Add Support for GigaDevice GD32F and GD32E chips #3927

Open maxgerhardt opened 3 years ago

maxgerhardt commented 3 years ago

What kind of issue is this?

See https://www.gigadevice.com/products/microcontrollers/gd32/ and catalog for GD32 ARM-type chips. GD32V (RISC-V based) chips are already supported, but not the GD32F (Cortex-M3 and Cortex-M4) and GD32E (Cortex-M23, Cortex-M33 and entry-level Cortex-M4).

The chip vendor supplies its own STM32-like Simple Peripheral Library (SPL) framework as development tool, see http://www.gd32mcu.com/en/download/7?kw=

I currently support the GD32F130C6 and -C8 versions at https://github.com/maxgerhardt/pio-gd32f130c6 with the vendor's SPL pacakge, as maxgerhardt/framework-spl@2.10301.0 (aka combination of GD32F1x0_Firmware_Library_v3.1.0 and GD32F10x_Firmware_Library_V2.1.2 from vendor), and the GD32F103RC chip (with the same SPL version) under https://github.com/maxgerhardt/pio-gd32f103, but official support would be good.

I don't fully understand the chips but it might be that the GD32F103xx chips are exact clones of the STM32F103x chips, which also means they would implicitly be supported by the Arduino-STM32 core. For other chips like the GD32F130x series, I did not find a correlation.

FYI: I've made an update to the framework-spl package to also incorporate the GD32F350xx series.

The framework-spl package is at https://github.com/maxgerhardt/pio-framework-spl-with-gd32 with a new example (board definition + firmware code at) being at https://github.com/maxgerhardt/pio-gd32f350cb.

I would very much appreciate this - I'm looking into using platformio to program a GD32E103xx

maxgerhardt commented 3 years ago

Update for those who are interested: I have recently gotten in contact with motivated people who also have connections to GigaDevice. They gave us a previously unreleased Arduino core for some GD32F3x chips. We are developing this further into a fully-fledged Arduino core with support for more boards at https://github.com/CommunityGD32Cores/GD32Core-New. Contributers welcome.

For GD32 (ARM-type) chips I've also created https://github.com/maxgerhardt/platform-gd32 in which I plan a major overhaul and unification of all these smaller (SPL) projects linked above.

Also note that mbed-os has support for some GigaDevices boards now. See https://github.com/ARMmbed/mbed-os/tree/mbed-os-5.15.7/targets/TARGET_GigaDevice for mbed-os 5.x and https://github.com/ARMmbed/mbed-os/tree/master/targets/TARGET_GigaDevice for mbed-os 6.x. I plan to add mbed-os build support for these boards, too.

@crosswick Just for my interest, what exact chip or board do you have in mind?

crosswick commented 3 years ago

I'm working with the GD32E103C8T6 and GD32E103CBT6; boards are my own design and this one for prototyping: https://www.aliexpress.com/item/1005002023908240.html

By the way - I have gotten a working toolchain together by using Keil 5 in a Windows VM, but would like to be able to work in platformio on macOS.

Yesterday I've added a board definition for the E103C8 here and expanded the SPL blinky and UART example to work with it. If you clone this, import the gd32-spl-blinky project folder in VSCode and change these lines to 

platform_packages = 
    framework-spl-gd32@https://github.com/maxgerhardt/pio-spl-gd32-new.git

can you do a successful build & upload for the genericGD32E103C8 environment? The default upload protocol is stlink btw, but also jlink is supported. Since I don't have the board (yet) it would mean a lot to me if someone tested my platform :D

crosswick commented 3 years ago

@maxgerhardt alright I've gotten it to build and upload, albeit with some RAM size-related warning, but no blinky. Perhaps I can show you the terminal output somewhere?

maxgerhardt commented 3 years ago

Hm okay, can you open a new issue in https://github.com/maxgerhardt/platform-gd32/issues with the output and the used platformio.ini? Just to keep the discussion separate from here :)

maxgerhardt commented 3 years ago

Update:

Me and a group of people (@obra, @howitzer74, ..) have recently started a massive initiative to support GD32 chips in PlatformIO.

With

And we are also looking for contributors and testers, Discord link is in the repo.

See the repos at

My smaller per-chip repos are considered outdated with the new repos above.

Hello, I also have at least four gd32 development boards. I originally planned to build its own platform support package, but now it seems unnecessary. I will use and develop my own projects, such as grbl controller running on CNC or laser (my own ported version). I believe this is a very good experience.
