-
Currently using the Jetson_Linux_R36.4.3_aarch64 version, with hardware being the AGX Orin 64G version.
-
At present, all 16-lane MIPI CSI are in use. CSI-A/B and CSI-C/D are connected to an LT6911UXE chip, inputting 4K60 data using 8-lane dual-port mode, meaning 4 lanes per port, with each port transmitting 1920x2160 format data.
-
CSI-E/F and CSI-G/H are connected to another LT6911UXE chip, also inputting 4K60 data using 8-lane dual-port mode.
-
The current issue is that CSI-A/B and CSI-C/D can use gang mode stitching, but CSI-E/F and CSI-G/H cannot be stitched using gang mode, and the following error is reported.
[ 69.718144] tegra-camrtc-capture-vi tegra-capture-vi: Invalid NVCSI stream Id
[ 69.725554] tegra-camrtc-capture-vi tegra-capture-vi: Invalid NVCSI stream Id
[ 69.732944] Unable to handle kernel NULL pointer dereference at virtual address 00000000000002b8
5、 From the error, it appears that directly using id0-id3 in a gang mode-like configuration results in an error because the CSI channels are port0-7, but the stream channels are 0-5. The VI has only 6 available streams. CSI-E/F and CSI-G/H share one VI port, namely VI-4 and VI-5.
6、Does the AGX Orin platform not support gang mode stitching for CSI-E/F and CSI-G/H? We have tried modifying the tegra-camera driver, and after forcing changes to the driver, we can occasionally obtain the data stream. However, there are instances where data cannot be obtained, and kernel dumps occur sporadically. Can you confirm whether gang mode supports csi_stream_id 4 + csi_stream_id 5?

This is the log after modifying the tegra-camera driver to forcibly support gang mode stitching for stream 4 and stream 5. Occasionally, there are anomalies where the data stream cannot be obtained, and kernel dumps occur sporadically.

Currently, these parts have been modified.
1、channel.c

chan->port[i] = next_port;
dev_info(chan->vi->dev, “chan->port[%d] : %d\n”, i, chan->port[i]);

2、capture-vi.c

3. After these modifications, CSI stream 4 and stream 5 can be stitched using gang mode, but occasionally data cannot be retrieved, and kernel dumps occur sporadically. Could you confirm whether such modifications are acceptable? Has the driver been updated to support gang mode for CSI stream 4 and stream 5?
I don’t think CSI-E/F CSI-G/H can support gang mode due to this brick only support one streaming but two streaming to support gain mode.
Hello, thank you for your reply.
- Does the current version of the driver not support gang mode? Is there any new submission in the official design that allows AGX Orin CSI-E/F and CSI-G/H to support gang mode, or is it fundamentally unsupported by design?
- I have modified some of the code above, and currently, CSI-E/F and CSI-G/H can forcibly operate in gang mode to stitch and obtain a complete image, but there are occasional kernel dumps. Could you tell me how to modify the driver to support gang mode for CSI-E/F and CSI-G/H?
- If CSI-E/F and CSI-G/H do not support gang mode, is the only option to create two video nodes and perform stitching at the user level? Are there any other solutions available on Jetson?
The HW design of CSI-E/F CSI-G/H don’t support gang mode.
Thanks
