Hello. I am new in android building and studying about 3 months. I am porting new 1.4inch mipi lcd driver on banana Pi M64 board and android 6.0.1 current symtom is not displaying just white screen in boot, but working after screen off and on with pressing power key two times in idle state.
I am doubt to pwm control for lcd elvss power level. target voltage is -2.4v under but -1.5v in booting. -3.4V after screen off and on. lcd compile option has module S070WV20_MIPI_RGB name. so I have changed drivers/video/sunxi/disp2/disp/lcd/S070WV20_MIPI_RGB.c file in the linux lcd kernel. but not work. it seems this code is not applied in boot process. because There is no any change or log when I changed LCD_Power_on or LCD_Panel_init code. someone says initial boot code and kernel code is different. if somebody knows where lcd initial code or any configuration is, let me know it. any guide or experience is ok. Thank you in advance. -- -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting --- You received this message because you are subscribed to the Google Groups "android-porting" group.
