Hello,
Everything was fine yesterday, but when trying to download a project im working on today I am getting the above error.
Any ideas? no settings have been changed, its weird.
Can you mass erase a chip or use drag and drop programming to reflash it? Does it work?
You can conenct to that chip via pyOCD and run test scripts to check if everything is correct. That might help to get the chip to a “normal state”.
