Hi, I am new to PIO. i have several Py32f002A chips decided to learn embedded and learn to program random microcontroller as long as they have firmware files. i am totally Newbie so pls be kind to me. i already know some basic stuff had watched a you tube tutorial on setting up Py32 on Keil microvision but the free version has processing limit to 32kb. i was searching for aleternate platforms to program and upload to my Py32. tried STM32 , compiled the files but failed on Uploading didint understand anything .All i need to know is what are the steps and cruicial files needed to compile and upload the PY32 MC.
Creating a new PlatformIO platform is a very involved task. It needs a lot of background knowledge on how PlatformIO works internally (platforms, packages, frameworks, board definitions, builder scripts) as well as how microcontroller firmwares are created in general (compiler options, linker scripts, startup assembly files, upload programs like OpenOCD, debugger probes, …).
A good point to start reading would be

- https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html etc.
Also know that someone already created a PlatformIO platform for PY32F0 chips:
Adding a new board definition, updating or adding new framework packages and modifying the builder scripts to work for those chips will be easier than creating a new platform from scratch. But for that, you would have to at least read through all previous links to get started.

Thanks for the reply, I have the Firmware files containing HAL drivers, CMSIS core startup and system files. And some examples containing linker id, OpenOCD config of said microcontroller and Stlink config of OpenOCD.
Anyway, I think Keils Free 32kb version more than enough bcus the Py32f002a has only 20k flash and 3kb sram. I will learn slowly to program microcontroller without any dependency only using Firmware and free tools.
