Is there a preferred way to flash STM32 Nucleo board with stlink?

[MarekSzczypinski]

Hi guys, I'm still wrapping my head around the labgrid. For this I'm setting up my small "device farm" to try the idea of remote access to MCU boards. My farm is an old laptop with some boards attached to it via usb cables. Some boards are arduino nano, some STM32Nucleo and a Raspberry Pi.

Unfortunately I can't find an example of using labgrid to flash a *.bin file to a STM32 Nucleo board either using stlink or the STM32Cube Programmer.

Same goes for flashing arduino board with prepared *.hex file using avrdude

I have found the FlashScriptDriver, but I still am not sure how to use it.

Any advice on how to approach such a task? If I've missed some place in documentation or example that explains this please point me to the right place :-)

We use labgrid with boards running Linux, so we have tools like imx-usb-loader, which may be the closest equivalent to stlink or avrdude. These are supported via as Drivers: https://github.com/labgrid-project/labgrid/blob/master/labgrid/driver/usbloader.py

Perhaps the Driver for flashrom is even closer to what you'd need: https://github.com/labgrid-project/labgrid/blob/master/labgrid/driver/flashromdriver.py

So to support these boards/MCUs in labgrid, you'd have to write corresponding Driver and Resource classes.

Oh, I see. Do you consider expanding labgrid's functionality to MCUs?
I'll try to look at the flashrom and flashscript. Maybe I'll get some ideas.
Thank you for reply and explanation.

Since we @pengutronix don't have the micro controller or RTOS use case, we won't implement such things ourselves. But we're always happy to discuss architecture, drivers and resources before they get implemented.

There's also #1140 for sharing/linking MCU use cases.
