Dear TI team,

Thanks for providing the quick support for the previous query.

URL: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1038168/ds90ub941as-q1-issue-in-configuring-and-verifying-pattern-generation-ds90ub941as-q1------ds90ub948-q1?ReplyFilter=Answers&ReplySortBy=Answers&ReplySortOrder=Descending

Continuing to the above ticket, we are trying to display some pictures (.png, ,jpg etc) onto the LVDS Display using weston library and tried the same with drm-frambuffer application.

Reference link : https://embear.ch/blog/drm-framebuffer

But the image quality is not good.

Attaching the register dump for the serializer (DS90UB941AS-Q1)and De-serializer(DS90UB948-Q1)

And target board console and modetest patterens are perfect. Attaching the reference images

While trying with weston library to render an image onto the Display through DRM framework where the TI FPDlink-III bridge drivers will come into picture.

Reference for the bridge drivers is https://lists.freedesktop.org/archives/dri-devel/2019-March/210542.html

Attaching the original and processed image for your reference.

Is there any any registers (related to DSI clock) need to be updated at serializer or De-serializer?

Please help us to get the image quality.

Hi,

Thanks for your question. Can you provide schematics of 941 and 948?

Are you able to get patgen successfully working with internal or external (non-DSI) clock? If DSI input clock jitter tolerance does not meet requiremnts then sometimes images can become abnormal.

Please give me a day to take a closer look at your register dumps to see if anything looks suspect.

Regards,

Logan

Hi,

Thanks a lot for immediate response.

As of now, we are using the internal clock source. And pattern generation from serializer using patgen registers is verified and working as expected.

Best Regards,

Hi Saikrishna,

I'm still investigating this. I'll get initial feedback to you by Monday.

HI Saikrishna,

Can you provide any initialization scripts used for 941 and 948? Also can you share the schematics?

Can you provide a register dump of the DSI indirect page?

Do you have a DSI packet analyzer to verify the output of Weston/DRM? Can you verify DSI jitter based on this guide? If patgen is working correctly, then it could be something specifically with the DSI.

The recommended 941 bring-up flow and debug process can be found in this bring up guide.

Configuration & Status Registes:

Reg 0x4F: Continuous Clock Mode, 4 lanes

Reg 0x56: DSI Reference Clock Mode

Reg 0x5A: 0xC9 11001001b

DSI CLK Detect: 1
No DSI CLK: 0
Freq Stable: 1

Based on above registers, it seems as if DSI clock mode is being used instead of internal clock.

Regards,

Logan

Hi Logan,

Thanks for the reply.

The below is the register config initilization script for 941. <reg-addr> <reg-value>

reg_config_941 = 0x01 0x08 0x1E 0x01 0x03 0x9A 0x1E 0x01 0x40 0x05 0x41 0x21 0x42 0x60 0x1E 0x01 0x5B 0x03 0x4F 0x8C
0x1E 0x01 0x40 0x04 0x41 0x05 0x42 0x1E 0x03 0x9A 0x01 0x08 0x17 0x9E 0x01 0x00

The below is the register config initilization script for 948. <reg-addr> <reg-value>

reg_config = <0x20 0x90>

We will get confirmation from our customer to share the schematic and then will share with you soon.

We are working on the DSI indirect register dump. And will provide you soon.

We do not have any DSI packet analyzer available in our office to verify the DSI frames and CLK jitters.

As per the comment on the previous reply, DSI clk is being used as a reference clk for serializer. Is that good enough to get the proper Display content?

Among the 3 clock modes(DSI CLK, Internal and External), which one is more preferable to configuration in order to get good Display quality ?

As per the customer, we can not share the schematic in public forum.

saikrishna.gangavarapu@embitel.com is my mail ID. Can you please send a HELLO mail to this. Then I can share the schematic through the mail.

Hi Logan. Thanks for sharing the mail ID.

We are also in contact with Display Vendor, and as per them the incoming data for the LVDS Display must be in VESA format.

Does the serializer or De-serializer will have any control on these formats(VESA, JEIDA, RGB)? If YES, How to configure?

Right now, MIPI-DSI data is in RGB24 bit format.

As of now we configured as 2-lane FPD-Link III input, Dual-link openLDI output configuration. In this case will serializer and De-serializer pair will take care of the splitting ( one port of LVDS Display is 960X720 and the other is 960X720 and clk is also provided for only one port) the data which is being sent as Full resolution (1920X720)?

Thanks and Regards,

Hi Saikrishna,

Depends on a few things, but typically external clock can provide the best jitter and accuracy especially at higher PCLK rates sometimes the DSI can have a hard time meeting jitter targets.

If you can, it might be good for you to verify the DSI clock jitter and timing requirements with this guide: [FAQ] DS90UB941AS-Q1: DSI or REFCLK Jitter Measurement. It should only use a oscilloscope to measure if you have available.

Saikrishna Gangavarapu said:

Right now, MIPI-DSI data is in RGB24 bit format.

Color and bit mappings can be found on pages 43-48 of the datasheet. RGD24 bit is supported. Does your MAP_SEL setting match the panel configuration? If you are able to get patgen, I'd not worry about the panel compatibility.

Do you have the 941 scripts in address/data format? Also, if you can share the indirect pages as well that will rule out any DSI settings that could be impacting the screen.

Regards,

Logan

Hi Logan,

Thanks a lot for the clarification and inputs.

We will get back to you with all the information (DSI indirect registers, MAP_SEL setting, etc) required to you to rule out a few suspicious factors from our Debugging prospective

For your information, we are Custom Linux OS with i2c command line utilities to configure serializer and De-serializer. Not using ALP tool.

MAP_SEL is selected for Dual OLDI output configuration.

As you mentioned in the previous comments about the clocks. We are planning to use external clock. we have configured 0x56 with a value of 0x01. But nothing has come on the display. we have also tried with the value of 0x03 for 0x56 register but could not get any content on the Display.

Even when we configure for internal clock (0x01 value to 0x56 reg), No content on the screen.

Do we need to set any other configurations to setup internal/external clock settings?

Thanks and Regards,

Saikrishna
