Hi everyone,
My company recently purchased a new ST-Link/v2 programmer. The problem is that after the firmware update, the device stopped working, and when I press the Connect button on the STM32CubeProgrammer, the following error appears:
Error: ST-LINK error (DEV_USB_COMM_ERR)
I tried using an ST-Link/V2 programmer I bought a few months ago, and everything works fine (I only replaced the programmer, same USB cable, same programming cable).
The programmer is original, I'm sure of it. I purchased the programmer from DigiKey.
Even the serial number I see appears to be genuine.
When I try to update the firmware, I get the following result:
Can anyone help me solve my problem?
Thanks
