Dear TI.
I have some issues.
Recently, I try to developed using the OMAP4470 Blaze Ref. board.
- Issue #1 : Ocure DSI error
- Issue #2 : Does not LVDS output signal from tc35876x.
[Enviroment]
- Jelly Bean (4AJ.1.1)
- Display strucutre : OMAP4470 MIPI(DSI) input -- [TC358765] -- LVDS output -- Himex 7816 / 7318 display
- Himex Display Resolution : WXGA-1366*768 (24bit)
- DSI lane : 3 Lane (1 clock, 2 data)
