Hi folks, I finally got a serial console soldered on :) So now I try to use redboot's tftp to yank a kernel across the network.
RedBoot> load -r ramdisk.arm -b 0x00800000
Using default protocol (TFTP)
timeout
I cannot get the poor thing to grab kernels/ramdisks. I've
tried two hosts for the tftpd server, and two tftpds on one
host (atftpd and tftpd-hpa). I've also tried specifying the
local IP in redboot so the packet src wasn't 0.0.0.0.
I can tftpd between other hosts fine, so it isn't
paths/permissions. wireshark shows the packets hitting the
interface, but no attempt is made at responding. Is
something throwing away the packets before they reach
userland? It's not a firewall, maybe the IP stack's spoof
protection?
I notice the dest MAC is set as being the same as the
source. Attached is a wireshark dump of two packets; there
were no replies.
