Fix black screen #72

Open mkryuchkov opened 1 month ago

mkryuchkov commented 1 month ago

Newer versions of platform kit cause black screen on start. KNOMI v2 has this issue, not sure bout v1.

Alternative option is to adopt source code to newer kits, but I don't have any debug abilities like hw dev-kit or esp32 debug knowledge.

This PR is just about to make current version working.

came across this as my knomi2 screen went black. how do i get into the device to change that line. Light on back of device but i dont know how to get into it.

@bodydropped72 I described the way here https://github.com/DiverOfDark/KNOMI/issues/239#issuecomment-2114596078

So you can revert your KNOMI to precompiled version (It also possible to use DiverOfDark's re-flasher and choose revert to stock option) and then flash your build, or just flash yours with fix on top. KNOMI2 has esp32s3 onboard so if device has red light, connected via usb and identified by pc it should be flashed. I described nuances in the comment by link.

i have looked at the link you sent me. the knomi2 when plugged into my computer via usb is not recognized by it (looking in device manager).

@bodydropped72 Check if new COM port appeared after plug in (it's okay if it does; this port is need for flashing); If not you may install driver from https://www.wch-ic.com/downloads/CH341SER_EXE.html and check again.

Generally, you should be able to flash knomi the same way you flashed black-screen FW. Try to flash precompiled FW first with sectors set as I described (0x0000 for bootloader).
