Implementations

impl Bootloader

pub fn try_new(vid: Option<u16>, pid: Option<u16>) -> Result<Self>

Select a unique ROM bootloader with the given VID and PID.

pub fn try_find(
    vid: Option<u16>,
    pid: Option<u16>,
    uuid: Option<Uuid>
) -> Result<Self>

Attempt to find a unique ROM bootloader with the given VID, PID and UUID.

pub fn find(vid: Option<u16>, pid: Option<u16>, uuid: Option<Uuid>) -> Vec<Self>

Finds all ROM bootloader with the given VID, PID and UUID.

pub fn info(&self)

pub fn reboot(&self)

pub fn enroll_puf(&self)

pub fn read_memory(&self, address: usize, length: usize) -> Vec<u8>

The reason for this wrapper is that the device aborts early if more than 512 bytes are requested. Unclear why it does this…

This is a traffic trace (requesting all of PFR in one go), removing the “surplus junk”

The error is 101 = 100 + 1 = (supposedly) a flash driver “alignment” error (?!)

The interesting thing is that at the point where the device aborts, there are 8 bytes remaining, which it otherwise produces in a final

TODO: should we just enter our desired length anyway, and handle such situations? As in retry at the new index, with the reduced length? Instead of using a fixed 512B chunking?

TODO: Need to expect errors such as: Response status = 139 (0x8b) kStatus_FLASH_NmpaUpdateNotAllowed This happens with read-memory $((0x0009_FC70)) 16, which would be the UUID

TODO: Need to expect errors such as: Response status = 10200 (0x27d8) kStatusMemoryRangeInvalid This happens with read-memory $((0x5000_0FFC)) 1, which would be the DIEID (for chip rev)
