Hi NV TEAM，
I debug imx390 + max9295 + max9296a in TX2 NX platform， Soc can not capture image. dmesg show below log.

hello a1ayin,
there’s an error with CHANSEL_FAULT.

the error code shows there’s PIXEL_SHORT_LINE, which means the receiving lines is less than expectation.
since you’re working with a SerDes chip, please also check the configuration is correct.
Hi JerryChang,
It mean active_height larger than serder output actual height, right?
yes, please review the SerDes configurations.
Hi Jerry，
Soc can get image from serder after changing serder’s configuration, but kernel show below error log.

these logs indicate that there are still errors in the package，right？ how to debug these errors？
hello a1ayin,
it looks all normal according to VI tracing logs.
for example,
CHANSEL_PXL_SOF: this meant VI engine have received start-of-frame correctly.
CHANSEL_LOAD_FRAMED: this meant buffer write has done.
CHANSEL_PXL_EOF: this meant VI engine have received end-of-frame correctly.
please also check the frame-rate is streaming as expected.
you may try setting up a terminal for running $ dmesg --follow to catch the kernel logs simultaneously.
Hi Jerry,
I use v4l2-ctl tool to capture image,the frame rate is unstable and constantly changing .

it makes sense now…
it’s sometime VI cannot wait start-of-frame to cause unstable frame-rate. and… it has recovered internally so that the capture pipeline won’t crash.
is this due to clock configuration?
please try commands as following to boost all the VI/CSI/ISP clocks.
sudo su
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
cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/isp/rate
cat /sys/kernel/debug/bpmp/debug/clk/nvcsi/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate
cat /sys/kernel/debug/bpmp/debug/clk/emc/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/emc/rate
Hi jerry,
The previously provided logs were all captured while boost all the VI/CSI/ISP clocks. If not boost all the VI/CSI/ISP clocks, soc cannot get image. I also think there is a problem with the clock. Which clocks do I need to check？
hello a1ayin,
please check device tree property, serdes_pix_clk_hz.
you may see-also developer guide for SerDes Pixel Clock section.
may I also confirm how many camera streams you’ve enabled with SerDes chip?
here’s developer guide, Jetson Virtual Channel with GMSL Camera Framework as reference for developing SerDes driver.
Hi Jerry，
soc can capture image stably after change serdes pixel clock. Now i want to configre gpio07 as pwm to sync camera, but i don’t know gpio07 belong to which pwmchip. I need your help.
hello a1ayin,
may I confirm the pin you’re using?
you may check pinmux spreadsheets, and please try using Jetson-IO for Configuring the 40-Pin Expansion Header.
Hi jerry，
I’m using CPIO3_PU.00, I had configured this pin as GP_PWM1 function in pinmux spreadsheets. how to output pwm next step?
hello a1ayin,
you may set PWM periods/duty_cycle configurations.
please populate the channel ID via sysfs. $ echo <channel_id> > /sys/class/pwm/<pwmchip instantiated>/export
for example, $ echo 0 > /sys/class/pwm/pwmchip4/export
a new channel-id will create under pwmchip4, path… /sys/class/pwm/pwmchip4/pwm0
then, please configure duty_cycle, period, and toggle enable to enable PWM.
