Hello,
since several month we have the problem, that we can't debug our firmware on the RZ/N1 processor anymore. We use the I-Jet debug probe with the IAR-EWB. The problem started with the activation of the SVC call, which is required for RTOS operation.
If the firmware is running free on the system, without a debugger, the SVC context switches work in a timely manner. As soon as we load the firmware in the debugger, each SCV call causes a delay of up to 100ms. This means that the firmware can no longer be tested in debug mode.
My colleague posted this here, but we didn't get any answer:
Any ideas how the SVC interferes with the debug registers?
Regards,
Stephan
