Userdata import from SD card #18

Closed megari closed 5 years ago

megari commented 6 years ago

Needs more testing. Only compile-tested after rebasing to current release branch.

One thing of note is that importing userdata and upgrading the firmware are similar operations in that blocks are copied verbatim from an SD card to the Flash memory onboard the OSSC, so a function to do just that task was factored out and made both use it.

To save memory, there is only minimal validation of the userdata to be loaded. However, 512 bytes have been intentionally left reserved for a header with a checksum.

Rebased on top of current release branch.

megari commented 5 years ago

Rebased on top of rv-integration.

Please note that the rebased code has only been compile-tested.

There seems to be quite a bit of space left even after this patch set:
