Hi,
I connected my brand new STM32F769I EVAL board to power and to PC through USB ST-Link port, I opened STM32CubeProgrammer, picked ST-LINK connection on the top right, clicked Connect, and it said that I need to perform a firmware update first. So I click Firmware upgrade, and the ST-LINK/V2 is recognized in the Upgrade tool, so I perform an upgrade successfully.
But now after restarting the device and going back to CubeProgrammer, the drop down menu next to the Serial number under ST-LINK configuration says "No ST-LINK detected". I tried pressing refresh but it didn't help. If I click Firmware upgrade, the ST-LINK/V2 is detected in the STLinkUpgrade window, and I see a valid ST-Link ID, but clicking on Open in update mode now results in an error: Error connecting to device ST-LINK/V2 (error 0x21); check the USB connection and refresh the device list. I tried disconnecting and reconnecting the USB, refreshing the device list, switching to another USB port, all to no avail. Again, it detected it successfully a few minutes prior to that and performed a successful firmware upgrade.
I have STM32CubeProgrammer v2.6.0.
Any help is appreciated.
