IP components used in the design have conflicting settings. Intel PCIE Ftile MCDMA

Question

I generated a 4x4 PCIE MCDMA using the ip designer using quartus 25.3.0.109 from the example design from https://altera-fpga.github.io/rel-25.1/embedded-designs/agilex-7/m-series/pcie_rp/ug-pcie_rp-agx7m-hbm2e/#pcie-bam-interface. I then switched my design to use a 1x16 port and I got this error.

Error (21842): Support logic cannot be generated because IP components used in the design have conflicting settings

Hi BeJamInThank you for reaching out to us.Could you please regenerate the MCDMA IP from scratch using the 1x16 IP mode configuration? Instead of modifying the existing 4x4 MCDMA IP, please create a new MCDMA IP instance in Platform Designer and select 1x16 during the initial IP configuration. The reason for this recommendation is that changing the IP mode from 4x4 to 1x16 through the GUI may not fully reset the internal parameters associated with the unused sub-cores, which could lead to unexpected behavior.Please let me know whether the issue persists after regenerating the fresh IP for 1x16 mode configuration.Thanks.Best Regards,Ven&nbsp;
