IRQ_F2P interrupt width does not change after apply_board_preset

[Leon]

Hi,
Normally when you instantiate the ZYNQ7 Processing System in Vivado (2016.2) you can enable multiple IRQ_F2P interrupt inputs with:

• Double click on PS7->Interrupts->Fabric Interrupts->PL-PS
• check the Fabric Interrupts and IRQ_F2P[15:0] boxes
• This gives you an IRQ_F2P[0:0] input (note 1 bit wide)
• You then instantiate a concat block and set the output width, say to 2
• Connect the concat output to IRQ_F2P[0:0]
• Click Validate Design. This converts the 1 bit input into a 2 bit input IRQ_F2P[1:0]

The above is as described in https://forums.xilinx.com/t5/Embedded-Processor-System-Design/How-to-use-more-than-one-IRQ-F2P-interrupt/td-p/514661

I have been doing this after applying the old style board presets using:
set_property CONFIG.PCW_IMPORT_BOARD_PRESET   {TE0720-01_a.xml}  [get_bd_cells /processing_system7_0]
and it all works fine.

I am moving over to the new board description files by using:
set_property board_part trenz.biz:te0720_1cr:part0:1.0 [current_project]
...
apply_bd_automation -rule ... apply_board_preset "1" ...

This correctly applies the presets, but the width update of IRQ_F2P does not occur any more. It does not matter even if I correctly set the IRQ_F2P width before applying the preset - it just gets set back to [0:0].

I have tried removing parts of the preset.xml file, but I have to remove the entire <ip_preset preset_proc_name="ps7_preset"> ... </ip_preset> section before the interrupt width is able to be set correctly.

Is there a bug somewhere? Are you able to provide the current set of presets (for TE0720-1CR) as a CONFIG.PCW_IMPORT_BOARD_PRESET so that I can make progress?

Leon

is known issue is being fixed..

[Leon]

OK.
A known issue where: Vivado, .xml?
Who is fixing it: Trenz or Xilinx?
When are they expecting a fix, will it require a Vivado update?

Thanks.

[Antti Lukats]

we are fixing it, the script did change some READ ONLY properties, so they can not be changed later.

Hi,
open the boardpart file TE0720_1CR\1.0\preset.xml with texteditor and delete the following line:<user_parameter  name="CONFIG.PCW_NUM_F2P_INTR_INPUTS" value="1"/>
Recreate the project and the property should be set automatically after validation. We change the board part files this week and upload a new version on our download site.

Thanks - that worked.

I had tried removing this from preset.xml before, but it reads the file earlier in the flow (set_property ip_repo_paths ??), not when the apply_board_preset command is issued, so it had no effect.

Thanks
