Problem with programming Lora discovery kit

Having a problem with ST-Link v2-1 programming the STM32CubeExpansion_LRWAN boards.

Have updated the firmware and using the latest driver for WIndows 10.

Programming requires constant driver restarting. Debugging from the IAR or Keil is nearly impossible.

On the several PCs the app ST-Link Utility can't connect to the board due to a USB failure.

Drag-and-drop feature works 1 time out of 100 with fail message: 'The application file format is unknown and cannot be parsed and/or processed'

Thanks for help.

Have you disabled low power modes in your code? If the chip keeps turning off it is hard to connect too, or program.

Define LOW_POWER_DISABLE

Current firmware for the ST-LINK is J30 as I recall

Thanks, the LOW_POWER_DISABLE.wasn't enough. I had to uncomment DEBUG as well since debug pins are shared with GPIO functions.
