Hi,
I'm unsuccessful at getting a brand new Display Module 13.2 to work with a Core v.2.6 or a Fire v2.6.
I'm using an HDMI display that works fine with the "Atom PSRAM - LCD Display Driver Kit" using UIFlow platform. But my Display Module 13.2 doesn't display anything on that monitor using UIFlow, Arduino or the Easyloader demo program with my Core or Fire controllers.
Looks like there's a problem with the FPGA. The debug output of the demo program is the following with my Basic Core V2.6 (it's basically the same output with a Fire V2.6 as the program doesn't recognize the PSRAM of the Fire):

I guess the Display Module 13.2 I received was defective from the get-go. The FPGA seems not responding after the SRAM is written. But any help would be greatly appreciated in troubleshooting my issue if I'm missing something somehow.
Thanks a lot in advance!
