I wrote a sample app starting from the 'UART Echo Back' source for the 21489 EzBoard.
Starting it from VisualDSP I have no problem.
Then I moved into the CrossCore Embedded Studio, defining a debug configuration and changing the interrupt() function with the adi_int_InstallHandler() calls.
If I launch the app I receive he following fatal_error:
A non-recoverable error or exception has occurred.
Description: No dispatched handler available for the specified interrupt code.
General Type: RunTimeError
Specific Type: NoDispatchedHandler
Error PC: 0x00124446
Which is the 'specified interrupt' ?
If I run the step-by-step mode I do not have the error
PS: i modified the code that configure a couple of GPIOs as input pins since they are connected with buttons.
I used the code 'Configure a GPIO input' i found among the installed examples.
It uses some adi_gpio_* functions that doesn't exist for 21489.
