iPXE and USB-C

[speleo14]

Sorry for the long post...

(2017-01-13 18:13)NiKiZe Wrote:  The usb drivers is not included by default in the ipxe build,
so with something like:

Code:

make bin-x86_64-efi/ipxe--ecm--ncm.efi DEBUG=xhci

OK, I tried that.
I used ipxe-26050fd and built with "make bin-x86_64-efi/ipxe--ecm--ncm.efi DEBUG=xhci".

And this is the ouptut for different nics:

Different build, without the --ecm--ncm: "make bin-x86_64-efi/ipxe.efi DEBUG=xhci"
Same outcome for everything except
Apple USB-C-USB-A adapter, Apple USB-A nic, where I get:

Code:

And now it gets weird: I also tried an older build (ipxe-fd95c78) from november 16 (built with "make bin-x86_64-efi/ipxe.efi"), and this one works, but only sometimes. Sometimes it doesn't, and I also get the "No configuration methods succeeded" error... I'd say it works for around once in 5 or 10 times.



EDIT: about the ifstat, it seems as if I can't get into the iPXE command line. Nothing happens when I press ctrl-B.
