FRDM-IMX93 not recognizing RPI-CAM-MIPI

jventura — Tue, 09 Jun 2026 14:35:08 GMT

Hi, i´m trying to make RPI-CAM-MIPI work with the FRDM-IMX93 board.

I followed the user manual for the board:

https://docs.nxp.com/bundle/UM12181/page/topics/camera_module_rpi_cam_mipi.html

I connected the camera as instructed.

I got the ap1302_60fps_ar0144_27M_2Lane_awb_tuning.bin from ONSEMI github (https://github.com/ONSemiconductor/ap1302_binaries/tree/main/NXP_i.MX93), renamed it and put it in the board:

root@imx93-11x11-lpddr4x-frdm:~# ls /lib/firmware/imx/camera/
ap1302.fw

I rebooted the camera, but the log wasn´t the same as in the manual:

and the camera doesn´t seem to appear:

I've rechecked everything. I'm stuck. Any ideas what i should try?

Hi @jventura

Can you share the photo to show the connection between RPI-CAM-MIPI and FRDM93?

Best Regards,
Zhiming

I´ve attached the photos, but i also checked continuity with a multimeter and it´s ok, the pins on the FRDM are reaching the CAM ones...

Hi @jventura

Your connection is wrong, the blue side should be the same as the camera side.

thanks @Zhiming_Liu

I checked it so many times, and every time i missed.

Anyways, it got better but it seems I still have a problem with the .fw:

Is the ap1302_60fps_ar0144_27M_2Lane_awb_tuning.bin from ONSEMI github (https://github.com/ONSemiconductor/ap1302_binaries/tree/main/NXP_i.MX93) the correct one?

Hi @jventura

ap1302_60fps_ar0144_27M_2Lane_awb_tuning.bin is correct one. Please try below suggestion from reference manual

A firmware named ap1302_ar0144_single_fw.bin is needed. Put it under the /lib/firmware folder.
