Tips for debugging

TX1

  • if you saw below error message
tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
  • please check below 4 items in your sensor device tree, these should follow the settings in your sensor datasheet
                                mode0 {
                                        cil_settletime = "0";
                                        active_w = "1920";
                                        active_h = "1080";
                                        embedded_metadata_height = "1";
  • if you saw below error message
video4linux video0: MW_ACK_DONE syncpoint time out!
  • Enable the csi debug message from below command, and use v4l2-ctl to verify the driver first.
sudo su
cd /sys/kernel/debug/dynamic_debug/
echo file csi2_fops.c +p > control

v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=3
  • please check below
please review the configuration of "line_length" in sensor driver
try to increase the delay between video lines data send via CSI
review the sensor datasheet to check the settings of FPS range



TX2

  • if you saw below message it could be the sensor output embedded data line but DT didn't declare embedded_metadata_height or it value is 0
arm-smmu 12000000.iommu: Unhandled context fault: iova=0x00000000, fsynr=0x200011, cb=19, sid=4(0x4 - VI), pgd=0, pud=0, pmd=0, pte=0


Steps to enable more debug messages

  • To enable trace for more information
echo 1 > /sys/kernel/debug/tracing/tracing_on
echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/tegra_rtcpu/enable
echo 1 > /sys/kernel/debug/tracing/events/freertos/enable
echo 2 > /sys/kernel/debug/camrtc/log-level
echo > /sys/kernel/debug/tracing/trace
cat /sys/kernel/debug/tracing/trace

The bit 22 CRC error on payload. It could be CRC error at frame end package. Please contact with sensor vendor to check the CRC header.

It could be the pix_clk_hz in DT too small cause the ISP can't handle the input.

The bit 5 and 7 indicate lose the FE package cause the FS_FAULT

The trace show the 0x0ada0040 0x40 means CHANSEL_FAULT of PIXEL_RUNAWAY means VI receives more lines than expected. The 0xad9(2778) is the lines report from the sensor driver.

Didn't receive any package from the MIPI bus. Make sure the sensor have output data to the MIPI bus

The CSIMUX_FRAME bit 21 PH single bit error repaired. Possible the sensor didn't send the ECC package.

Can try disable the ECC check.
