ESP32S3 SD-card init problem

[stefan.erni]

Hi Ben

The SD card works with the old SD component, but I don't have any free SPI buses left because of the display and the AD converter.

I'm having trouble with the C code insert from You.

Does it just need to be in a C code component, or should it be added as a supplementary C code?

Hi to All

There is one remaining issue that I have not yet been able to identify or resolve.

The FC11 fails to initialize the SD card on this board.
However, the same SD card operates reliably with FC11 on other board, such as ESP32-S3 and ESP32-WROOM boards.

Interestingly, similar issues can also be observed on a SparkFun board with ESP32-S3 mini.

It's a small board that's placed underneath an Adafruit board, with an amplifier IC, a 24-bit A/D converter, and an SD card.
Fortunately, I can still make changes like I could still swap the pins from the card.

Hi to All

I ran a test on Ben's board and used the loop to initialize the card every 10ms .
I didn't use an SD card, but I checked it with the KO, and the signal was perfect.
Then I switched the clock to a free port (GPIO 19 and GPIO 20), and the clock was perfect there, too.

I added the same loop to my board
But the clock isn't working on my board. It's just always 0 volts.

Both are ESP32-S3 but my is a mini

loop for oscilloscope on Ben's board:

Hi Ben

Would it be possible to provide me with the latest File_ESP32_SDMode component?

[BenR]

Of course

It should be on the wiki but if it's not then this gthub contains nightly builds of the latest files straight from the source.

Hi Ben

Thanks. Creating my own component File_ESP32_SDMode_erni worked out well !

But then I need a little help finding the code to return 0 for “OK” and 255 (>0) for “not OK.”

You likely need to look here.

C:\ProgramData\MatrixTSL\FlowcodeV11\CAL\ESP\ESP_CAL_File.c


The init function is defined as an embedded function which just calls the C CAL function.

Hi Ben

I'm one step further.
In the .h file
On your board (with Devkit), the pins are set correctly. On my ESP32 S3 Mini, they're not. All are set to 0

Hi Ben

I think I've found a solution.
I need to use $portA. The map initially has a value of 0 now

Thanks Stefan I'll see if I can resolve this problem.
