I think you may have helped us finding the problem.

I went deeper in our code and found the ALTGX_RECONFIG (or a file called altpcie_reconfig_4sgx.v, which was generated automatically by QII 11.0), and it still appears to be generated by 11.0.

Our design was based on the chaining DMA example coming with the IP compiler for PCI Express v11.0. We added our designs into its framework so we had to use a lot of their IPs, altpcie_reconfig_4sgx.v included. It looks like when we regenerate IP Compiler for PCI Express to v12.1, those design examples were not automatically regenerated.

Will follow this lead and see what happens.
