STLinkUpgrade - 'Upgrade' button greyed-out

[dennis_m]

Hello, while trying to flash some test code, I have to run update on STLink, but the "Upgrade" button is not clickable...?

I have my board connected, I can see is using lsusb command on my Ubuntu...

"Open in update mode" also doesnt give any proper output,

Hello @@dennis_m 

Let me thank you for posting.

For more investigation, could you please provide the Ubuntu and the STM32CubeIDE version.

Thanks.

Did you click the 'Open in update mode' button?

You need to do that first - before you can do the actual update.

Hi,

did you ever update this st-linkV2 with success ?

What kind of st-link - the stick ?

- i am also in Linux system -

after open update mode, you might get :

- then un-plug/re-plug the st-link from usb, then refresh, open update mode again, you get:

- then upgrade, you get

It would be expected that you lose connection while the ST-Link is in Update mode.

Are you sure the ST-Link is genuine?

How to recognize a genuine ST-LINK/V2 versus a cloned one

As @AScha.3 hints, the "USB stick" ones are not genuine.

my assumtion is, that stlink is on board already, basically integrated.. I have I think the original STM32 nucleo board, not the AliExpress one, so I think I dont need eny standalone ST-Link stick...

After executing Open on update mode I am loosing the Stlink in drag/drop menue (as on picture in the very first post), after replugging and refreshin, I get the ST-Link drop down entry again, but the update button is still inactive...

So with nucleo board and onboard st-link it should work.

Try install/use CubeProgrammer, do the update there. (I do it always this way.)

Or just disable in IDE the check for update st-link (standard is always check).

Btw which Version of IDE you use?

with CubeProgrammer it worked, thanks !
