Hi Madam/Sir,
Fig.1 is our current display diagram. it consists of Intel SoC, DS90UB929, DS90UB928 and LCD panel.
we met LCD panel sequence problem since there is no VDD_EN and BKLT_EN from HDMI and we cannot pass it to LCD panel thru GPIO of DS90UB929/928.
Fig.1
we wounded if there is any way to extract "VDD_EN" and "BKLT_EN" from HDMI and pass it to LCD panel thru GPIO of DS90UB929/928? like to Fig.2 or others.
please kindly share us your thought or comment. Thanks a lot.
