S32K344 / MR-CANHUBK344 - Zephyr Support

[HTECH_LYONS]

Can anyone on the forum confirm that the MR-CANHUBK344 dev board is still working under the latest Zephyr releases (v3.6.0 or v3.7.0-rc3)?

While attempting to bring up the dev board via JLink (v7.98a), we are getting many spurious faults.

Both the board and the debugger seem OK, they will run the default example S32DS project without issues. Seems to be more related to the S32K3's integration into the Zephyr platform, more than likely in the early kernel init stages from what we can tell.

Using Ozone with the Zephyr Blinky project on v3.7.0-rc3, we see BusFaults with BFAR registers of 0x5AA55AC0 almost immediately after reset.

Hopefully it's just something in our configuration, or if anyone has a working solution, what branch/tag of Zephyr are you using?

Thanks!

VaneB,

Thank you for the response. I can confirm that Zephyr 3.3.0 is working with MR-CANHUBK344 dev board and J-Link.

Hi @HTECH_LYONS 

The NXP Auto Zephyr Board Support Package (Zephyr BSP) with S32K344 Support (MR-CANHUBK3 Board) contains the Zephyr RTOS source code based on community version 3.3.0.

The software is Code Drop qualified, so the implemented features are not fully tested and are not intended for production use. Its functionality is not guaranteed by versions different from those used for its development and we do not support for ay application out of this scope.
