Need Disk i/o.c for mmc flash for FATFS

Hi all,

I am using the MTFC8GAMALNA-AAT 8GB flash memory via SDMMC1, operating in MMC 4-bit wide bus mode, along with FATFS (M7). I now require the diskio.c file. Kindly provide it, or if you have any related example code, please share that as well. Please note that I do not want to use DMA or an RTOS for this implementation.

Thanks

Hi @Saket_Om ,

Thank you for your response.

I would like to ask if you have a ready-made diskio.c  implementation that supports MMC in 4-bit mode. If available, I would greatly appreciate it if you could share the file or point me in the right direction.

Best regards,

Mayank
