Targets - debugger settings

[0xc0170]

Most of progen targets assume that there is some default debugger set up. We can say it's cmsis-dap debugger. This is not correct and expected, as any module using those targets might change the default one (cmsis-dap is not even documented anywhere that that's default one).
