Part Number: SN65DSI84

Tool/software: Linux

Parameters of the panel:

Resolution: 1600x1200

Vertical Period: 1233

V-Blanking: 33

Horizontal Period: 880

H-Blanking: 80

Panel clock: 65.125Mhz

Test pattern shows normally but only half of the screen shows up in non-test mode.

In addition, nothing shows up if the 0x20 and 0x21 registers are set to 1600 in non-test mode, the half screen is seen when 0x20 and 0x21 registers are set to 800.

Attached are the DSI status and CSR files generated by the DSI Tuner V2.0.

What are not set properly?

Hi I.K.,

Thank you for your quick response.

The datasheet is marked as Confidential. I'm waiting for the sharing approval. I may not post it here even if I get the approval 'cause it can be seen by everyone.

Can you see my email address? If so, can you send me an email so that I send it to you directly? Or, do you have a secure FTP site that I can upload it to?

Thanks,

Steven

Closing this thread as it was resolved over email. Suspected root cause is line time mismatch.
