pyocd install custom cmsis pack

[WGR7]

Hi,

I'm need to install a custom pack for Puya PY32 MCUs. I've saw some tricks unzipping the DFP and copying some pdsc files to a specific folder, but I'm getting a failure when trying to add the pack to cmsis-pack-manager running "pack-manager add-pack abcd.dfp" command. The pack-manager was not found on command line.

So, Is there a method to install a custom pack DFP calling pyocd on command line?

@WGR7 You can invoke pyocd with the --pack argument, as in:

pyocd flash --pack "Keil.LPC1100_DFP.1.4.0.pack" -t "LPC11C24FBD48/301" blinky.hex

Unfortunately pyocd and cmsis-pack-manager do not support easy way to install individual .pack s.

But there is a way to accomplish that part manually. Let's see how it can be done step-by-step.

1. check the location of cmsis-pack-manager's pack repository. pack-manager print-cache-dir normally above should work fine. but if it doesn't try this one below. python -c "import cmsis_pack_manager.pack_manager as pack_manager; pack_manager.main()" print-cache-dir 　 I'm using windows, so it will show a path like this. C:\Users\ username \AppData\Local\cmsis-pack-manager\cmsis-pack-manager

2. clear the cmsys-pack-manager's pack repository to avoid any complication. python -m pyocd pack clean

3. create an empty directory at the location where pack repository will be placed. mkdir $env:LOCALAPPDATA\cmsis-pack-manager\cmsis-pack-manager

4. Find and download specific .pack you want to use. search by device name: https://www.keil.arm.com/devices/ or search by pack name: https://www.keil.arm.com/packs/ 　 say I wanted to use Nuvoton NuMicro_DFP 1.3.20, it can be downloaded from this page. https://www.keil.arm.com/packs/numicro_dfp-nuvoton/versions/

5. extract .pdsc out of .pack .pack file is actually a .zip file. You can modify the file extension if you want , and then extract its content. find a file with .pdsc extension. for example it may look like Nuvoton.NuMicro_DFP.pdsc .

6. create/update pack index by installing the .pdsc file pack-manager add-packs path_to_where_you_put\Nuvoton.NuMicro_DFP.pdsc try following if above fails. python -c "import cmsis_pack_manager.pack_manager as pack_manager; pack_manager.main()" add-packs path_to_where_you_put\Nuvoton.NuMicro_DFP.pdsc

7. manually place the .pack file to where it is expected to be. mkdir $env:LOCALAPPDATA\cmsis-pack-manager\cmsis-pack-manager\Nuvoton\NuMicro_DFP copy path_to_where_you_put\Nuvoton.NuMicro_DFP.1.3.20.pack $env:LOCALAPPDATA\cmsis-pack-manager\cmsis-pack-manager\Nuvoton\NuMicro_DFP\1.3.20.pack

8. check that pyocd is properly recognizing the pack you installed. python -m pyocd pack show should show

      Pack                  Version
    ---------------------------------
      Nuvoton.NuMicro_DFP   1.3.20

9. check that pyocd properly lists devices from the pack you installed. python -m pyocd list --targets

You may repeat step 4. ～ for as many .pack s you want to have.

Hope this info helps.
