Hello,

With reference to my previous case I continued to work on TC358840 driver.

After changing some driver code now kernel module is engaged , video 0 is generated.
But now when I tried to start streaming first image comes but then it stuck.
I its gives no_sync error.

Can somebody guide me what I missed the setting driver?

Thanks.

hello rusurya,

this looks like an issue of bridge driver,
could you please give it a try to configure the clock mode as discontinuous mode for testing.
you may double check whether it’s keep sending frames to CSI channel.

furthermore,
please see-also Topic 305036 for reference.

There is no update from you for a period, assuming this is not an issue anymore.
Hence, we are closing this topic. If need further support, please open a new one.
Thanks

hello rusurya,

please refer to Property-Value Pairs section, you may give it a try by adding discontinuous_clk= "yes"; into device tree as well.

BTW,
is it possible to probe the MIPI signaling to ensure there’re packet sending to CSI channel?
