After upgrading from an earlier 5.11.x build (I think 5.11.4) I am getting this error on startup:

LeechDMA: Initialized. (v4)
DEVICE: FPGA: DRIVER_SUPPLIED PCIe gen1 x4 [0,0,0] [v4.17,0500] [ASYNC,NORM,FWCUST]

using VmmSharp (latest nuget pkg)

If i switch back to the old vmm/leechcore, it goes away entirely.

Can you try to update the leechcore_driver.dll as well. For the 2.19 LeechCore version this file was updated as well (I now see I forgot to change the version number on it though, will do), but the leechcore_driver.dll in the package should work.

@ufrisk
Yes, that fixed it.
BTW this updated binary doesnt seem to be in the latest MemProcFS binaries, I had to find it in Leechcore repo.

Oh, I forgot to update the binary packages of MemProcFS with the new files. It's done now. Thanks :)

Nice to see the issue resolved, but I would have expected a good error message if there was a version mis-match between leechcore and the driver, but it seems like that part is somewhat broken.
