Hi Folks,
I have write my own peripherals for NIOS and they are working successfully. Yay. However I need to declare them as accepting pre-emption, I have the VIC core and so far the peipherals jum to their ISRs but it appears that one will not interrupt the other if pre-emption is not enabled, even if the priority levels are set. On reading the developers handbook and the build tools ref I think I am supposed to add a line in the hw_tcl. However when I add the line: set_sw_property isr_preemption_supported true I get an error, I also tried preceding with: create_sw_package test I am not really sure how to do this, could someone offer some advice please? deBoogleLink Copied

The set_sw_property statements go in the _sw.tcl not the _hw.tcl. Can you try adding it there and see what happens?
