Sure. Give me a bit though to tidy it up. At the moment im running 3 seperate projects for simplicities sake. 32 bit, 24 bit and 16 bit, as all the primitive drawing routines take in different colour values.Could you share the codebase for this test?
I have 7” 800*480px display with the same driver and will be hooking it up to my Devboard V5 when the adapter PCBs arrive, and have been considering use of the PXP to write rectangle clips to the main eLCDIF buffer for LVGL partial mode implementation (to improve render/write times and as much non blocking transactions)
I recently made a super nice PCB with lots of outputs and sensors. It runs stable on 221MHz, but I use the same SDRAM layout for all boards. I keep it simple by copying the "bare minimum" straight over to any new project that is similar. So I use that 10pF cap that me and Defragster decided on when we tested back in the day.
I guess different designs makes for different results, it just proves that layout is super hard!
Exactly! It took me the third itteration to get this board right. The first 2 efforts i kept getting 9 blinking lights (Unknown error) . I thought it was my power delivery or my soldering. Yet the Bootloader was marrying and locking itself to the IMXRT1060 chip.
Turns out after a good close look at the schematic i was missing the 2 DCDC ground connections. So my voltage's where all showing as good, however the internal DCDC converter was not grounded properly.
Have you got a photo of your latest pcb?
