[solved] Building Marlin for STM32: Unsupported Platform!

Hi,

I try to build git branch Marlin-bugfix-2.1.x for the STM32F103RE_creality
The Ender mainboard. Version 4.2.7.
Configurations-bugfix-2.1.x/config/examples/Creality/Ender-5/CrealityV427

But it does not want to build. With platformIO I get these error messages:

$ pio check
Checking STM32F103RE_creality > cppcheck (board: genericSTM32F103RE; platform: ststm32@~12.1)
Marlin/src/HAL/platforms.h:58: [high:error] #error Unsupported Platform! [preprocessorErrorDirective]

But there are STM32 in the list, so why doesn't it work?

With ArduinoIDE it crashes with strange library errors. Wrong version?
I tried u8glib-HAL 0.5.4, 0.5.3 and 0.5.2

Marlin-bugfix-2.1.x/Marlin/src/HAL/AVR/u8g_com_HAL_AVR_sw_spi.cpp: In function 'void u8g_com_arduino_init_shift_out(uint8_t, uint8_t)':

   u8g_outData = portOutputRegister(digitalPinToPort(dataPin));
               ^

   u8g_outClock = portOutputRegister(digitalPinToPort(clockPin));
                ^
exit status 1
Compilation error: cannot convert 'volatile uint32* {aka volatile long unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment

btw, how can I read the stock firmware from the board using avrdude?

thanks

PS: The forum documented it's 10 years since I fiddled with the MendelMax 2. Now I am back

a) pio check "Perform static analysis check on PlatformIO based project. By default Cppcheck analysis tool is used."

this has nothing to do with building the firmware normally.

Most of these static analysis tools are not up to the task of doing anything useful in marlin

use pio run, or even better use vscode as a gui.

b) no one uses Arduino IDE any more, its slow and painful and you have to install correct versions of libraries and build environments manually

c) you cant use arvdude on a stm32

Thank you very much for your answers.
I installed vscode + pio IDE.
But I still get the "Unsupported Platform!" error.
It comes from this file [github.com]
The STM32F1 is included. why doesn't it match?

Solved.
I successfully built from the bugfix.zip, not the git branch.
