AM67: AM67x work with DSI to HDMI bridge

Rich Chen

Part Number: AM67
Other Parts Discussed in Thread: AB15

Tool/software:

Dear champ,

My customer is working on AM67x platform with Lontium LT9611UXD which is DSI to HDMI bridge.

Lontium provide a driver (file.zip) and dts file https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/lontium_5F00_lt9611ex.dts0880.file.zip

TIDSS driver can be loaded normally but DSI has no signal output.

There is no output from LT9611UXD either.

Here is the demsg log below.

Could you take a look which part may be missing for DSI to output signals?

Hi Rich,

Looks like framebuffer is created and EDID from monitor is obtained. Software-wise, it looks mostly set up.

Can you share the logs from the following commands:

kmsprint
modetest -M tidss

Regards,

Takuma

Hi,

Those logs all look good. It seems software-wise, display driver is functional. We will now go through troubleshooting similar to what we did here: https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1456851/processor-sdk-am67-dts-configuration-for-dsi-convert-to-hdmi?pifragment-327888=1#5758752

So as a first question, have you physically measured the clock lines to see if clock is coming out of DSI?

Regards,

Takuma

Takuma,

Yes, customer did measure the DSI clock line and see no clock output.

What troubleshoot do you mean, that e2e you pointed to is the case for same customer before changing DSI to HDMI bridge.

In the case, we can see DSI clock after setting overlay to Raspberry pi 7" panel.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Without enable DT overlay, there is no DSI clock output.

After enable DT overlay to k3-am62p5-sk-dsi-rpi-7inch-panel.dtbo, customer see DSI clock output but there is no signal on data pairs.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Does Lontium DRM driver set the device tree right to output DSI to Lontium bridge chip?

Hi Rich,

Troubleshooting by looking through different registers to see if there is an error reported in status registers.

Can you check if SoC is reporting errors by running "devmem2 0x305000F0", similar to other thread?

Hi takuma,

when I setup modetest -M tidss -s 41@39:1920x1080-60 modetest -M tidss -s 41@39:800x600-60 , DSI data not output, but setup modetest -M tidss -s 41@39:640x480-66 , DSI havs data output, it seem that in the some config, DSI have data out, can you have some suggest?

Hi,

Can you share the status register value for both the cases where DSI has data output and DSI has no data output? It should tell what is wrong.

Hi,

Thanks for running the command. So, as expected, it looks like 640x480 the DSI register is reporting that it is running fine. However, 1920x1080 is reporting a ERR_MISSING_HSYNC.

Can you do a "modetest -M tidss" again, but run this when 640x480 resolution is used? The idea is to collect the timing parameter information that works, so that you can compare with the timing parameter used for 1920x1080.

Regards,

Takuma

Takuma,

I do have question to confirm for status register which I am still confused on this status register.

How and why ERROR will be occur if this register is about DSI output?

DSI supports all output and with or without connected device behind should have not possible to feedback to DSI controller.

I look into TRM and I wonder if the status register error is about the signals from DPI interface to VSG with error but not actually the device behind DSI output?

Hi Rich,

Rich Chen said:
How and why ERROR will be occur if this register is about DSI output?

MIPI PHY itself has logic to report some error. Below is a screenshot from the "MIPI Alliance Specification for Display Serial Interface (DSI), v1.3.2" from the MIPI organization. Lane 0 can report back an error since it is a bidirectional signal during LP mode, which DSI can go into LP mode during blanking periods.

Bottom line is that DSI can report back error, and for more specific information, please read the specification.

Regards,

Takuma

As for next experiments, could you try to select this mode line? Essentially, try testing any of the other negative sync mode lines.

Please be aware that I see another 1024x768 that is using positive sync, so you would need to select the mode by index instead of resolution. Something like below:

modetest -M tidss -s 41@39:#8

Lontium asks what our MIPI byteclk is?

Could you comment?

Hi Rich,

In DSI domain, we move from pixel clock to byte clock. We are using RGB888, which is 24 bits per pixel or 3 bytes.

So 65000kHz * 3 will be the byte clock for 1024x768. 31500kHz * 3 for 640x480.

Takuma

Takuma,

Thanks, I discussed with Lontium support team on the Hsync missing error reported on AM67x DSI status register, Lontium mentioned that there is MCU inside LT9611UXD and it can initial bridge itself.

Also, the data on Lane0 will be single direction on Lontium bridge and it is not bidirectional which means BTA (Bus Turn-Around) and BTR (Bus Turn-Around Read) is not supported.

LT9611UXD supports only video mode and it will not response to commend mode according to the discussion.

Therefore, Lontium suggest skipping initialization of LT9611UXD and turn off BTA then focus DSI output in video mode (1080p60 or 720P60).

Below are the timing which LT9611UXD firmware currently supported.

DSI 4 lanes and clock 1 lane, color format can be accommodate automatically.

Bases on such condition, could you provide a configuration to output 1080p60 as DSI video mode with the timing match to LT9611UXD can support?

We need first have LT9611UXD get input from AM67x to make sure connections.

Hi Rich,

Rich Chen said:

These should be configurable from Lontium's bridge driver using the DSI flags.

