iMX93EVK: Can't load AP1302 firmware onto RPI-CAM-MIPI board

[andyclayton]

I have an iMX93EVK, running the supplied factory image and a RPI-CAM-MIPI board.

I have followed the instructions contained within

https://docs.nxp.com/bundle/UM11933/page/topics/getting_started.html

and I get the following error when trying to load the firmware.

[ 2.654564] ap1302_mipi 2-003c: AP1302 Chip ID is 0x265
[ 2.659861] ap1302_mipi 2-003c: Direct firmware load for imx/camera/ap1302.fw

[ 9.012548] mx8-img-md: created link [ap1302_mipi 2-003c] => [mxc-mipi-csi2.0]

As a result of the above error I am unable to grab any images from the camera.

Any help would be appreciated.

Maybe you can refer to my previous debug note:

I am seeing the same error using iMX8MP with an AP1302 on a custom board,

[ 1.824349] ap1302_mipi 3-003c: AP1302 Chip ID is 0x265
[ 1.829670] ap1302_mipi 3-003c: Direct firmware load for imx/camera/ap1302.fw failed with error -2

[ 6.180342] ap1302_mipi 3-003c: Failed to request_firmware

In addition to the AP1302 I also see an error with loading the sdma-imx firmware

[ 0.165676] imx-sdma 30bd0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2
[ 1.829670] ap1302_mipi 3-003c: Direct firmware load for imx/camera/ap1302.fw failed with error -2

I have seen community responses regarding sdma-imx firmware error being casued by the driver being intialised before the rootfs is available, I was wondering if the issue with the AP1302 firmware is the same.

I have already downloaded that file, renamed it and placed it in /lib/firmware/imx/camera as directed in the document.

The file is found but there is an error programming it

Hello,

You have to download the ap1302 firmware from ONSemiconductor, and rename it as ap1302.fw

Please check it:
