[U-Boot] [PPC] Internet connection on qemu-ppce500

[vnktux]

Hello guys,

I am running an image of U-boot 2018.09 in qemu 3.0, the goal would be to load an OS-9 rom file from tftp.
The problem is that I can't manage to have an Internet connection in U-boot. No matter how I run the image I always have Net: "No Ethernet found".

I run qemu 3.0 with the following command:

> qemu-system-ppc -cpu e500v2 -M ppce500 -nographic -kernel ~/u-boot -net nic -net tap,ifname=tap0,script=no

I tried to use different -net options in qemu but the problem is always the same.

And from the u-boot source code I have edited the board file qemu-ppce500.c in order to have a few ENV variables (since I can't save any env variables from the running U-boot in qemu).

> ethact=eTSEC1
> ethprime=eTSEC1
> ethaddr=192.168.10.40
> netmask=255.255.254.0
> serverip=192.168.10.2
> gatewayip=192.168.10.254

The image is compiled using of course: qemu-ppce500_defconfig.

What am I doing wrong? Is it even possible to initialize the Ethernet port?

Thanks in advance,
Vincenzo

I doubt that there is a qemu emulation for the TSECs...

Well, if you check the configuration you will see that it has a
plain

	# CONFIG_TSEC_ENET is not set

so the TSECs will indeed not work.  But then, there is

	CONFIG_E1000=y

It would have been helpful if you had included the actual boot
messages of your system.  There should be some E1000 network
interface visible...

Best regards,

Wolfgang Denk

You can do this in a number of ways.     IBM chose to do all of them.

It goes without saying, that the satellite broadband often costs more than
fixed line broadband deals and set up costs are between ?100 to ?400. Prices
for satellite broadband tend to vary between ?20 per month to ?100 per
month. Satellite broadband deals also often have restrictive download limits
and those seeking a more generous allowance will have to pay extra. These
aren't the all cons, which it has, more can be written on 
https://usave.co.uk/ <https://usave.co.uk/broadband/satellite-broadband/>  .
If the Wachusett Brewing don't solve these problems, his project is doomed
to failure.
