Hi,

This line will mapping channel sequence to 0,1,2,3,3,4,5,6 instead of 0,1,2,3,4,5,6,7

Again, forum is not a appropriate place to report code issue.

Hi Keelung Yang,

Yes, this is a mistake, we will fix it in the next release.

Meanwhile, can you please change this statement to ch = (NUM_CAPT_CHANNELS)* id + q;

Regards,

Brijesh

One question, are you using this demo for multiple channels? Because this demo is only for single camera input, so only VC ID at the index 0 and channel map at the index0 will be used..

Hi Brijesh,

Not exactly.

I'm using this demo to bring up camero which sent raw data to CSI_RX_1

And I'm using PSDKR v7.2 to do this but after changing CAPT_INST_ID from 0 to 1, sensor data is still sent to CSI_RX_0.

So I cheched PSDKR v7.3 and migrate it's channel mapping into v7.2

Hi Keelung Yang,

ok what's is the virtual channel id you are using for instance-1? Is it 0x4?

Hi Brijesh,

It's 0x02 and CSI_RX_1 works after migrating channel mapping code from v7.3 to v7.2

I'll try 4-7 late.
