PROGRESS: To simplify the problem I removed LVGL and its SPI 2 configurations, tried to run MmcSDSpi with SPI Port 3. Initially it didn't work due a restriction in Nuttx (esp32_mmcsd.c Line 70), but after I changed the expected port number from 2 to 3, I could mount and use the MMcSD as expected with SPI Port 3.
This also proves that there is no a short circuit on GPIO13 trace and it works correctly with a proper software. https://ta1db.5g.com.tr/murat/SPI2-SPI3-lvgl-4.JPG Now I will try to find who is interfering to GPIO13 line.
