i have a camera sensor,when i set output data rate 2.5Gbps,will report error
[ 245.431834] tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 84, flags: 0, err_data 4194400
[ 245.478504] tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 85, flags: 0, err_data 4194400

[ 245.572273] tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 87, flags: 0, err_data 4194400

but when i set output data rate 2.2Gbps,can receive normally
why did this situation occur

CPHY or DHPY?
What’s the trace log tell?

DHPY

Did you boost the clocks to try?

echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/mrq_rate_locked
cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate |tee /sys/kernel/debug/bpmp/debug/clk/vi/rate

i have already tried this command
but the phenomenon is still the same

7

do you have any other opinions,or is there any other information you need to know

8

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

Is this still an issue to support? Any result can be shared?
