Hello support,
I allow myself to contact you because I encounter an integration problem with TC358743 bridge (bridge device that converts HDMI stream to MIPI CSI-2 TX).
Before contacting you, I took care to check my “integration” as you describe in the documentation (Tegra Linux Driver Package Development Guide/camera_dev.html).
I encounter the following error: (from vi2_fops.c)
[ 65.086547] video4linux video0: frame start syncpt timeout!0
[ 65.092881] video4linux video0: TEGRA_VI_CSI_ERROR_STATUS 0x00000000
- Driver integration
My kernel: 4.9.253-tegra (branch l4t-r32.7.1)
According to documentation, I added in drivers/media/i2c/tc358743:
/* frame format */
static const struct camera_common_frmfmt tc358743_frmfmt[] = {
{{1280, 720}, tc358743_30_60fps, 3, 0, tc358743_MODE_1280X720},
{{1920, 1080}, tc358743_30_60fps, 3, 0, tc358743_MODE_1920X1080},
};
and I use:
sd->entity.ops = &tc358743_media_ops;
state->pad.flags = MEDIA_PAD_FL_SOURCE;
err = tegra_media_entity_init(&sd->entity, 1, &state->pad, true, true);
if (err < 0)
goto err_hdl;
etc…
And I looked at your examples, such as:
kernel/nvdia/drivers/media/{imx185.c, imx185_v1.c or tc358840.c}
My dtsi file (tegra210-tc358743.dtsi (4.6 KB))

- Test environment:
For testing, I used a Jetson Nanodev kit and a TC358743 kit before switching to my hardware soon.
The geekworm’s card is functional with a PI3 but no with a Nano.
Here are some elements to help you understand the problem:
