Hi @Mc2023 ,
As I know, our EVK with dual core are all the MIPI interface, not the parallel interface.
But, our RT11XX with dual core can support the parallel interface, just not fan out it to the elcd RGB interface, the parallel interface is the same as the MIMXRT1060-EVK, MIMXRT1050-EVKB board.
So, if you have the RT1060, RT1050 board, you also can use that board test it, then to the dual board, you can design your own board.
Wish it helps you!
Best Regards,
Kerry
