...from Patrick's repo, .Syslinux.efi is downloaded, there is an ARP and then nothing hits the wire from the client. The internal failing scenario is core_udp_sendto in syslinux calls Udp4Configure BIOS command, (I will grab the packet.) BIOS returns an EFI_UNSUPPORTED (EFIERR (3)) error but tftp_open still tries to transmit a packet and waits for a reply (core_udp_recv). The loop timeout values are long enough that the watchdog eventually times out and reboots the client. In tftp.c (tftp_open) starting at line 240: sendreq: timeout = *timeout_ptr++; if (!timeout) return;...

from: Jeff Sloan <jeff_sloan at selinc.com> Based on commit: 9314e330 Setting UseDefaultAddress to TRUE uses invalid StationAddress and SubnetMask values. This is in a network with a local TFTP/MTFTP server. If the server is local, on the same subnet, UseDefaultAddress is set to false and the client ip and subnetmask are loaded, otherwise set UseDefaultAddress to TRUE. This is added to

Hello, I tried to boot the new syslinux.efi (32bit) from the released syslinux 6 via PXE. In a wireshark trace I can see that the syslinux.efi was loaded successfully via TFTP. Then the client try to load ldlinux.e32. I see the request and also the acknoledgement in the trace. After that the client try to load the file, but the source port is changed to tftp request port + 1. For example:
