EDK, reset module, interrupts

Hello,



assembling an EDK 3.2.2 design I encountered some difficulties:


  1. The peripheral reset signals of the Processor System Reset Module are not assigned properly. I declared a peripheral reset port of width 3 in the MPD file: C_NUM_PERP_RST = 3 and assigned the modules reset signals to the port in the MHS file PORT Peripheral_Reset = module1_reset & module2_reset & module3_reset

The auto-generated system.vhd file contains the lines: peripheral_reset_vec(0 TO 0)

Hi Christian,

yes I solved it. What you have to do is making a dummy driver. At this moment, I guess, your opb device is using a generic driver. In the mss file you have the following line for your opb device:

PARAMETER DRIVER_NAME = generic

The generic driver doesn't have a "INT_HANDLER" parameter. So you can't use this parameter in your mss file. To use the "INT_HANDLER" parameter (in order to assign your interrupt handler) you have to make a dummy driver. This driver only exists of a mdd and tcl file. You can see examples of them in your install directory of the EDK.

This is a bug and it's fixed in EDK.6.2. To work-around your issue you can insert IP pcore. That takes the bus as input and splits it into individual bits as outputs.
