- Subject: [ECOS] RedBoot in Little Endian Mode
Hello Guys!
I has IXDP425 board, and should running her in Little Endian mode.
I download redboot BE and LE ROM image from Intel, but has some trouble
with NPE network card working in LE mode.
In BE mode NPE cards work fine, but in LE mode network is not working
correct.
BE image is writed successful on the flash and worked, but in LE image i
swap words before writing to flash.
I set mac_address for npe_eth0: 00:30:30:30:30:30, configure npe_eth0 as
primary network boot interface and run tcpdump
on host connected to same hub.
Then i reset board, and tcpdump show me strange result, instead my mac i
see some other mac, and instead bootp protocol, i
see some other protocol(see below).
I think that is BE/LE mode trouble with NPE support in redboot from
Intel. (Or i mistake and problem in something other?)
Maybe already exist native version RedBoot from ECOS with correct
support NPE in Little Endian mode ?
root@nickolay:~# tcpdump -i eth0 -n
tcpdump: listening on eth0
