Tool/software: Code Composer Studio
After the latest CCS update (Nov 8 2020) I am starting to see debugger problems, specifically:
Cortex_M4_0: JTAG Communication Error: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.2.1.00042)
Cortex_M4_0: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
Sometimes resetting the DAP or debugger or the entire toolchain (CCS, computer) it gets going again but I am not convinced any of these are not just a monkey trick. When it fails, my target board restarts with the onboard code which I can connect to (connect target). If I show all cores the Probe/IcePick_C is off line (not surprisingly).
I cannot quite figure out what causes this and/or how I remedy it.
