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.

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?

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