Hello. I have a Nucleo-G474 and I want to bypass the onboard STLINK-V3 programmer and use an external programmer module (STLINK-V3MODS). I have the proper connectors and ribbon cables to connect to the MIP10 connectors.
The program sees that the device does have 3.3 volts and it does see the STLINK-V3MODS module. However it does not see the target. Below is the message.
I've tried all sorts of things, like moving jumpers around to disable the onboard ST-Link. I removed some of the 47 ohm resistors that could interfere with the external programmer. I can't find any information on how to use an external programmer with the Nucelo-G474 board.
The reason for this exercise is that I am not going to use an onboard ST-Link programmer in my application. I need to use an external programmer and I want to ensure that I have a working design to do this with.
Thank you, Richard V
