camera porting and zephyr on i.mx 93 evk

csalitre — Mon, 21 Jul 2025 16:36:36 GMT

Hello everyone! Noobie here,

I have read zephyr documentation on their support for NXP i.MX93 EVK. I am a little confused on what is the best approach. My main use case is camera porting, so my understanding is that I will need to port Zephyr on the A55 core. I have seen some experimental examples on Zephyr's repository, but no official support for MIPI-CSI.

My other question is should I run Zephyr on both A55 and M33 or just on the A55?

Thank you!

Hi @csalitre

Just let you know we are developing a Bar scanner demo for FRDM-93 board, this demo is running on Zephyr OS, A55 core, will support MIPI-CSI. it is very similar to your requirements.

Regards

Daniel

Hi,

For i.MX93, Zephyr is typically used on the M33 for real-time control, while Linux on the A55 handles camera and media pipelines. Zephyr on A55 is currently suitable mainly for early driver bring-up; official MIPI-CSI camera support is still not available in Zephyr.
