I can't connect to my STM32MP157 evalaution board. I have installed required libraries as decribed in the tutorial: https://wiki.st.com/stm32mpu/wiki/STM32MP15_Discovery_kits_-_Starter_Package 5.1 Installing the STM32CubeProgrammer tool. However I get the following error:

Hi @KZura​ 

I suspect a problem with the USB/DFU driver.

Did you go through 5.2 Preparing the USB serial link for flashing also ?

Are you working with Windows or Linux host machine ?

Hope it help

Hi OlivierG, thanks for your reply.

Yes I have went through 5.2 Preparing the USB serial link for flashing step.

I am using Linux 16.04 host machine.

What else could I provide to track this issue down?

Thanks!

Not the original poster, but I have the exact same issue.

Command is "STM32_Programmer_CLI -l usb"

Output is:

                       STM32CubeProgrammer v2.4.0
