That is a good information, thank you.Maybe this is what makes the difference:M33_Cross_Trigger_Interface.gifThe mapping between debug triggering events and debug channels is programmable.
Usually this is managed by debug tools. In single processor systems, the CTI component is
unlikely to be present. In the previous generation of Arm processors, the CTI components
were outside of the processor, but are now integrated as optional components to make the
design of the system easier.
I will do more experiment and write back the important result in this forum, including my previous finding about SWD does not work properly when the MCU in bootloader mode.
