using DLPC6401 to do. 45 1080P DLP projector, the main platform using RK3128, currently encounter a use problem as follows: Please help see if there is any solution.
1、Turn on the initial configuration screen rotation has no effect：
The boot directly configures 0X08 and 0X09 registers. Screen rotation is ineffective. We must first configure 0X00 for 1 and delay 200 ms , then 0 X00 for 0 and delay 300 ms, then 0X08 and 0X09 will be effective. But this configuration register will appear a result, that is, the boot rotation screen will encounter: Logo screen, to the test screen, then to the Logo screen, so as to affect the user experience effect, is there any way to initialize the boot rotation has been a Logo screen?
2. Start-up initialization configuration brightness 0Xcb register is not effective, need to boot 30 seconds (Android system boot), in the configuration of 0Xcb register will be effective, can you achieve boot-up configuration register brightness configuration?
