Hello. So recently got a ender 3 v2 printer and got octoprint and all that installed on a pi. No issues there. But when trying to install marlin on printer it will not flash. The board is 4.2.2. The screen updates just fine but not the board. It always boots up normally but not like installing firmware according to the videos I watch. For example it boots normally instead of black screen for 10 or so seconds. Any advice?
#ender 3 v2 can't flash firmware.

rename your firmware.bin file to 12345.bin & see if that doesn't work (Creality motherboards want the new firmware file to have one of the first few characters be different than last one, or it refuses to update)

Still the same instant boot. Even with the 12345.bin only on the SD card
Even tried 2 different firmware files.

ok, mine flashed in maybe 4 seconds at most before my creality board crapped out ... are you sure it didn't flash correctly?
(my Creality board blew a bed thermistor-sense resistor... had nothing to do with the firmware or flashing...just bad QC & a crap resistor made it start always reading the bed as >300°C 😂)

firmware version is still saying 1.0.7 and apolgies needed to head to bed

np, I needed sleep too.
...can you take a picture of your board, showing the silkscreened label info, and another of the MCU (biggest chip near the middle of the board) that we can read the text on the chip in, please?
Also @queen cosmos quick question, where EXACTLY are you putting the SD Card when you're trying to flash new firmware (it can't flash motherboard firmware from a card inserted in the screen's reader, even though it can easily be set up to read gcode files from there)

Its not in the screen lol. that updates just fine. but give me a moment to expose the motherboard

ok, just checking on the screen part, since it HAS been the problem before...

ok, so it's verified as a creality 4.2.2 board with GD32F303 ret6 for the chip
...so might have to try building with the "maple" environment, at least until the new PR for native GD-chip support comes in.
queen cosmos
so what do i need to do?
thats one of the firmware sites I used. including the GD version

I thought you were compiling real Marlin (from https://github.com/MarlinFirmware/Marlin & https://github.com/MarlinFirmware/Configurations ... please download version "bugfix-2.1.x" of both.)
Unfortunately, we cannot support random derived firmware branches from wherever you find them 😕
queen cosmos
I will try all that.

Over the next day or 2 I will attempt to do the custom build to fit the ender 3 v2 If you are available to read over what I have done to make sure everything is correct that would be much appreciated I started off one of the links you gave me as a building block. @unique stream
