I am doing sd card operation using stm32f103c8t6. For sd card operation, i use FATFS files from stmcubx. But the problem is, that this generated FATFS file is only supported for up to 32Gb.

Further above the size of sd card operation, it doesn't work. Please let me help me out with this issue.

Thank you in advance.

Check EXFAT usage is enabled via ffconf.h

Also use a current version of FATFS for large media, the 2017 release has known issues.

Check DISKIO layer for operational limits. The F1 should be capable of using 400GB+ media.​
