Hi,
when running L4Linux/L4Android on the Beagleboard (rev. C4), only 128MB of 256MB RAM are detected by the bootstrap process.
Here [1] you write that the older Beagleboard has only 128MB, so this is default setting.
As described in that thread, I tried to create the Makeconf.boot file, and it works so far (image is build with 256MB RAM), but still only 128MB are actualy detected (limited by scan):
L4 Bootstrapper Build: #30 Di 6. Sep 14:38:47 CEST 2011, 4.5.1 Scanning up to 256 MB RAM Memory size is 128MB (Limited by Scan) (80000000 - 88000000) RAM: 0000000080000000 - 0000000087ffffff: 131072kB Total RAM: 128MB
Please see [2] for the full bootstrap log.
I already tried to adjust manually the support.h and startup.cc file in the src/l4/pkg/bootstrap/server/src directory, resulting exactly the same issue.
By the way, I think this is causing L4Android to fail during boot, since memory is not correctly allocated:
android | l4x_setup_memory: Can't get main memory of 256MB! MOE: mem_alloc: quota: limit=-1 Byte, used=11572080 Byte MOE: mem_alloc: global: avail=57008128 Byte android | Terminating L4Linux. mag | GC: step this=0x108d220 _life = 0x13228 mag | GC: object=0x13228
Thank you for your help so far!
Regards Giorgio

I suppose u-boot is saying 256MB?

What did you change? You removed the scan-function and hard-coded 256?

Even if the overall system would have 256MB of RAM, how could a single program/VM alone get that amount?

Yes, you're right. Indeed changing the boot args for l4android solved the issue.

Thanks Giorgio

The same can be achieved by adding RAM_SIZE_MB=256 RAM_BASE=0x80000000 to the command line when building the image or it can be added to conf/Makeconf.boot for a default setting.
