IMX8QXP ELCDIF DVI mode with external sync signals

mikhaillevitin — Wed, 22 Jan 2020 21:54:13 GMT

Hi

We have imx8qxp Soc with the off-chip hdmi converter (sii9022a). I'm trying to get picture using ELCDIF DVI mode ( i think problem is in embedded sync signal settins which is not yet clear for me.

The question is: is it possible to get external hsync/vsync along with BT.656 DVI/YCbCr 4:2:2 color space mode (LCDIF_VDCTRL4[18] = 1 and LCDIFCTRLn[20] = 1)?

Thanks in advance.

Hello,

Unfortunately, the i.MX8QX is still under development. Most of the software may be subject to change. We cannot provide proper support of this SOC until is officially released. What I suggest you go with your DFAE. He could help you better with this problem.

Best regards,

Diego.
