I need help. Using the DLPDLCR2000EVM, it is found that the projection projects the flower screen state, as shown in the following figure. However, entering the Debian system through the putty serial port can be entered normally. First burn a picture to the system, by entering fbi, the image is cast using the projection, and there will be:using "DejaVu Sans Mono-16", pixelsize=16.67 file=/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf
Theoretically, the dlp projection at this time can still cast the pictures I need, but the dlp projection is still in the flower screen state. I don't know what the reason is, I hope someone will come and help solve it.
Please following the user guide:
Page 15, the 2 keypoints: 1. external video, resolution is nHD(640×360).
i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i

Hello, this method still does not work, the effect of the projector is still the same, just use the method you said to configure, and then use:
As a result, the projection screen flickered and disappeared, and is still a split-screen.
Please check the posts:
If it still didn't work, then need to measure the signals: VSYNC, HSYNC, PCLK.
Hello, I used the method you provided, and found that the projection phenomenon is still unchanged. Now I turn on the power, but I can't even enter the system through the projection, and the projection is always in a flowered state. So is there any other way, if necessary, you can do it remotely.
DLP projector can work well. This should be your front end Debian system settings. Please check with your Debian system board supplier.
And post your requests on https://e2e.ti.com/support/dlp-products-group/.
And contact your local TI office engineers.
Thanks & Best Regards,
Now it's the DLP that doesn't work.I tried so many ways to project it, but it didn't work.
If DLP can't project any image, please check the schematic: https://www.ti.com/lit/pdf/tidrs01
1. proj_on HIGH
2. parkz, resetz: HIGH;
3. P1P8V, P1P0V;
5. Then check XD100 Frequency.
I checked it out and thought that the projection should be broken. Can I apply for repair.
