Other Parts Discussed in Thread: TMS320F28377D

Hello.

I have a question about USBLib of TMS320F28377D.

I want to use 64GB USB memory or SD card with TMS320F28377D.

Can TMS320F28377D mount/read/write 64GB USB memory or SD card?

Thank you.

    Wayne,

    These are limitation based on the software running on the device, not the hardware itself.  We use FATFS as our FAT stack and it has the following limitations:

    Limits

    • FAT sub-types: FAT12, FAT16 and FAT32.
    • Number of open files: Unlimited, depends on available memory.
    • Number of volumes: Upto 10.
    • File size: Depends on the FAT specs. (upto 4G-1 bytes)
    • Volume size: Depends on the FAT specs. (upto 2T bytes at 512 bytes/sector)
    • Cluster size: Depends on the FAT specs. (upto 64K bytes at 512 bytes/sector)
    • Sector size: Depends on the FAT specs. (512, 1024, 2048 and 4096 bytes)

    Hope this helps!
