Puya PY32 MCU SDK

This repo contains a GCC/Makefile-based build system for Puya PY32 MCUs, including the PY32F002A, PY32F003, and PY32F030.

Also included are vscode build/launch configs using Cortex-Debug and pyOCD.

pyOCD support

Puya's DFP is not currently indexed anywhere, so pyOCD can't automatically download it with the typical pack update and pack install commands. However, we can manually download and extract this pack, and then install the pack using cmsis-pack-manager (which PyOCD uses under the hood)

First, get a copy of the DFP, which is found in Puya's PY32 SDK download available on their PY32 web page. The download link is listed under the "Datasheet" column in the far right of the device table — you can directly download the file here, though this link may be out of date. If you extract this RAR, you'll end up with documentation, code samples, and the Puya.PY32F0xx_DFP.1.1.0.pack DFP pack.

Next, unzip Puya.PY32F0xx_DFP.1.1.0.pack (it's just a ZIP with a .pack extension). Then, copy the pdesc file to cmsis-pack-manager's repository along with all the other pdsc files (this will be located in your Python distribution). It needs to be renamed to Puya.PY32F0xx_DFP.1.1.0.pdsc (with the version numbers present).

Next, copy the original DFP pack file to Puya\PY32F0xx_DFP\1.1.0.pack creating directories and renaming the pack file accordingly.

Now, add the pack to cmsis-pack-manager:

PS C:\> pack-manager add-packs Puya.PY32F0xx_DFP.1.1.0.pdsc

Now you can install the actual target support in PyOCD:

PS C:\> pyocd pack find PY32
  Part          Vendor   Pack                Version   Installed

  PY32F072xB    Puya     Puya.PY32F0xx_DFP   1.1.0     True

PS C:\> pyocd pack install PY32F003x8

J-Link Support

Using the J-Link Device Support Kit Segger Wiki page as a reference, create a JLinkDevices\Puya\PY32 directory structure in your home directory's Segger application data folder (on Windows, it's in C:\Users\<USER>\AppData\Roaming\SEGGER\). Pull in all the FLM files from the aforementioned DFP to this directory, and add a Devices.XML file that points J-Link to these files. Here's an example for the PY32F002Ax5:

<Database>
  <Device>
    <ChipInfo Vendor="Puya" Name="PY32F002Ax5" WorkRAMAddr="0x20000000" WorkRAMSize="3072" Core="JLINK_CORE_CORTEX_M0" />
    <FlashBankInfo Name="Internal code flash" BaseAddr="0x08000000" AlwaysPresent="1" >
      <LoaderInfo Name="Default" MaxSize="0x5000" Loader="PY32F0xx_20.FLM" LoaderType="FLASH_ALGO_TYPE_OPEN" />
    </FlashBankInfo>
  </Device>
</Database>

py32-template's Issues

pack manager did not works

Hi,

What version of python, pyocd and cmsis-pack-manager are you using? I'm trying to do your steps, but cmd or Power Shell can't find pack-manager.

Regards.
