Figure 9-5. All Debugger RJ45 MCU Target Side interface Pinout
Problem 19: Programming works, but not the debug.
•
In programming mode, the programmer supplies the clock necessary to erase and program the target through
the ICD4 PGC/TCK/SWCLK signal interface. However, in Debug mode the MCU oscillators must be running.
If MCU system clock source is not working (POSC, XOSC, XOSC32, FRC and so on) your debugger will not
function. Check clocks sources and user clock configurations.
