Re: USB boot, RNDIS issue, can't download image,How to install NAT

actually i thought about porting my own usb rndis to mx21, that's why i
asked.
why it could work on some pc, well it shouldn't.......windows's ethernet
protocol handler don't really need to check if the dest mac address is the
same as the sender's mac......if they check it, it's "careful", if they
don't, it's "trusting the hardware"

Hello, mobilevil

Thank you very much.
I had fixed it according your suggestion.
I set the different mac addresses between PC side and board side.

But I had another question:
Why USB boot could run in some PCs who have the same mac address and some
PCs failed?

same mac??
you should have two different virtual mac address for the usb link
1 for the pc side, another for target board size.
the usb cable actually replace TWO nic card, both your PC and target
board
think that it is controlling a nic card, and talking with another nic
card
you are using freescale cpu? which and which BSP?

some thought
you don't need a default gateway for local area connection 6,
if you have a activesync device plugged in, remove it.
the ip of the target board is 192.168.0.x right?

Hello, mobilevil
I do use different subnet.

Ethernet adapter Local Area Connection:

Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.193.102.254

Ethernet adapter Local Area Connection 6:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.0.4

after plugging in, your pc has a new interface.
maybe you have a 100m ethernet for company network, and you will
have
a
USB
networking device for your target board
use different subnet for your company network and usb network is
better.

Hi,
My device plug directly to my PB machine. and configure the RNDIS
network
use static IP.
my board addr: 192.168.0.2, submask: 255.255.255.0
my pc addr for RNDIS : 192.168.0.4, submask: 255.255.255.0

if your platform builder is in another computer, use windows

if your device plug directly to your platform builder machine,
you
need
to
config a ip address for the usb network interface.
you may see it as local area network 2 or so.

Hello,

software: wince5.

Hi. My eboot uses USB RNDIS to download the OS image into the
target.
The
initialization works, as you can see from the following
output:


Enter your selection: d
INFO: Trying to initialize USB RNDIS.

The problem is the following: I am not able to download the
image
via
Platform Builder, that is, when i click on Attach Device and
the
download
dialog appears, nothing happens. What can I do?

By the sniffing of the netork interface used to connect PC and
target I
can
see:
- target sends broadcast packet on UDP (srcport 980 dstport
980)
- host replys with UDC packet (srcport 1853 dstport 980)
The funny thing is that I tried 3 other pc, and only one (it
is
not
mine
so
i do not know its configuratiuon) works.Any idea?

I heard someone had resolve this problem: it was necessary to
install a
NAT
table on my ethernet nic.

How to install NAT table on nic?

Thankyou very much!
