Dear NXP Technical Support Services,
I have a power supply board that supplies a Lpc4370 and other components of a system. When I measure the resistance between power and GND using a multimeter I get the following readings:
Between 3.3V and GND: 26 Ohms
The 3.3V and 1.2V rails have many decoupling caps around power supply pins of the LPc4370 microcontroller , are they the only cause for this much reduced isolation between these voltages and ground?
The system is running perfectly for couple of days , after running some trace unit testing , the system stops running with keil ulink pro and now i am using the Keil ulink 2 and it was showing swd commmunication failure.
I am using Keil MDK 5.23 version .
Actually the if you know it is from the hardware problem or firware version in keil it was displaying V2.03.
