Hi nvidia team:
I am using imx390->max9295a->max96781->orin to get GMSL camera video for ADAS.
but met a problem and don’t know how to fix it.
most time the video is ok,but when my hand close to camera,the orin reset the channel.
hear is the scene:

the console outpu below log:

Looking forward to your reply.

If the first nonembedded data packet after an NVCSI FS packet from an input stream does not match any channels at all, a “no-match” notification is emitted from CHANSEL.

what is difference between ccannel_id and tag_channel?

7

It’s YUV422 output sensor?
There’s NOMATCH for NvCsiDataType_YUV422_8 of Line Start

CHANSEL_NOMATCH channel:0x50 frame:0 vi_tstamp:3288112464032 data:0x00000000000003c9

Hi ShaneCCC:
It’s raw sensor through ISP output YUV422 .

9

Could you modify the CID function in sensor driver like exposure/Frame Rate to dummy function to try.

10

Hi ShaneCCC:
The camera is default config and we can not config it.
by the way, where is th CID function ? which file?

11

Should be at …/kernel/nvidia/drivers/i2c/nv_imx390.c

Reference to below link for customized kernel.

Hi ShaneCCC:
if we cannot modify CID function,do you have any other suggest to debug?
and sensor output YUV422_8 , why not nomatch NvCsiDataType_YUV422_8 of Line Start ,in general,how is it caused?

13

Looks like the max96781 configure the incorrect virtual channel ID in the payload.

CHANSEL_NOMATCH channel:0x50
bit 6-7 tell the VCID(Virtual Channel ID)

Hi ShaneCCC:
sorry for later reply
and I w , the chip is max96712.
and follw your suggest .we are focus on max96712 .
