Part Number: SN65DSI86
I am trying to enable the color bar using the display port of the SN65DSI86. (I am using an ASUS monitor through a display port to HDMI converter). However semi auto link training is failing with 0xF8=0x02 and the monitor remains black. I have tried writing the registers exactly as given in the example (Typical Application 1080p panel) in the SN65DSI86 bridge documentation (additionally writing to the color bar and other related registers). If anyone has any sample code that does this or has any insight on this please share!
The addresses and data that i am writing are given below in order,
address = { 0x0a, 0x10, 0x12, 0x5a, 0x93, 0x94, 0x0d, 0x95, 0x64, 0x74, 0x75, 0x76, 0x77, 0x78, 0x96, 0x20, 0x21, 0x24, 0x25, 0x2c, 0x2d, 0x30, 0x31, 0x34, 0x36, 0x38, 0x3a, 0x5b, 0x3c, 0x5a, 0x96}
data = { 0x06, 0x26, 0x59, 0x05, 0x20, 0x80, 0x01, 0x00, 0x01, 0x00, 0x01, 0x0a, 0x01, 0x81, 0x0a, 0x80, 0x07, 0x38, 0x04, 0x2c, 0x00, 0x05, 0x80, 0x94, 0x24, 0x58, 0x04, 0x00, 0x10, 0x0d, 0x01}
(I am waiting for the PLL to lock)
