DFU Broken after STLink upgrade (FIXED)

[BBeck.1]

IDE suggested that I upgrade STLink FW on my STM32MP1-DK2 discovery board. Now when I connect my Linux PC to USBC on DK2, device isn't recognized by STMProgrammer (also nothing shows up in dmesg).

Hi @BBeck.1​ ,

There's no relation between ST-Link and USBC on DK2.

It's 2 different physical ports on board and drivers on PC side.

When you say IDE ? You mean STM32CubeIDE ?

>> USBC on DK2, device isn't recognized by STMProgrammer

Using CubeProg GUI ? Do you select USB as device for connection ?

Do you set boot switch to 00 for serial boot ?

Could you send a screenshot ?

>> also nothing shows up in dmesg

This case you mean with SDCard boot.

Nothing display on ST-Link Virtual Com Port console, right ?

But does the boot looks to happen with demo launcher displayed on sreen ?

Thanks

Olivier

Thanks. Yeah, I hadn't plugged in the OTHER usbc port (which is the DFU) on the DK2 board. Anyhow, it was coincidental that The Cube IDE prompted for ST-link upgrade.

I appreciate your response.

Cheers,

Ben
