Beaglebone Black Wireless SDHC / SDXC support?

Dear All,

If I am not wrong, BBBWL 's SDIO interface supports SD and SDHC, and does not support SDXC, right?

I am confusing about the this Kingston microSD (PN: SDCIT/16GB) card compatible with BBBWL, or not?

Best Regards,

  SD => LESS than 4GB, native FAT file system
  SDHC => (high capacity) 4-32GB, native FAT file system
  SDXC => (?eXtreme capacity) 64GB and larger, native exFAT file
system

(though since the BBB reformats into one of the Linux ext# file systems,
knowing the native format doesn't mean much... More of a problem on R-Pi,
since their NOOBS releases start as FAT, and format the rest of the card
into ext# during install).

  I know of NO cards in the 16GB range that use SDXC protocol.

Any SD, SDHC, or SDXC should work on any BBB. As long as you don’t try to use any “funny” cards such as the old non-standard 4 GB SD models, you shouldn’t have any issues.
Note that for programming and booting a full system image (with desktop interface) you really want an 8 GB or larger SDHC card.
Otherwise you can use any cards that you want and put any filesystem on them that you want that Linux supports.

  Based upon a search, the chipset is SDIO v2 compliant. SDXC is SDIO v3
spec.

100% correct..

Some SDXC SDIO v3 cards support SDIO v2 transfer modes, if you search
this forum you'll find a bunch of test'ed microSDXC cards that work
fine..

What i advise everyone, "buy" "1" and test it before you put in a
order greater then 2...
