The comment labeled IMG_STATE_TESTING as an 'ELF loading state', but
the constant is wolfBoot's general dual-bank confirm/rollback marker:
it is set on the BOOT partition after every swap (update_flash.c,
update_flash_hwswap.c, update_ram.c - none ELF-specific) and cleared
by wolfBoot_success(); if still present at the next boot it triggers
a rollback. A maintainer trusting the old comment could have treated
the state as inert on non-ELF targets and disabled the anti-brick
path.
Reword to the accurate description already used in
docs/flash_partitions.md, keeping the note that it only lives on the
boot partition so it cannot conflict with IMAGE_STATE_UPDATING.
Comment-only change; no code or behavior changes.
- Check diag_erase() return value in wolfBoot_record_failure()
- Dedicated WOLFBOOT_FAILURE_PHASE_SELF_UPDATE
- Mark the diagnostics flash write buffers XALIGNED_STACK(4) for HALs
that access the source word by word
- Ensure diagnostics, update, or swap partitions don't overlap the
bootloader
When boot/update partition verification fails during boot or update,
with this option the event is logged to flash in an ad-hoc partition.
Information about logged failures is made available to the application
through an API.
* Initial port refresh for the NXP T2080 target
* IFC Flash driver and multi-core support on T2080
* Working wolfBoot test-app startup on T2080
* Support for NAII and Curtiss-Wright T2080 vendor boards
Cleanup STM32H5 HAL port.
Refactor `__ARM_FEATURE_CMSE` to `TZ_SECURE()`
Refactor attribute cmse_nonsecure_entry to use new macro `CSME_NSE_API`
Added TPM Non Secure Callable API's
Added TPM support to STM32H5 test application
- Make the update and swap partitions secure and inaccessible from the
app except via NSC API
- Add a couple of necessary new NSC functions
- Update the app to only use NSC API
- Fix hal_flash_erase to account for secure addresses
- Fix some bugs in xmodem implementation
During fallback operations, use a different encryption IV than the one
used to encrypt the backup during the update. This ensures that the same
IV is never reused to encrypt different sectors.
As reported by @reza-hdd in #589:
> When Firmware is large enough to consume all the allocated boot partition sectors, in the the final swap and erase operations (_wolfBoot_swap_and_final_erase_) the last sector of FW in Boot partition, which is used as a temporary sector for a copy operation, gets corrupted after being copied in external Swap partition and copied back. It looks like the contents are copied to the external Swap partition without being encrypted, but get decrypted when it is read back.
This was due to the function wolfBoot_copy_sector() assuming that all
copies having an external SWAP as destination would not need any
encryption, as the "normal" case during update is to copy already
encrypted sectors from UPDATE->SWAP.
In the final state, after the update is successfully applied, the
mechanism saves a copy of the last sector from BOOT->SWAP. In this case,
if the application is big enough, an extra function is needed to
encrypt the content of this last sector before writing it to SWAP.
Restoring the backup is OK (normal case SWAP->BOOT, decryption was
already there as also noted by the reporter).
- Support ELF scatter-loading on TC3xx
- Modify TC3xx HAL flash erase to support arbitrary offsets and sizes
- Realign partition size and addresses to support more efficient sector mass erase on update
- Added missing `test-app/app_sim_scattered.c`
- Added missing `test-app/sim_scattered.ld`
- Fixed comments at the end of define blocks for consistency
- Removed unused constants as indicated
