where to get imx8mp airobot ap1302 camre fw

[Nobita]

Hello Sirs,

I am using imx8mp ai robot platform, and my code base is imx-yocto-bsp-5.10.72-2.2.3 refers to https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-%E6%9C%BA%E5%99%A8%E4%BA%BA%E5%B9%... , howerver when I try to use the rpi-cam-mipi on it，it says it need fw ap1302_ar1355_1080p60_27M.bin，however I cannot found it on the repo https://github.com/ONSemiconductor/ap1302_binaries which is recommended by the rpi-cam-mipi doc， please tell me where to get the corresponding firmware of this camera sensor.

Share my debug note and patches, hopes that can help other people.

Finally, I have made the driver works, but I cannot preview the camera or record any YUV data to file, following are details:

1. change my code base to 5.15.71-2.2.0 refers to https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-%E6%9C%BA%E5%99%A8%E4%BA%BA%E5%B9%B... , because this code base 's kernel version is 5.15.71 which has the same driver of ap1302 as imx93 does;
2. patch the attached path of kernel, the patch is about the dts config for imx8mp-ai-robot platform;
3. copy the imx93's ap1302.fw to the bord refers to https://docs.nxp.com/bundle/UM11933/page/topics/getting_started.html , I got the log says that the fw load success:

[    2.805324] ap1302_mipi 1-003c: AP1302 Chip ID is 0x265

    4. use the comand to preview or record YUV data fo file refers to https://docs.nxp.com/bundle/UM11933/page/topics/software_introduction.html , unfortunately it got nothing, no preview on my HDMI monitor, the record file size is 0, here is the terminal log when do preview

    5.I check the voltage test points on RPI-CAM-MIPI board, the voltages are correct.

Please give me some advice to inspect the issue.

Thanks in advance.

do you have imx8mp evk board or 93evk board? I don't have airobot board to test this, but verified on imx8mp evk board, I don't know if this code can work on airobot board or not

[Nobita · Accepted solution]

Sorry for that I forget to share my latest news, I use another bord, it works well!

Thanks!
