ipxe.efi with embedded scirpt hangs, precompiled ipxe.iso works, compilation errors - kmwil - 2017-02-22 11:55

Hello,

I installed rEFInd on iMac (I believe it is Late 2013 or newer, Model A1419, EMC 2639) and compiled/embed my script to boot the specific Linux kernel. This setup worked fine until we had to upgrade to OS X Sierra. Now, something is wrong. Previously compiled ipxe.efi don't work anymore.

The Ethernet card is net0: BCM 57766, so the driver should be tg3.

To solve this issue i downloaded newest ipxe from git, compiled it and embed
a script.

Code:
#!ipxe                                                                          
                                                                                
ifconf --configurator dhcp net0                                                
kernel /blah/vmlinuz-lk net.ifnames=0 biosdevname=0 root=/dev/nfs ip=dhcp  
boot

Effect: everything hangs after selecting ipxe.efi from rEFInd.

When I embed shell script:

Code:
#!ipxe
shell

I get the shell. When I type something interface related (like dhcp or ifconf shell hangs). ifstat works fine.

And now: when I use precompiled ipxe.iso from your site it works fine. Card is up and running.

So I compiled the shell with tg3 DEBUG flags:
Code:
make bin-x86_64-efi/tg3.efi EMBED=shell.ipxe DEBUG=tg3:3,tg3_hw:3,tg3_phy:3

Effects:
Code:
Link is down
allocated iob_buffer for descriptor 0
...
allocated iob_buffer for descriptor 7

And here hangs...

Also, I cannot compile with all flags: I get errors like this:

Hello Kamil,

might this be related you think?

What do you mean by "all flags". I am able to compile using the make line you posted without an issue (make bin-x86_64-efi/tg3.efi EMBED=shell.ipxe DEBUG=tg3:3,tg3_hw:3,tg3_phy:3).
