On a custom board with stm32L152RET6 cpu, I'm trying to read and write data to the SD card. I'm using stm32CubeIDE, freertos and FATFS with CMSIS v2. I configured the pins using spi3, I am calling HAL_spi3_init and GPIO_INIT. For f_mount > FA_NOT_READY.

[JBamb.1]

this was fixed when I got the user_diskio_spi.c and user_diskio_spi.h files in place from another branch...
