Hi everyone,
i struggle to make the display port work on a10 sockit. To be more precise, i use the demo given in rocketboards, so in TX mode at 5.4Gbps, 1920x1080p test pattern gen II and Clocked Video output with colour bars to be displayed. After AUX channel transactions, i can read that TX channel has been correctly trained (i refer to the screen resolution that has been detected) --- Quote Start --- ------------------------------------------ ------ TX Main stream attributes ----- ------------------------------------------ --- Stream 0 --- MSA lock : 1 VB-ID : 10 MISC0 : 20 MISC1 : 00 Mvid : 232F Nvid : 8000 Htotal : 2200 Vtotal : 1125 HSP : 0000 HSW : 0044 Hstart : 0192 Vstart : 0041 VSP : 0000 VSW : 0005 Hwidth : 1920 Vheight : 1080 CRC R : 22f0 CRC G : 0a2e CRC B : b7bb --- Stream 1 --- MSA lock : 0 VB-ID : 00 MISC0 : 00 MISC1 : 00 Mvid : 0000 Nvid : 0000 Htotal : 0000 Vtotal : 0000 HSP : 0000 HSW : 0000 Hstart : 0000 Vstart : 0000 VSP : 0000 VSW : 0000 Hwidth : 0000 Vheight : 0000 CRC R : 0000 CRC G : 0000 CRC B : 0000 ------------------------------------------ -------- TX Link configuration ------- ------------------------------------------ Lane count : 1 Link rate : 1620 Mbps --- Quote End --- But nothing happens on screen. And i don't understand why i get only one lane count. 1.6Gbps is not enough to handle 1080p If you have an idea, please share it. ThanksLink Copied
