Re: Download OS image to target with USB RNDIS

Tech-Archive recommends: Speed Up your PC by fixing your registry

On the menu choose Target and then Connectivity Options

For the "Target Device" choose the device that matches the one you have connected.

"Download" should say "Ethernet" Then click settings. When the bootme is sent your device name "MAINSTN8192" should appear in the active devices list. Does it? If it does, select it.

If it does not you may not have the PC-side RNDIS driver installed correctly. To check this attach the device and begin booting. Then look in the "Network Connections" dialog. While the bootme message is being sent there should be a network interface with the "Device Name" of "Microsoft Windows CE RNDIS virtual adapter" (4th column on my computer). If not you will not be able to boot.

To install the driver check out
PUBLIC\COMMON\OAK\DRIVERS\ETHDBG\RNDISMINI\HOST\usb8023.inf and PUBLIC\COMMON\OAK\DRIVERS\ETHDBG\RNDISMINI\HOST\howto.txt

If the driver is installed and you still don't see "MAINSTN8192" on the active devices list you need to make sure the IP address your bootloader uses is in the same subnet as your bootloader, but not the same IP address. I don't see your bootloader IP address in the output, but sometimes this is hardcoded in the bootloader to be 10.0.x.x.

Hope that helps,

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:

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)



Thank you
