Hi Its realy strange after using STM keil license for M0 devices for a while and uninstalling that license, no device appears in my device list in keil. even after re installing the software and installing different device packs. Anyone knows how to solve this issue?
The STM Cortex M0 license had not been uninstalled successfully. I followed following link and the problem is solved now:
