MR-CANHUBK344 - Zephyr MCUboot

[flynnty]

Has anyone got this mcuboot working on S32k344/CANHUBK344, Ultimately I want to switch from UART to CAN DFU using MCUboot but I need to get the UART option working first. There's a tonne of build warnings when I configure like I have for STM32 NUcleo board. Ultimately I can get MCUboot bootloader onto the CANHUBK hardware and it activates LED to indicate it's in boot loader mode but I can't write to it to update the firmware using AuTerm.

I dont know if I need some custom flash-controller driver to achieve this.

Hello @flynnty ,

Although I do not have hands-on experience with MCUboot, based on available documentation, I would recommend using the MR-CANHUBK3 — Zephyr Project Documentation , which officially supports this board and includes integration with MCUboot.

Please note:

• NXP does not officially support MCUboot within the S32K3 SDK or S32 Design Studio.
• MCUboot is an open-source bootloader maintained by the Zephyr community.
• Using Zephyr provides native support for UART DFU via mcumgr, and includes board-level configuration for MR-CANHUBK344.
• CAN-based DFU is not supported out-of-the-box and would require a custom transport implementation.

If you are currently trying to integrate MCUboot manually into an NXP SDK-based project, this would require a custom flash driver and significant adaptation effort.

Best regards,

Pavel
