Part Number: DLPC3433

Hello,

I'd like to know what is the problem.
I made to send from Qualcomm AP to DLPC3433 for MIPI DSI communication like below.

0x1A 0x01
0xD7 0x00
0x10 0x00 0x00 0x00 0x00 0x00 0x05 0XD0 0X02
0x12 0x00 0x00 0x00 0x00 0x00 0x05 0XD0 0X02
0x2E 0x00 0x05 0xD0 0x02
0xBD 0xDF 0x00
0x07 0x00
0x05 0x00
0x1A 0x00

But the DLP displays default splash.
What should I check next.

Best Regards.

Yeon.
