Dir sir,
We are working on chipset 3715 omap processor with MIPI DSI interface. We have configured the Linux 2.6.37 (Android_4.0.3-DevKit) kernel to include the DSI driver and panel timing information. We have followed the instructions in AM/DM 37x TRM 7.5.4.8 to program the registry to video mode but the screen is still black with an error below:
omapdss DSI error: DSI error, irqstatus 40020
We checked the TRM document and found:
The RESYNCHRONIZATION_IRQ indicates software users that the video port works but the configuration of the timings for the display controller (DISPC) and for DSI Protocol engine may need to be modified to avoid the resynchronization to occur.
The timings we used(hbp/hfp/vbp/vfp/hsw/vsw) works in u-boot stage but we have no idea how to modify them to solve this issue. Thanks much for any suggestions.
Jesse
