Describe your issue:

/dev/serial/by-id/usb-STMicroelectronics_MARLIN_STM32G0B1RE_CDC_in_FS_Mode_203D32775841-if00

it looks like it can’t flash, microsd card issue?

it seems issue in SKR docs, not v3.0 nor v3.0.1 having right processor i have STM32G0B0 meanwhile in docs STM32G0B1 and STM32F401

Welcome chiboreache, I agree, you have indeed a STM32G0B0 on your SKR, but in your build config (line 3 of your posted code) you chose

Good luck, hcet14

i have tried a lot of configs, B0, B1, after that i started using precompiled ones, result is always the same :pensive:

Did you try to install Klipper using KIAUH?

You may read Sineos Installing Klipper with KIAUH

I guess lwq690 solved that with No firmware for STM32G0B0RET6 ? · Issue #775 · bigtreetech/BIGTREETECH-SKR-mini-E3 · GitHub

by buying new board with right processor !? :hot_face:

i installed it via MainsailOS, which is included KIAUH, doing all that stuff, yeah

A couple of things I found are important when Flashing new Firmware onto a main controller board:

  1. Ideally use an SD Card that is no more than 2GB in size. This is the most basic type of SD Card and is most likely to be read without problems on the SKR Mini. If you don’t have an SD Card that size then partition it with the main partition 2GB (although people often recommend 8GB).
  2. Make sure the SD Card is formatted with FAT32.

If these don’t work, then you’ll need to explain your process in exact detail so we either identify a problem or follow the steps and see if we can replicate the problem.

Why would you buy a new board? I never suggested that!

Did you try lwq690’s settings?

you absolutely right (but i figured it out by myself :yum: )

i used 32Gb card for SKR and 8Gb for OrangePi, now i swapped them and reflashed accordingly and everything is working like a charm :ok_hand::relieved:

i think this essential knowledge should be added to docs with red frame around, since small sized flash mems are rare nowadays…

and what about processor? this also should be reflected in official documentation

and one more thing which config is better SKR-mini-E3-V3.0-klipper.cfg or generic-bigtreetech-skr-mini-e3-v3.0.cfg ? for Ender3 (basic)

It is documented Releases - Klipper documentation

Support for stm32f7, stm32g0b0, stm32g07x, stm32g4, stm32h723, n32g45x, samc21, and samd21j18 chip variants.

oh, my bad, i’ve got confused :smiling_face:

it was BTT docs

thanks!
