Is my V100R001C02SPC060 version of the SDK, consult https://blog.csdn.net/weixin_36704535/article/details/78581291 this article writes the LOGO files to burn spi nor Flash,
Change my this statement:
Run_command (" startvo 0 32 12 ", 1);=="run_command (" startvo 52 12" 0, 1); HDMI VGA BT. 1120 output outputs on screen at the same time,
After setting on BT. 1120 no picture, two reasons: 1. The port multiplexing is not configured for BT. 1120 output, 2. Sii9022 no drive
Reference to the SDK (Hi3536_SDK_V2 0.6.0 \ package \ mpp_single \ mpp_single \ ko) pinmux, the inside of the sh port multiplexing

Written (the arch/arm/lib/board. C files) of void LogintImage (void) function tail recompiling uboot first complete,
I tried the code directly into vou. C files inside, can't normal output, specific don't know why,
The second step: sii9024 driver problem, I tried all kinds of methods to use Hi3536 I2C to initialize sii9024 but didn't succeed, finally the darling of the plugins an 8-bit MCU alone again at the start of the initialization parameters, a set of initialization code below I tested are available,

I am a beginner, haisi chips have a wrong place please correct me!
