Board support request: LoRa E5 Dev Board / STM32WLE5JC

[nobodywasishere]

This is the board/mcu I am looking to add support for, which is very similar to #543.

I have created this board json called lora_wle5jc.json that may work, I don't have a board on-hand just yet to test it yet and putting it in ~/.platformio/boards didn't let it show up in PlatformIO. I don't know of any frameworks that currently support it, but that is okay for what I am hoping to use it for (just bare-metal) (if a framework is required, please let me know). As well, I am not sure what upload protocols it supports just yet.

I have a work-in-progress version going here that I'll update as I test it

[nobodywasishere]

Also this board is supported by Zephyr and there's useful documentation on how to use it here

I believe i've gotten both the CMSIS and STM32Cube frameworks working, still waiting to get a board to test them but they compile without errors. I'm starting to work on examples for these here. framework-stm32cubewl is already published to the PIO registry, and I'm currently waiting for framework-cmsis-stm32wl to be approved.

[nobodywasishere]

I've got working blinky programs with both CMSIS and STM32Cube frameworks, and have verified that those work for flashing the board. Should I create a PR with my board file? Currently still waiting for the framework-cmsis-stm32wl to be published, so until that happens CMSIS won't work.

Hello, I use platformIO for my LoRa Node development. I bougth Seeed-Studio LoRa-E5 Dev board and want to use it with platformio IDE. Fortunately I found your board request but as far as I found this is until now not included in the platformio repository. So I tried to follow your thread but have no success to get my demo working. What I did:

• open a new platformio project with this platformio.ini file `; PlatformIO Project Configuration File ; ; Build options: build flags, source filter ; Upload options: custom upload port, speed and extra flags ; Library options: dependencies, extra library storages ; Advanced options: extra scripting ; ; Please visit documentation for the other options and examples ; https://docs.platformio.org/page/projectconf.html

[env:lora_e5_dev_board] platform = https://github.com/nobodywasishere/platform-ststm32.git board = lora_e5_dev_board framework = stm32cube `

• when I start build I get the following error: `Error: Traceback (most recent call last): File "C:\Users\wolle.platformio\penv\lib\site-packages\platformio__main.py", line 121, in main cli() # pylint: disable=no-value-for-parameter File "C:\Users\wolle.platformio\penv\lib\site-packages\click\core.py", line 1128, in call return self.main(*args, **kwargs) File "C:\Users\wolle.platformio\penv\lib\site-packages\click\core.py", line 1053, in main rv = self.invoke(ctx) File "C:\Users\wolle.platformio\penv\lib\site-packages\platformio\commands\init.py", line 44, in invoke return super(PlatformioCLI, self).invoke(ctx) File "C:\Users\wolle.platformio\penv\lib\site-packages\click\core.py", line 1659, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "C:\Users\wolle.platformio\penv\lib\site-packages\click\core.py", line 1395, in invoke return ctx.invoke(self.callback, **ctx.params) File "C:\Users\wolle.platformio\penv\lib\site-packages\click\core.py", line 754, in invoke return callback(*args, *kwargs) File "C:\Users\wolle.platformio\penv\lib\site-packages\click\decorators.py", line 26, in new_func return f(get_current_context(), args, **kwargs) File "C:\Users\wolle.platformio\penv\lib\site-packages\platformio\commands\run\command.py", line 134, in cli process_env( File "C:\Users\wolle.platformio\penv\lib\site-packages\platformio\commands\run\command.py", line 176, in process_env

============================================================

An unexpected error occurred. Further steps:

• Verify that you have the latest version of PlatformIO using pip install -U platformio command

• Try to find answer in FAQ Troubleshooting section https://docs.platformio.org/page/faq.html

• Report this problem to the developers https://github.com/platformio/platformio-core/issues

============================================================`

• what went wrong?
• where can I find your blinky example?
• normaly I use arduino framework. Is it possible to extend your work also for arduino framework?

Thank's Wolfgang

What's happening is the proper framework package isn't being found. I believe you either need to add

[env:lora_e5_dev_board]
platform = https://github.com/nobodywasishere/platform-ststm32.git
platform_packages = 
    out0f0rder/framework-stm32cubewl
board = lora_e5_dev_board
framework = stm32cube

Or download https://github.com/out0f0rder/framework-stm32cubewl and put it in your ~/.platformio/packages folder (i dont know what it is on Windows)

[nobodywasishere]

Unfortunately i could not get the arduino framework working at this time, so your options are cmsis, stm32cube, and zephyr

thank you for your fast response. I will try your proposal.
