I've been having difficulties using the MCUXpresso v11.0.1 debugger with a LPC55S69 evaluation kit (which has a revision 0A processor). It worked fine with v11.0.0.
I notice that the v11.0.1 release notes mention that "Updates to allow LinkServer debug connections ... mean that some pre-production LPC55S6x silicon can no longer be supported."
Does my revision 0A processor count as "pre-production LPC55S6x silicon"? If so is there any workaround to allow me to use the v11.0.1 IDE/debugger with my old processor?
MCUXpresso v11.0.1 doesn´t support pre-production LPC55S6x silicon as you mention, unfortunately, there is no a workaround, for an old processor you need to use MCUXpresso v11.0.0.
Have a nice day!
