Article: NuttX RTOS for PinePhone: Feature Phone UI in LVGL, Zig and WebAssembly

[WhiteHexagon]

(Well, technically, some hardware also allows you to remap its DMA to a different address, provided by you, usually under some constraints such as a minimum alignment, but I do not know whether this is possible on the PinePhone.)

Thanks Kevin, yes, this is what I try to do, DMA accessed, direct memory without a driver, and no blit. I hope this will allow me eventually some hardware GPU acceleration, if I ever find documentation for the openVG, or if not just access to the 3 planes and mixers for some UI effects.  Lets see   Currently my USB micro SD card adapter broke, so testing is on hold for a few days, and it has prompted me that I really should have an extension cable for the PP card slot to avoid too much ware n tear during development, but struggling to find one locally.

After that I might have another go with the audio routing, now that I have so much of the SoC working in Zig I feel a bit more confident to try again.  Unless the PineTab-V comes back in stock before then!

btw I did see mention of some kind of recovery mode, 'FEL Mode' that sounds useful for development, but no way to switch the PP into this mode?
