My serial on-chip debugging emulator doesn’t respond. Why?

Last Updated:05/17/2017

Question:

Why is my serial on-chip debugging emulator not responding?

Answer:

When a serial OCD interface (debugging through a UART/CSI) is in use, the user must handle communications between the emulator and the target device by programming the debugging monitor program into the exception handler. So the switched exception handler address may cause a communication error between the target device and the emulator. For flexible exception handling, we recommend you use an emulator that supports JTAG connection.

Emulators which support a JTAG connection

V850E2
E1(JTAG)
E20(JTAG)
QB-V850MINIL
