Hi All,
I am working on Intel I210 based network card for ARM based platform.
I am seeing similar problem what you were experiencing on this mailing list,
where the bus master enable will cause the driver to hang
Can you please let me know if you are able to resolve this issue on Intel
I210.
I have tried disabling Bus mastering after that its able to enumerate
the pci devices but the driver does not get initialized becuase of
the bus mastering. I was reading you previous mail threads on I210
where VDM messages being generated by this I210 Network device for NC-SI
inband
management. I have eeprom dump on X86 Linux OS. Can you please let me know
how to disable this MCTP in ethernet EEPROM. I am using Intel I210 plug-in
pcie card, which works @2.5GT/s and x1 linkwidth.
Thanks in advance.
