Installing pyupdi

paulskirk53 · February 10, 2021, 1:27pm

Hello, I have included pyupdi options in my pio.ini file and in this url it explains how to install pyupdi:

MCUdude/MegaCoreX/blob/master/PlatformIO.md

# PlatformIO

[PlatformIO](https://platformio.org) is an open source ecosystem for embedded development.
It has a built-in library manager and is Arduino compatible. It supports most operating systems; Windows, MacOS, Linux 32 and 64-bit, ARM and X86. And best of all, MegaCoreX is supported!

* [What is PlatformIO?](http://docs.platformio.org/en/latest/what-is-platformio.html)
* [PlatformIO IDE](https://platformio.org/platformio-ide)
* Getting started with [PlatformIO IDE](https://docs.platformio.org/en/latest/integration/ide/visualstudio.html) or [PlatformIO command line interface](https://docs.platformio.org/en/latest/core/index.html)
* [Advanced functionality](https://docs.platformio.org/en/latest/platforms/atmelmegaavr.html)
* [Project Examples](https://docs.platformio.org/en/latest/platforms/atmelmegaavr.html#examples)


## MegaCoreX + PlatformIO
MegaCoreX and PlatformIO goes great together. You can do serial uploads and upload using a dedicated UPDI programmer, but you can also let PlatformIO calulate the fuses and load the correct bootloader file, just like Arduino IDE does!

PlatformIO uses the information provided in platformio.ini to calculate what fuse bits and what bootloader file to load.
Simply provide enough information and run the following commands:

```ini
; Only set fuses

This file has been truncated. show original

where it indicates to use the following command in PIO:

pip install https://github.com/mraardvark/pyupdi/archive/master.zip

however pip is not recognised by PIO:

pip install https://github.com/mraardvark/pyupdi/archive/master.zip
pip : The term ‘pip’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1

pip install https://github.com/mraardvark/pyupdi/archive/master.zip

  + CategoryInfo          : ObjectNotFound: (pip:String) [], CommandNotFoundException
  + FullyQualifiedErrorId : CommandNotFoundException

Is there an alternative install method?

thanks very much for help

I’m assuming you want to install PyUPDI within the isolated Python environment that PlatformIO uses.

For that, open a PlatformIO CLI and then execute the pip install https://github.com/mraardvark/pyupdi/archive/master.zip command.

If that still doesn’t work, talk to the Python interpreter executable directly. Execute pio system info and copy the value of Python Executable then copy-paste that and do

<python executable path> -m pip install https://github.com/mraardvark/pyupdi/archive/master.zip

thanks, I found the PIO CLI and installed pyupdi.

I got a message to inform me there’s a newer version of pip, so updated using the command:
pip install --upgrade pip

but it didn’t go well as described below. Have I messed it up and if so how would I correct things?

just to note I have admin rights on the machine. (WIN 10)
thanks
Paul

MIght be intentional because its in own pyenv…? I’d rather let PlatformIO’s pip version be in peace.

But also note that you are talking to your system PIP here, and not PlatformIO’s pip when you executed pip install --upgrade pip. The full command above

should have been used.

probably completely indicative that I haven’t a clue what I’m doing. Never do something unless you know what you’re doing…

I just need this pyupdi thing because apparently it’s required to program an avr4809

thanks for help
