ESP32-P4

Hi @Builty
I see that you started experimenting with P4 platform on JC4880P443C.
I was thinking about ordering the Waveshare ESP32-P4-WIFI6-Touch-LCD-4.3
or Waveshare ESP32-P4-WIFI6-Touch-LCD-5 to do some experiments myself.
From what I see there should be no hardware mods needed for host mode.
Do you see any limitations or issues that those boards could have?

Hi. Both boards look OK to me. The 4.3" is very similar to the JC4880P443C I'm working with, same LCD and touch screen.
OTG looks OK as far as I can see.

So far the code is coming along OK. I have some issues with Bluetooth (the P4 uses the external C6 in hosted mode) and some issues getting the LCD to display proper data.

I have the JC4880P443C pretty much working now. LCD/touch/USB/WiFi all good. OTG worked fine with no mods needed (must be the high-speed port.)
I just need to update the C5 co-processor firmware to get bluetooth going.
