[Raspberry Pi Original Development] freakalad:
Not really - mixed bag.

Vanilla flash seems to (initially) work on my lounge HDTV, but as it's far removed from my lab workbench, so I have no UART & cannot debug/logcat.

On my lab monitor(s), I'm getting issues. The one I'm favouring now it on I run another RPi on (OSMC, etc) capable of 1920x1080 (CEA hdmi_group=1, 1080p@60Hz hdmi_mode=16), but based on your comments, this point is moot.

roger

Just completed another (re)flash, so will implement your comments/suggestions & amend/supplement this thread with additional findings.

Thanks for the hard work & fantastic outcome

From a fresh flash, I've only tweaked system/build.prop, debug.drm.mode.force=1920x1080 - which fires up my display nice now. (about to re-confirm EDID info from fresh raspbian)

I start the initial setup, but hangs/crashes past the point where the network is config'd.

Error dump I get: https://pastebin.com/y2ddZ1bt

(something to do with CMA/memory allocation?)

Minicom dump, including full logcat & dmesg: https://termbin.com/7wa5

(I would LOVE to see this project taken up in mainline Lineage, with managed means of bug reporting, but I can certainly respect the decision not to for reasons stated)
