I don't know if this is still an issue for you, but if it is, do these instructions help?

Setting the config option: Tk1Insecure to True should pass through the correct hardware access. Then "ifconfig eth0 up" should bring up the card.

Subject: [seL4] Passing Network Resource to Linux VM in TK1-SOM

Hi all,

I got a question, how can I pass the network communication to Linux virtual machine? Following the work of seL4-ARM-VMM with TK1-SOM board, i run seL4 as the microvisor that hosts the buildroot Linux as a user-land process, I was able to mount the MMC storage in the virtual machine, but I cannot get the NIC works. I’m wondering has anyone tried it that can give me some hint?

Best Regards
