unable to initialize adapter 1code c86a2002

After i tried to change the mac address with the eeupdate64e tool,i could no longer update the mac address or the firmware again,use bootutil to check that the mac address is 0. how should i solve this problem and how to avoid this problem again?

thanks.

Hello @Flying_pig,

Thank you for contacting Intel Embedded Community.

Looking internally about this error code, can you enable "Bus Master Attribute for DMA transcation" in PCIE/PCI Configuration from the BIOS?

Hello@Diego_INTEL

 Thank you for your advice,I will try it,If i can,What should i do in the future?

Should i use this bus to clear all the contents of flash and then burn the new firmware?

If so,What exactly should i do?

Best regards
