Hi @LloydShelby,
It looks like you are applying the wrong overlay since it’s called apalis-imx8_hmp_overlay.dtbo, instead please load the verdin-imx8mp_hmp_overlay.dtbo. This overlay is available on TorizonCore 6. Can you please share which version of TorizonCore you are using?
The kernel panic you are seeing is because Cortex-M is trying to use the UART to print messages and the same UART is not disabled on the Cortex-A (Linux) side, therefore there is a conflict between the two cores.
Please check this thread for more information about this issue:
Let me know if you have any questions.
Best Regards,
Hiago.
