Hi Ivan,

Thank you for your reply.

Yes, I managed to boot up l4linux in QEMU. However, on real machine, I have no clue why the prompt doesn’t show up (I used the same binary and config file as in QEMU). Since I don’t have double COM-ports right now (all our machines come with only one COM port), I can’t see what’s happening on the l4linux side. As you said, the Genode side log seems right.

Is there anything you could suggest other than putting two COM-ports to find out what went wrong?

Best,

Jilong

Hello Jilong,

This log seems good. These messages aren't critical error, they are warning.

In l4linux script qemu must redirect first UART to file, this file contains genode debug log (this log), second UART redirected to console, it's l4linux console. If you use real hardware you need connect two COM-ports to your target, COM0 for genode log and COM1 for l4linux.

Hi,

I was trying to run l4linux on Genode following the online tutorials. Compiling was fine. I didnt change any configuration file or script. Everything was in default setting.

I failed to boot up the l4linux using either emulators (QEMU, Virtualbox) or a real machine. It just hangs during the boot process and I observed multiple error messages (quota exceeded, illegal announcement of service " Uart", Cannot determine physical address for dataspace Binary! etc).

I attached the log file of a typical run on a real machine (Intel Core i7) for your reference. I hope someone could spot some problems in it.

Thank you very much!

Best regards,
Jilong
