AM67: No video data to MIPI DSI display

Nathan Morrisson

Part Number: AM67

Tool/software:

Hello,
I am working on getting a new MIPI DSI display working with a custom board using the AM67. Our software is based on the ti-linux-kernel 11.01.02 tag, v6.12.33, with the addition of this patch stack https://lore.kernel.org/dri-devel/20250414-cdns-dsi-impro-v3-0-4e52551d4f07@ideasonboard.com/. There is no driver for this specific panel so we have been modifying another MIPI DSI driver to work with this display. Currently we get no video output on the display. We have been able to probe the clock and the data 0 lane and we are able to see the clock and the initialization sequence commands being sent in low power mode. The initialization sequence for this panel is a DCS 0x11 command then a DCS 0x29 command. Here is an image of part of the data capture from data 0 during the initialization sequence (channel 2 in blue):

After the initialization sequence is done, we do not see anymore data but the clock continues.

We also used kmsgrab to see what was in the frame buffer, and it is the image we expect to see. We do not see video data being sent to the display at any point. What could be preventing the driver from ever sending the video data to the panel?

Regards,
Nathan

Hi Nathan,

The assigned expert is currently out of office, returning on 30th June. Please expect a delay in responses.

Hi Nathan,

Apologies for the delay.

As a first step, can you check if SoC is reporting errors by running "devmem2 0x305000F0"?

Below is what each non-reserved bit in that register should mean. Value should be 0x1 if no errors.

10	VSG_RECOVERY
9	ERR_VRS_WRONG_LENGTH
8	ERR_LONGREAD
7	ERR_LINEWRITE
6	ERR_BURSTWRITE
5	REG_ERR_SMALL_HEIGHT
4	REG_ERR_SMALL_LENGTH
3	ERR_MISSING_VSYNC
2	ERR_MISSING_HSYNC
1	ERR_MISSING_DATA
0	VSG_RUNNING

Regards,

Takuma

Nathan is out of office this week, but I have a copy of the SW and hardware we are testing with.

Running the devmem command gives a read of 0x00000004, which according to your chart would be a REG_ERR_SMALL_LENGTH error, correct?

I won't be able to answer any of the more SW oriented questions, so any of those will have to wait for Nathan to return, but I can possibly help out with HW related questions.

TI__Guru 51053 points

Hi Christyan,

0x4 would mean that bit 2 is set, meaning ERR_MISSING_HSYNC. This can be caused by timing parameter issues. The behavior described in original post aligns with the error, since hsync error will occur after sending one line of the frame.

Can you collect the timing parameter information by running "modetest -M tidss" and share the resulting logs?

Regards,

Takuma

Hi Nathan,

Please comment if any of the following sounds unexpected.

DSI looks to be connected to a DSI to HDMI bridge. And HDMI connector does not have a display connected
The bridge/HDMI is getting a mode to connect to a 1200 width x 1920 height 60FPS monitor (instead of a 1920x1200 monitor)

Point 2 is a bit suspicious. 1200x1920 resolution is quite rare compared to 1920x1200. Please confirm if both points are expected.

Regards,

Takuma

Hi Takuma,

1. There is no DSI to HDMI bridge in our design. We do have HDMI on our board but that should have nothing to do with DSI. Is it possible that the modetest command is just listing the two devices without them being connected?

2. The timings we got from the display manufacturer are 1200x1920, but I tried swapping to 1920x1200 and now I am getting an output of 0x1 when reading from 0x305000F0, but there is still nothing on the display.

Regards,

Nathan

TI__Guru 51053 points

Hi Nathan,

There should be a DSI interface under "Connectors" if DSI is being initialized. If there is no DSI connector, it looks like there was an issue during initialization.

0x1 from 0x305000F0 is good. It means it is running.

As a next step, can you share the full boot logs from "dmesg" to see if there are any logs related to DSI?

Regards,

Takuma

Hi Nathan,

Looks like DSI panel driver is being probed, so a bit strange why DSI interface does not seem to enumerate under modetest.

Can you share the devicetree (if whole devicetree is non-shareable, just the display related devicetree nodes are sufficient), so that I can review how the display pipeline is connected?

Regards,

Takuma

Hi Nathan,

Thanks for the dts. lts,lts-lcd282 <- you mentioned a MIPI DSI driver was referenced for this new panel driver. Could you share which driver was referenced?

I have seen developers use the panel-simple.c driver for simple screens, but I do see that there are some unused touch_screen_pins_default defined in shared dts.

Regards,

Takuma

Hi Takuma,

Sorry about the unused touchscreen pins in the device tree, I had touchscreen support in the device tree at one point but pulled it out since it does not affect the function of the display. Currently we are using a custom driver from the display manufacturer that I have modified to work with our hardware.

A few things are commented out, particularly the lines related to the reset and backlight GPIOs as these are tied to the global reset on our board and therefore not necessary in the driver.

I also previously tried using the panel-simple driver for this display and got the same result as with this driver.

Hi Nathan,

Nothing stands out in the driver other than the backlight related logic, which should be fine to remove based on your input.

Two things:

With the 1920x1200 timings, you mentioned the status register outputs 0x1. Do you see signals on the scope?
Can you remove HDMI node from the devicetree, and re-run "modetest -M tidss"?

Regards,

Takuma

Hi Takuma,

Thanks for checking out the driver.

1. With the 1920x1200 timings we see the same initialization data as before, and now we also see what appears to be image data. Here is an image of the new data we are seeing:

There is still no output on the display though, and the display manufacturer confirmed that 1200x1920 is the correct resolution for this display.

2. Here is the output from modetest with the HDMI removed from the devicetree:

Hi Nathan,

Nathan Morrisson said:
Here is the output from modetest with the HDMI removed from the devicetree:

Yes, this looks more like the expected output.

Nathan Morrisson said:
There is still no output on the display though, and the display manufacturer confirmed that 1200x1920 is the correct resolution for this display.

Could you change it back to the 1200x1920 and re-run the "modetest -M tidss" again? I expect timing parameters to be quite different.

Regards,

Takuma

Hi Nathan,

Where are these timing parameters obtained from? Is this from manufacturer for 1200x1920 resolution?

These are not part of the DMT standards, and I do not think these are following CVT standards as well.

Takuma

Hi Takuma,

These timings are directly from the display manufacturer for our panel.

Hi Nathan,

As an experiment, can you try defining some negative sync flags like this:

.flags = DRM_MODE_FLAG_NVSYNC | DRM_MODE_FLAG_NHSYNC

If above does not work, let's experiment with the timing parameters. I am thinking about plugging in some numbers from this video timing parameter calculator I found online: https://tomverbeure.github.io/video_timings_calculator

Takuma

Hi Takuma,

I believe we have fixed the issue at this point. What ended up working was using the calculator you provided to create timings for a 1200x1920 display. We were able to get output on the display using the timings from the CVT modeline. The output was still slightly corrupted though, so I made some small adjustments until I got a good looking image. Here is the timings that I am currently using for a good output.

static const struct drm_display_mode lts_lcd282_mode = {
                .clock = 154000,
                .hdisplay = 1200,
                .hsync_start = 1259,
                .hsync_end = 1271,
                .htotal = 1295,
                .vdisplay = 1920,
                .vsync_start = 1923,
                .vsync_end = 1933,
                .vtotal = 1989,
                .flags = DRM_MODE_FLAG_NHSYNC | DRM_MODE_FLAG_PVSYNC,
};

Thanks for your support getting this issue solved.

Regards,

Nathan
