Hello,

Looks like you are using v7.4.2. Can you please confirm if any changes have been made to the firmware? Could you also provide a detailed description of the issue? If you are referring to the black and white vertical bar issue, this is usually causes when in external video mode without providing some time of video data. 

Please also see our hardware diagnostic tool to help debug (TI DLP Pico Hardware Diagnostic Tool).

I can't seem to download it.  The firmware was given to me by ANHUA.

Hello, 

Did you fill out the export control form it asks before downloading? Can you also please provide the previously requested details?

Best,

Max

Yes, I did. Mostly names, companies and military entities.I just got customer service working on it.

Hello,

I need details regarding the issue that is being reported, please describe what issue you are facing and the steps to reproduce it.

Best,

Max

I kind of forgot. How can I reapply

Hello,

I think there might be some confusion, I am referring to the issue originally reported with the DLP system.

Best,

Max

Our projection occasionally appears the problem of flower screen and stuck in the first frame.

I tested that the mipi signal was transmitting at the time.

Please provide the steps/commands you send to setup the video and reproduce this issue.

Hello Maximus,

ok,I'll send it to the office tomorrow.

I downloaded it now TI DLP Pico Hardware Diagnostic Tool.  

What tool do I need to connect my hardware diagnostic tool to DLP technology controller, i2c to usb tool?

SCL, SDA, 3.3V and GND pins  Which pins to connect to DLPC3432?

Hello,

We recommend a DeVaSys, USB2ANY, or Cypress device.

Max

SCL, SDA, 3.3V and GND pins  Which pins to connect to DLPC3432?

Hello，

         have no USBANY in my hand for the time being. First, I use the usb of CH341 to transfer to i2c, which cannot be connected to the i2c interface

Hello，

        I found that a step on the mipi input side would break the screen, disconnect the resistance between DLPC3432 and mipi, and found that DLPC3432 would raise when started

Hello,

Have you resolved this issue then? 

Best,

Max

No. Could you please help me figure out how to solve this problem?

Hello,

        We are configured according to this file, and now the probabilistic flower screen, how can I reverse prove that there is a problem with my previous DSI setting.

Hello,

We are not DSI experts, all I can suggest is ensuring the DLPC DSI spec is followed and setup according to the guides I have provided you. Do you have any additional information on when this behavior is observed? Do you ever see a stable/clean image via DSI?

Best,

Max 

Hello，

         We changed the timing and it's working normally, thank you！
