Part Number: SN65DSI83-Q1
I had use the SN65DSI83 on Qualcomm msm8909 platform（Android5.1）, and the SN65DSI83 i2c work normal. I debug the chip on test mode, and the screen was black, the attachment was the LCD datasheet. My DSI CLK is 429MHz, and I divided by 6, the LVDS CLK is 71.5MHz
1. The EN input of SN65DSI83-Q1is pulled high by msm8909 after power-up.
2. SN65DIS83 is i2c configuration, set it to test-pattern mode, the specific settings are as follows:
3. msm8909 DSI driver load, mipi output clock through the oscilloscope as follows:
But screen did not work，I have some question：
1. Is the dis-continuous mipi clock Normal above the picture?
2. The table is the initialization sequence described in the sn65dsi83 documentation. How to set up LP11？
In reply to Nizq Rex:
It is required by the MIPI spec for the processor to drive DSI outputs to LP11 prior to the transition to the HS mode. The initialization/transition sequence requirement is per the MIPI DPHY version 1.0.0 (Section 6.11) and DSI version 1.02.0 (Section 5.7) specification requirements. If DSI interface is driven to illegal states/protocol by the host, the SN65DSI8x may get into undesirable states.
