#st-link #st-link-cli #stm32f0
I am trying to connect to my running application and read some variable values from RAM. I am using ST-Link CLI with HOTPLUG option, but the core gets Halted after connect and the RAM content is invalid. The programmer is the on-board ST-Link of an STM32F4Discovery board, the target MCU parameters are included below. Here is my console output:
If I issue a reset everything is OK, but I would like to omit the reset.
ST-Link Utility info:
#st-link #st-link-cli #stm32f0

Upgrading to the latest version of ST-Link CLI solved the issue.
Version info:
Though -sCore still says ''Halted'' but the RAM content is now OK, and the MCU does not seem to be restarting on connect.
