I didn`t find where to use this function in my code (spi_device_polling_transmit).
I fixed the stack overflow by setting the stack size to LWIP -> tcp/ip -> 8190.
But still new problem:

I found out what the problem was. It was the sd-card spi.
If I comment out the sd_card_mount() function, the problem disappears.
Why did the "spi transmit failed"?
I did not use the spi functions directly. I create a pointer to the spi bus and then pass it to the following components (w5500, sd card file system)
Is it possible that I have the spi peripheral configured incorrectly?
Or maybe I forgot to execute free (any malloc) on the http server somewhere?
- W5500 - SPI2_HOST and SPI_DMA_CH_AUTO
- SD-CARD - SPI3_HOST and SPI_DMA_CH_AUTO
Next, I try to make the functions clear:
