Driver GMSL1 cameras using MAX9296, preview the cameras failed?

Hi NV_Team,

I’m using Xavier to driver GMSL1 cameras using MAX9296, but there is an error when preview the cameras. Can you help to check my csi log, and give me some advice about how to fix the problems? what about the CSIMUX_FRAME/CHANSEL_SHORT_FRAME/CHANSEL_FAULT means in the csi log and how to fix them by modifying the source code?

HW:
Xavier + MAX9296 + MAX96705/AR0147 （4Lanes， 1280x720@30fps）
SW:
JetPack4.5

hello Luna2020,

tracing logs, SHORT_FRAME means the coming lines less than VI engine’s expectation.
could you please revise the active_h in the device tree property for testing?
BTW,
it also helps if you’re able to enable test-pattern-generator on the SerDes chip,
could you please configure that to narrow down the issue?
thanks

Hi JerryChang,

I have tried to modify active_h from 720 to 700, there is still "SHORT_FRAME " error, is there any register or csi log can check the actually pixel recieved by VI engines?

This SerDes driver MAX9295A/AR0231 is okay, so the hardware is fine.

hello Luna2020,

I think part of the signaling should be correct.
please also check below example,
it’s shown the signaling of start-of-frame and also end-of-frame, the timestamps values also looks correct.
bit-16:32 of CHANSEL_PXL_EOF also indicate the line-numbers received by VI engine.
0x02cf = 719d which shows 720-lines, (counts start from zero), so it equal to the active_h=720 in your DT configuration.

CHANSEL_PXL_SOF channel:0x23 frame:0 vi_tstamp:2915172497 data:0x00000001
CHANSEL_PXL_EOF channel:0x23 frame:0 vi_tstamp:2915779732 data:0x02cf0002

however,
there’s CHANSEL_FAULT error after 1st frame,
for example,

CHANSEL_FAULT channel:0x23 frame:0 vi_tstamp:2915780187 data:0x02d00040

this is a PIXEL_RUNAWAY failure, the line number here shows, 0x02d0 = 720d
we may dig into the signaling after frame-end. is there anything, such as embedded metadata coming after frame-end packet?
thanks

Hi JerryChang,

Thanks for your information. The ‘PIXEL_RUNAWAY’ means I need to add ‘active_h’ to verify it ?
I also see an error tracing log with ‘CSIMUX_FRAME’. Does it mean the FE packages lost?
“The bit 5 and 7 indicate lose the FE package cause the FS_FAULT — (A frame start occurred before previous frame end)”

I defined embedded metadata in dtsi, but it is set to 0.

hello Luna2020,

you may have a try, but I’m guessing there’s actually an issue behind frame-end.
it’s VI engine to expect a complete frame signaling within SOF/EOF; CSI MUX report an error if there’s additional lines received after end-of-frame.
so, the expected signaling comes as following, FS, SOF, Active Pixels, EOF, FE…

Hi JerryChang,

I modify the max9296 registers settings and solved this problem.

Thanks for your support.
