AM3517: LCD SDI mode configuration

Hello,

 I try to configure the SDI mode of the LCDC according to the ref. manual. 

I tried two ways of configuration:

1) SDI Clock Source/Frequency Change Sequence (ref. manual p1404)

Here, I end up up with step 4 (waiting for DISPC_CONTROL->GoLcd bit to become 0, which it won't)


2) SDI pll configuration (ref. manual p1399)

Here, I end up waiting for the PLL lock bit in DSS_SDI_STATUS, which won't go to 1.

Has anyone experience with the SDI mode and can provide help?

Thanks in advance.

Best regards, Timm Feinle.
