| mne | Hi, I just tried to build a root image using the script available at https://wiki.ubuntu.com/ARM/RootfsFromScratch. Unfortunately, it failed: http://rafb.net/p/aVOgpS89.html | 13:26 |
|---|---|---|
| ogra | Failed to fetch http://ports.ubuntu.com/ubuntu-ports/dists/jaunty/Release.gpg Could not resolve 'ports.ubuntu.com' | 13:27 |
| mne | The reason for this seems to be that qemu's network is not connected to the ... | 13:27 |
| mne | yes. What should I do so that the qemu image can connect to the world ? | 13:27 |
| ogra | it does use an internal NAT by default | 13:27 |
| ogra | so if your host is connected properly qemu will as well | 13:28 |
| mne | That would be fine. However, while the ubuntu machine on which I run the script has network connectivity, the qemu image still doesn't | 13:28 |
| ogra | do you use any http proxy ? | 13:28 |
| mne | no | 13:28 |
| mne | Also there is no firewall or anything else. On the machine can ping, apt-get update, apt-get upgrade and all these things | 13:29 |
| mne | However, the ubuntu installation is running inside a vmware if that matters | 13:30 |
| mne | the network interface is bridged so that it has full access to the LAN | 13:30 |
| ogra | hmm, that might be it then | 13:30 |
| ogra | 1144 to 1168 show its properly configuring the network | 13:31 |
| ogra | your vmware might not hand over dns data here | 13:31 |
| * ogra has never used the script inside a VM ... i surely know it works on a native setup | 13:31 | |
| mne | does the script set up its own dhcp server ? The 10.0.0.0 network is not on my lan. | 13:32 |
| ogra | no, thats qemu's default setup | 13:32 |
| mne | I'll have a look at the qemu config. So far I just installed it but did not change the default config | 13:33 |
| ogra | 10.0.2.15 is your host ... 10.0.2.0 is NATed | 13:33 |
| ogra | vmware is blocking something here | 13:33 |
| mne | is there some test image I could run in qemu to explore the situation ? | 13:34 |

| Martyn | Afternoon all | 19:57 |
| Martyn | Does ubuntu have to do anything special to deal with TrustZone? | 19:57 |
| Martyn | i.e. does it run untrusted, or does it have to run certain things through TrustZone? | 19:57 |
| suihkulokki | is TrustZone even publicly documented? | 19:59 |
| Martyn | Yes, sort of. | 20:00 |
| Martyn | Since it performs a kind of virtualization, in order to access certain hardware you kind of have to stop the entire kernel context, reach over through TrustZone ... | 20:00 |
| Martyn | Linux based phones like the Motorola A1200 and others, must be making use of it somehow... | 20:01 |
