Secure boot for 32-bit Microcontrollers!
Hi, boot/zephyr/boards/disco_l475_iot1.conf contains CONFIG_BOOT_MAX_IMG_SECTORS=256 That will result in "mcuboot: Failed reading sectors; BOOT_MAX_IMG_SECTORS=256 - too small?" upon boot. The error messages disappear if you change that line to: CONFIG_BOOT_MAX_IMG_SECTORS=512 This...
Currently, the simulator does not test that MCUboot properly handles images that are as large as possible. There are multiple things to consider here: - [ ] Writing sim code...
The signing script seems to hardcode the AES key length to 128 bits when using ECIES: https://github.com/mcu-tools/mcuboot/blob/93d02179b32056320deaac7919247173793febbe/scripts/imgtool/image.py#L287 The HKDF length is 48 bytes there: 16 bytes for the AES key...
In the documentation file index.md, line 42, there is currently this sentence: > There is also a document about **[signed images](signed_images.md) that is out of date.** You should use `imgtool.py`...
We are planning to start using MCBoot soon, and I have some questions please. Basically, our board has two MCU, ESP32 and STM32, we are planning to flash the STM32...
requires https://github.com/zephyrproject-rtos/zephyr/pull/44512 **DNM** before ^^ This Patch introduces possibility to trigger the serial recovery mode by the application using dedicated zephyr-rtos API. Additionally Kconfig and USB DFU class invoking was...
Hi all, I have been trying to make decrypting of firmware image on MCUboot but have not been successful. **Platform**: Zephyr **Board**: nrf5340dk_nrf5340_cpuapp This is what I've done; **On the...
In certain scenarios, additional tests in the updated firmware are performed to determine the success of the update. Nevertheless, in those cases also the downgrade prevention is of interest. This...
`BOOT_SERIAL_INPUT_MAX` is currently set to 512 bytes. This means that around 1kB of RAM is dedicated to `in_buf[]` and `dec_buf[]`, which is a significant amount on memory-constraint targets. Zephyr can...
Congratulations on fork number 400 as I just found out about the project and forked it to try out in my free time. Is there a plan to integrate with...
