Hi :
I want to display simultaneously dual LCD1 and LCD2 with the same source , LCD1 signal is from DR745 Vout1 pin ,LCD2 signal is from Vout3 Pin via FPD3 cable, set CONFIG_DRM_OMAP_NUM_CRTCS=2 , only one LCD can work if I enable display0 or display1 at DTS file , but two display are enable, log show error information : 44000000.ocp:L3 Standard Error: MASTER MPU TARGET DSS (Read): At Address: 0x00001630 : Data Access in User mode during Functional acces. both do not work.
How can I resolve this issue? and expect your answer ,thank you!
