The board we designed using MPC5777C encountered the following errors in the first debugging, and the measurement reset pins were always low:
1、“The target may have entered resetescalation. Please power cycle the board.”
2、“Warning: Device is not detected or may be censored. Please check connections or please enter password in GDB server parameters within debug configurations using the flag-uncensorpassword=n, then restart the debug session.”
The following is the log during the debugging process:
Connection from "127.0.0.1" via 127.0.0.1. Connection from port "65300" to 7224