Rich Chen said:

As for timing parameters, these are auto-populated based off of connected HDMI display. You can force a specific timing parameter by deleting other possible timing parameters from the drm_edid.c. As an example that forces 640x480 at 60Hz, below is a hack that deletes all the other DMT modes within drm_edid.c:

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/0007_2D00_drm_2D00_edid_2D00_Add_2D00_custom_2D00_DMT_2D00_modes.patch

You can define the timing parameters supported by the Lontium bridge and delete the other timings to experiment with the different parameters.

Takuma

Takuma,

The patch and hack provided for LT8912b looks different from current DRM driver so customer cannot find corresponding place to modify.

However, now we find only one setting #0x10 1024x768 60Hz can output successfully. (Status Register is 0x1)

modetest -M tidss -s 41@39:1024x768-60

All other resolution setting cannot output data (0nly clock, status Register is 0x4).

On Lontium debug console, it can detect 1024x768 input but the output cannot be locked so it cannot output to HDMI. We don't know exactly the reason why it cannot be locked.

Lontium asks to increase MIPI clock 10%, is this feasible?

For the patch 0001 you provide to change Postive Sync to Negative Sync, current LT9611 driver is different from LT8912b which we can not find corresponding place to modify or make similar change in DRM driver or Lontium driver.

Now our goal is to output 1920x1080p and status register can be 0x1 without error.

We have not identified the reason why Hsync error will occur but we have not change positive Sync to negative Sync. We will keep checking this in code.

Hi Rich,

The reason why 1024x768-60 worked is because it is using negative vsync and negative hsync. Below is from modeset output that customer had shared:

#8 1024x768 60.00 1024 1048 1184 1344 768 771 777 806 65000 flags: nhsync, nvsync; type: driver

Your customer has said 640x480 also worked, which is also negative vync and hsync.

Rich Chen said:
For the patch 0001 you provide to change Postive Sync to Negative Sync, current LT9611 driver is different from LT8912b which we can not find corresponding place to modify or make similar change in DRM driver or Lontium driver.

I would assume changes would be in lt9611uxc_video_setup. This is Lontium specific code to program the registers in the bridge hardware itself, so TI will not be able to help. But, the LT8912B driver can be used as reference.

Rich Chen said:
Now our goal is to output 1920x1080p and status register can be 0x1 without error.

Patch 7 will attempt to force 640x480 with negative vsync and negative hsync by deleting all other DMT modes. A similar thing can be done for 1920x1080 to output negative vsync and hsync.

Takuma,

In Patch 7, it changes 800x600 and 1280x1024 from PHSYNC and PVSYNC to NHSYNC and NVSYNC.

However, patch 1 for LT8912b.c cannot be used directly to LT9611UXD since the driver LT9611UXD_main.C changes a lot so it cannot be hacked as this patch.

LT9611UXD driver is attached here. Could you check how to apply same change onto it?

0513.file.zip

Secondary, we were able to output 1024x768 or 800x600 (could depend on different HDMI monitor is used) onto LT9611UXD but it cannot be "locked" and send out HDMI display.

Lontium asked to increase MIPI clock by 10% as test.

You answered the MIPI clock rate is multiple pixel clock, how to change MIPI byte clock without change pixel clock?

Because changing pixel clock will change the FPS of output in same resolution, can we increase MIPI clock only by 10% in our DSI output? and where to modify?

"In DSI domain, we move from pixel clock to byte clock. We are using RGB888, which is 24 bits per pixel or 3 bytes. "

Please advise.

Hi Rich,

Changes will be in lt9611ex_bridge_mode_set function. Specific change will be a register write to the lt9611ex bridge to set negative syncs. TI cannot help with creating the actual patch, because we do not have access to datasheet and inner workings of the lt9611ex bridge from Lontium to know which registers control the sync flags. Please have Lontium guide the customer to help.

No, we do not recommend changing just the byte clock. In DSI driver, byte clock/bit clock (hs_clk_rate) is calculated from the pixel clock. My previous calculations may be slightly misleading if those are the cause of concern, because byte clock is a function of pixel clock, number of bits per pixel (bpp), and data lanes. The number of data lanes were not considered in my previous calculations I shared, so the calculation would be correct for a 1 lane DSI configuration.

In any case, you could try to experiment with cdns-dsi-core.c and the hs_clk_rate set in cdns_dsi_adjust_phy_configs, but I do not recommend changing around with the timings in this DSI driver since these timings are field tested and generally stable.

Takuma

Takuma,

We got no progress on modifying hs_clk_rate.

Currently, the implementation is try to add Lontium LT9611 as bridge and final output is HDMI.

EDID will be read and negotiate with controller to determine which resolution to output.

Now we would like to not consider bridge and force AM67x DSI output signals like to connect to a DSI panel.

First, we will disconnect LT9611 then try to output 1920x1080 60Hz video mode signals on DSI make sure we can sent out and see if it can be output directly without Lontium chip.

Then we will reconnect LT9611 to make sure whether connecting LT9611 will cause VSG stop.

We originally want to use Raspberry Pi 7" setting .dtso but found not sure how to set the resolution for panel.

Could you create a patch for panel mode and output 1920x1080 60Hz? Not to use bridge output. We want force DSI output directly without reading EDID and output HDMI.

Lontium bridge can convert to HDMI as long as DSI can send current signals to them.

Hi Rich,

I will work on a patch to see if I can output 1920x1080. However, this will take time.

In the meantime, please work with customer/Lontium to root cause why the 1024x768 resolution is not outputting to HDMI. SoC is outputting to bridge in 1024x768 case, so this can be used to unblock customer development team's debug.

Takuma
