- I am using 32Gb pendrive using FAT32 format.
- Heap size is 2000.
- I connected DP and DM pins directly to USB A type connector.
- DISKIO.C file looks fine.
When I try to mount USB device it shows FR_DISK_ERR. Also, when I use f_mkfs it shows FR_NOT_ENABLED.
Can I get example code/project ?? It will be a good help.
