mY other RunCPM projects with Pico's, ESP32, STM32, AVR Due.

So it isn't the SD Library... It has to be that pinout.

What's the correct GPIO-Pinout for the
RP2040-Pico-PC?

Also this SDCard does work in different platforms of your hardware schematics.

On a breadboard this does work with RP2940 and RP2350.

What SDFat implementation are you using?

I took the PinOut from the Rev-B-PDF on github, but my board does
show Rev D
Is there a PinOut change between Rev B and Rev D of the RP2040-Pico-PC
for MicroSD1?

Thank you for this observation, indeed newer revisions were missing. I've now uploaded the files for revisions C and D and the major revision changes. Changes are here:

https://github.com/OLIMEX/RP2040-PICO-PC/blob/main/HARDWARE/README.md

Sadly, I don't think the changes affected the mode or the pinout of the SD card connector. There are some improvements to the SD connector.

What's the correct GPIO-Pinout for the RP2040-Pico-PC?

Your pinout seems proper:

MOSI - GPIO7
MISO - GPIO4
CLK - GPIO6
CS - GPIO22

I see that we test the SD card during quality tests via software means. What I can do is I can send you the test code and maybe you can compare with your side. I will send you link in a personal message.
