"No ST-LINK detected" Linux (cachyOS) for new installation

[mrjordan]

Hey all, just installed STM32CubeIDE on cachyOS and connected my HiLetGo STM32F103C8T6 dev board (https://www.amazon.com/dp/B07VKSVM21), and the IDE is giving me the following error when I try to debug or deploy:

I tried installing ST-LINK-SERVER separately just to be safe, and it said that it was already installed. (I assume as part of the Cube IDE installation.) Also reinstalled libusb (Version 1.0.29-1.1).

I can see STM32x_USB under Removable Devices in the system browser when plugged in, so I know the board is connecting at least. Any ideas here?

So do you have a ST-Link?

[mrjordan]

You know what? Nope. Didn't realize until just now it was a separate
physical thing I needed to acquire.

Thanks! :grinning_face_with_sweat:

If you buy a knock off programmer that likely won’t work well either. The boards you bought almost certainly contain counterfeit chips. They can work, but you are rolling the dice. Consider if the discount is worth your time.

It’s generally better to stick with genuine parts. A NUCLEO-F103RB board is cheap and has a built-in ST-Link programmer.

Welcome @mrjordan, to the community from my side as well!

The product you are using is a so-called Blue Pill since years only containing clones of a genuine ST product. As @TDK already said, the seemingly small price advantage quickly evaporates, because, as @Pavel A. mentioned, you also need an ST-LINK. If one or both contain illegal clones, as the colourful tin cans do as well, you end up frustrated forever with tools that don't work as expected – completely overlooking the fact that these are not original ST products, but counterfeits.

To get the support you need, please contact the third party you purchased this product from.

For assurance of buying authentic ST products, we recommend purchasing exclusively through our official distributors, which you can find listed here: ST Official Distributors.

And adding to what other posters already mentioned ...

All Linux distros I know support the ST-Link out of the box, you don't need to install any drivers.
Cachy OS is most probably no exception.
Just connect a ST-Link, and type "lsusb" in a command line.

You will need to add you user to certain groups to be able to use it, though. Normally toolchain installers do this for you, but I'm not sure about Cube, and your distro. Group names differ somewhat between Linux flavours.
Worst case you might need to do it manually.

Hi,

Aside from the question of whether your board might have a STM chip or not, do you have a st-link at all ?

Because you wrote: > and connected my HiLetGo STM32F103C8T6 dev board < , which is just the target board, without st-link on board . Without st-link no debug connection possible . (or other, like j-link, cmsis-DAP , etc.)

Thanks, all!!

And noted, I had in fact ordered one of said colorful tin cans off Amazon yesterday after hearing that there was no ST-LINK on this board. Just cancelled that and ordered and official device directly from ST-LINK, I had no idea there was a difference so I appreciate your assistance here.

You've all been so much more helpful than other communities I've been part of in the embedded space. Greatly appreciate it.

Which groups tho?

Usually dialout and/or plugdev.

Try 'groups <your_user>'.
