LAUNCHXL-CC1312R1: How to prevent IcePick from halting the MCU after a reset

hugo L

Hello

I am trying to do a software reset with SysCtrlSystemReset().
I use LAUNCHXL-CC1312R1.
I am aware that the MCU halts after a reset if a debugger is connected.
I have read the following threads:
e2e.ti.com/.../855972
e2e.ti.com/.../816859
e2e.ti.com/.../839798

However, I experience the same behavior after communicating with the JTAG, either flashing, resetting or debugging (I use openocd, openocd no longer running).
Is there a way to prevent this behavior?

Thank you

Please note that we are looking into this, and will provide feedback as soon as we have consulted the correct people.

We can reproduce what you are seeing, but I need to figure out if this is expected behavior by design, or if this is a problem with the debugger.

Try to add the following in your code before you do the reset:

HWREG(0x40090030) |= 0x00000800;
CPUdelay(16 * 64);
HWREG(0x40090030) |= 0x00000100;
CPUdelay(16 * 64);
SysCtrlSystemReset();
