Message-ID: <1578048053580.44338@1und1.de> (raw)

Hello DPDK team,

I have 2 Mellanox ConnectX-4 MCX415A-CCAT cards connected with DAC (firmware 12.26.4012). Im using debian stretch and DPDK 19.11.
If i try to start DPDK-applications i get the following error:

sbernauer@he37:~$ lspci | grep Mellanox

I can't find a description of the error code -12, can you please give my a hint whats my problem?

Thanks a lot!
