The hardware connection has been verified by imx219, and the device tree has also been rewritten based on the successful verification of imx219.
Jetson originally did not support mono 10, but has loaded the mono10 driver.
hello venceplace,
it looks you’ve incorrect port bindings.port-index = <0> for CSI/VI/Sensor.
Thank you for JeerryChang reply. When I tested imx219, I used csi0 but selected port-index=1, which can work normally. After both imx219 and sc132gs were changed to 0, imx219 can work normally, but sc132gs keeps reporting errors.trace.200.log (12.8 MB)

hello venceplace,
is it Orin Nano DevKit?
please refer to Jetson Orin Nano Developer Kit Carrier Board Specification for reference.
It is not DevKit. It is a self-developed board based on the previous nx Devkit. It is connected to CSI0 and CSIA.
hello venceplace,
you may double check the board schematic,Topic 318537 for an example to debug discarding frame corr_err messages.
36.4.3的源码中已经将
frame_err = true打开了，请问如何确认这个是否正确被打开了，另外我重新采购了一块C1901的板卡来调试还是出现一样的错误。请问这个需要从哪里调试。

咨询一下上述三个CHANSEL_FAULT是什么原因导致的。
hello venceplace,
CHANSEL_FAULT channel:0x23 frame:89 vi_tstamp:298994746496 data:0x00000000000002000x200 means.. A line ends with fewer pixels than expected. (but, it’s not reporting how many is expected).
CHANSEL_FAULT channel:0x23 frame:89 vi_tstamp:299009732288 data:0x00000000043702020x437 it’s the current line in frame, which is 1079-lines. however.. the next CHANSEL_FAULT it shows 0x438, which has additional line reported.
sc132gs 的分辨率为1080 * 1280(宽为1080，高为1280),但是gst-launch-1.0和v4l2都不支持这个分辨率的读写，请问有什么办法读出这个尺寸的摄像头数据吗？
我该如何配置才能使用如图中红色方框的分辨率读取摄像头中的数据。
hello venceplace,
may I know what did you meant it’s not supported with gst-launch-1.0 and v4l2?
please refer to developer guide for the Device Properties section.use_sensor_mode_id to select a specific sensor mode.--set-ctrl sensor_mode=Xfor mode selection.$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1280,height=720,pixelformat=RG10 --set-ctrl bypass_mode=0 --set-ctrl sensor_mode=4 --stream-mmap --stream-count=100
设备树设置的分辨率为1080 * 1280，然后只有一个mode就是mode0，附带设备树文件。tegra234-p3767-camera-p3768-cssc132-B.txt (5.6 KB)
sensor文件中提到的分辨率是这样说的
我理解是宽为1080，高为1280。然后我试过nvarguscamerasrc，nvv4l2camerasrc,v4l2src 等插件都无法正常读取BG10的视频流。
hello venceplace,
what’s the sensor mode definition within your sensor driver?camera_common_frmfmt definition of your mode table.
static const struct camera_common_frmfmt imx274_frmfmt[] = {
{{3840, 2160}, imx274_60_fr, 1, 0, IMX274_MODE_3840X2160},
{{1920, 1080}, imx274_60_fr, 1, 0, IMX274_MODE_1920X1080},
{{3856, 4448}, imx274_30_fr, 1, 1, IMX274_MODE_3840X2160_DOL_30FPS},
{{1936, 2264}, imx274_60_fr, 1, 1, IMX274_MODE_1920X1080_DOL_60FPS},
trace.6.27.log (872.6 KB)
hello venceplace,
that’s correct.CHANSEL_PXL_SOF/CHANSEL_PXL_EOF to indicate a frame has detected by VI engine. afterwards, it’s ATOMP_FRAME_DONE to indicate it’s complete writing a frame to memory.
please check v4l utility for fetching the frames.$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100
