Yesterday evening I worked on an application for a Nucleo-WL55JC and STM32CubeIDE could connect to the ST-LINK just fine. I closed my PC and this morning started it again. I am trying to upload code to the CM0Plus core and now I am getting the following error:
Target unknown error 32
Error in initializing ST-LINK device.
Reason: Unknown. Please check power and cabling to target.
Things I did to diagnose and solve:
I have checked the USB cable which is perfectly fine
I changed for another USB cable which did not change the situation.
I used a similar Nucleo board which was never used and got the same error.
I checked the settings in the debug configuration. All seems fine.
I tried to access and erase the chip with STM32CubeProgrammer -> THIS WORKS FINE
I made a new project and tried connecting to the chip with STM32CubeIDE. This does not work.
I tried to upload code to the CM4 core and this worked.
Does anyone know how to solve this? I am on a very tight deadline and now I am stuck...
