D32 Pro defines TF_CS, SD card library uses SS

[mtfurlan]

If you run the SD_Test example: https://github.com/espressif/arduino-esp32/blob/master/libraries/SD/examples/SD_Test/SD_Test.ino
on a lolin d32 pro https://github.com/espressif/arduino-esp32/blob/master/variants/d32_pro/pins_arduino.h
using the SD card slot, it will fail with Card Mount Failed, because the SD library uses SS as the default slave/chip select, while the d32 has TF_CS defined for the slave select.

In the example if you set the CS, it runs as expected.

-    if(!SD.begin()){
+    if(!SD.begin(4)){

I think the actual solution is to also define SS for the D32 pro?

totally correct!
