Trying to port Repetier-Firmware to Creality3D Silent Board V.4.2.7 but stuck....

Hi guys,

I've tried to get rid of Marlin 2.0.7 on my Ender 5 with the silent board V.4.2.7 which features a STM32F103RET6. But I'm to dump to get to the next level...

What did I do 'till now?

I searched for all pins used by Marlin and put 'em in a new file creality_v4_2_7.h under ...\Repetier-Firmware-dev2\src\Repetier\src\boards\STM32F1\boards

I tried to add a new environment env:STM32F103RET6_creallity (same as in Marlin PlatformIO-project)

I tried to get all linking and compiling arguments and parameters out of Marlin scripts.

But the only effect is that I crashed my repetier-PlatformIO-project. There seems to be a gap of information (HAL?) I'm unable to close.

This is what I borrowed from my active Marlin firmware and ported to Repetier in creality_v4_2_7.h (copy of the skr_mini-files):

Any hints or someone who knows what to do? Or is there anyone who can use this as a starting point for integration in repetier-dev2?

So your problem is that you already can not compile?

The platformio settings from marlin are likely to not work. They contain much "special" clutter for marlin files etc. Better use skr_mini_e3_v1_2 as starting point, which has our clutter and is also for STM32F1 based boards. Most important is to have

board = skr_mini_e3_v1_2
adjusted and that the board description exists. Actually that board already uses stm32f103rct6 cpu so using that identifyer should most likely already work if you combine it with your board.

In constants add your board with id 2503 to be in STM32F1 id range and add a include in src/boards/STM32F1/pins.h
so that it gets found when you select it as motherboard.

Then compilation should work if your config uses no unknown identifiers.

Hi,

thanks for the hint! I'll give it a try and will report! ;-)

Hi guys,

after several tries I can not compile the firmware. Even a fresh download of dev2 and trying to compile for a SKR mini does not work. Many .h-files seem to be missing which are used as includes. Think I'll stop here, let Marlin do the magic and wait 'till another mainboard or printer! Or until it rains again... ;-)

I wish you a good progress in developement!

Ingo
