This macrocontroller uses our SD controller implementation which supports MicroSD, MicroSDHC, and MicroSDXC cards. This controller has been tested with Sandisk Extreme SD cards which allow read speeds up to 20.5MB/s, and write speeds up to 21.5MB/s.
The support for the SD controller is provided by sdctl which serves up a /dev/nbd0 for the entire block device. The kernel also includes a module that will break this up into partitions. Our default software image contains 2 partitions:
| Device | Contents |
|---|---|
| /dev/nbd0 | SD Card block device |
| /dev/nbd0p1 | Kernel and initramfs |
| /dev/nbd0p2 | Full Linux Root |
