When I set SDMMC1 to SD 4bits wide bus, the RCC shows a warning “partly disabled conflict with : SDMMC1 : SD 4bits wide bus”. At this time, when I wrote a program on the board and operated it, “FR_DISK_ERR” occurred. Is the error caused by RCC warning?
No, the RCC warning is just letting you know that some part of the RCC can't be enabled because its pins are being used by the SDMMC. It's not the cause of the error.
