Error: No STM32 Target Found - But only in CubeProgrammer

[raridi]

Hello, I've been using the Nucleo-F446RE to program a stm32f4 series chip using the Nucleo's onboard ST-link capabiltiies. So far I have managed to get it to link and work in CubeIDE, but in CubeProgrammer it's giving me the following issue (attached screenchot): 

This is strange as my hardware setup works for CubeIDE, but not CubeProgrammer? As another bit of info, I had to go to a slightly older revision of CubeProgrammer and IDE for my current project, but before switching to this older version my CubeProgrammer was able to connect to my setup with no issue and the same settings. 

Any guidance or tips would be greatly appreciated.

Make sure the onboard target is physically disconnected via jumpers.

Make sure new target is powered and functional and correctly connected.

As it's worked before not clear why it no longer works or what changed.

Perhaps diagram exactly what's wired

Identify the versions of things that did and did not work.

Make sure NRST is connected so "Connect Under Reset" can function.

If you suspect code on the F4 is changing PA13/PA14 pin functionality or powering down, strap BOOT0=HIGH to stop your errant code running.
