Changes make targets:
- prog_flash in hw/application/Makefile which flashes only the
bitstream is renamed to prog_flash_bs.
- prog_flash in hw/application/Makefile is modified to flash the
bitstream, the testloadapp.bin in app slot 0, and the partition table.
- flash in contrib/Makefile is modified to use prog_flash from
hw/application/Makefile
- Point out licensing terms in docs.
- Add missing SPDX tags
- Update the SPDX checker to check all the files we want to check.
- Include spdx-ensure in CI.
Add a tools/README.md.
Remove:
- create_flash_image.py: role now overtaken by tkeyimage which does
more.
- reset-tk1: Leftover from when production_test was removed.
Rename:
- makehex.py: Moved up one level.
Usage:
./partition_table -o flash.bin -f -app0 path/to/app
Will produce a flash.bin that can be used for qemu.
- Adjust the size of the partition table.
- Refactor and rename genPartitionFile().
Allows an app to determine which type of device it is running on.
- Reserve vendor ID 0x7357 for people using Unlocked.
- Use Castor product ID.
- Serial number is just nonsense, as before.
When starting, reset the USB controller to only enable the USB CDC
endpoint and the internal command channel. If the app resets firmware,
but had differend endpoints enabled, we want to go back to a known
state.
The qemu_firmware is too large for the real hardware's 8k of ROM. The
emulator, however, has lots of ROM. Use a different linker script for
to reflect this.
Add a new syscall to enable an app to get the data left for it by the
previous app in chain.
- Change testloadapp to leave some data for the next app to read.
- Call system call with:
uint8_t next_app_data[RESET_DATA_SIZE];
syscall(TK1_SYSCALL_GET_APP_DATA, (uint32_t)next_app_data, 0, 0);
To retain the default behaviour from Bellatrix, we introduce a simple
default app. If used on flash app slot 0 we get the same behaviour as
in Bellatrix, that is, waiting for an app from the client.
Since we want to keep the user of the timer to the device apps, remove
the use of the timer for implementing a delay when writing to flash.
Let's try without any delay what so ever, just busylooping the query
to the chip.
- Set LED color to white when firmware has initialized
- Set LED color to black when changing state to loading
- Set LED color to blue when starting testloadapp
- Update mgmt app allowed digest since testloadapp changed
Instead of using 16 byte BLAKE2s with a dummy key, use plain vanilla
unkeyed 32 byte BLAKE2s for partition checksum.

- Rename functions, defines, et c to indicate that it's a checksum
over the partition, not necessarily a cryptographic hash digest even
though we use a version of BLAKE2s.
- Add comments describing where the checksum is stored and what it is
used for.

When we pass pointers in system calls these pointers should point to
app RAM, not any other parts of the memory map, and especially not to
memory like FW_RAM that is only available in in a higher privilege
mode.

Limit flash offsets passed to syscalls. Be sure to check the limits
before doing any form of calculation with the passed values.
