Support for new Neptune 3 Pro with SM32F402

General Discussion
1

Hello,
I would like to ask about compatibility with these new printers. There seems to be no option to select STM32F402 in makeconfig and the build for SM32F401 does not seem to work. The flash stops at uploading firmware

This is how new board looks like

Is there any config that currently exists and can work?

What version is your motherboard

I believe you are correct on selecting 401 but I think you have to add 32kib bootloader

Would that work with ZNP-K1-V2.0 (STM32F402) for Neptune 4 Max?

# This file contains common pin mappings for ZNP-K1-V2.0 
# boards. To use this config, the firmware should be compiled for the
# STM32F402. When running "make menuconfig", enable "extra low-level
# configuration setup", select the 32KiB bootloader, and serial (on
# USART1 PA10/PA9) communication.

# The "make flash" command does not work on the ZNP-K1-V2.0. Instead,
# after running "make", copy the generated "out/klipper.bin" file to a
# file named "elegoo_k1.bin" on an SD card and then restart the ZNP-K1-V2.0
# with that SD card.

# See docs/Config_Reference.md for a description of parameters.
