<p><b>New page</b></p><div>I am trying to capture HDMI video from a TC358743 (C790 board) connected to a Raspberry Pi 5 running Linux kernel 6.12.25. The HDMI source is 1920×1080 @ 60Hz. EDID writing and media-ctl link configuration were completed as described in the documentation.<br />
<br />
Multiple /dev/video* nodes are present, including /dev/video0 and /dev/video4.<br />
I can set formats (e.g., RG16, BYR2) using v4l2-ctl on /dev/video0, but attempting to stream results in:<br />
<br />
VIDIOC_STREAMON: Invalid argument<br />
<br />
Even OpenCV and ffplay fail to read frames.<br />
<br />
Current configuration:<br />
• EDID written via /dev/v4l-subdev2 using v4l2-ctl –set-edid<br />
• Link configuration via media-ctl:<br />
tc358743 11-000f:0 -> csi2:0<br />
csi2:4 -> rp1-cfe-csi2_ch0:0<br />
rp1-cfe-csi2_ch0:0 -> pisp-fe:0<br />
pisp-fe:2 -> rp1-cfe-fe_image0:0<br />
• /dev/video0 supports RG16, BYR2, etc., but none work in practice<br />
<br />
Questions:<br />
1. Has anyone successfully used this board with Raspberry Pi 5 and captured video?<br />
2. Which /dev/videoX node and pixel format (pixelformat) were used?<br />
3. Is additional configuration required beyond EDID and media-ctl?<br />
4. Is /dev/video0 (from rp1-cfe-csi2_ch0) the correct device to use?<br />
5. What are common causes of “VIDIOC_STREAMON: Invalid argument” with TC358743?<br />
<br />
Any advice would be greatly appreciated. Thank you.<!-- migrated from Comments; original IP: 27.143.28.50 --></div>27.143.28.50
