BTT_SKR_Pro v1.2 onboard sd_card

[Melkiyby]

Hello. I'm trying to set up sd card support. I figured out the problems during compilation, but still an error 60 mounting the SD card.
I commented the exp2 part and uncommented it from the onboard

`//#if SDCARD_ENABLE
// Connect to the  EXP2 Header
//#define SD_CS_PORT                  GPIOB
//#define SD_CS_PIN                   12
//#define SPI_PORT                    2 // GPIOB, SCK_PIN = 13, MISO_PIN = 14, MOSI_PIN = 15
//#endif

//*
#if SDCARD_ENABLE
// On board socket- flaky?
#define SD_CS_PORT                  GPIOA
#define SD_CS_PIN                   4
#define SPI_PORT                    11 // (MCU port 1) GPIOA: SCK_PIN = 5, MISO_PIN = 5, GBIOB: MOSI_PIN = 5
// PB11 - TF_SW - card detect
#endif
//*/`

I had the same issue, with the same board (SKR PRO V1.1).
Unfortunately at the time i misplaced my issue under the core repo instead of here.
I did some testing, but at some point i got busy doing other stuff and i did not have the time to further investigate.
Meaby this info can help you and/or you can finish where i stopped:
#grblHAL/core#244

My plan was to one day pick this back up and go further with testing...

There is a typo in spi.c... 5 should be GPIO_PIN_5.
