Hi Markus,

I asked our compiler engineers but they're not sure why not detecting that this is a valid target. Can you please post the output of "/proc/cpuinfo"? This is what we use to determine the target processor.

Thanks,
Mat

Hi Mat,
unfortunately the file /proc/cpuinfo is empty on the device. I have made a ls in the proc folder:

# ls -l
dr-xr-xr-x root root 2012-09-11 07:20 uid_stat
--w--w---- root system 0 2012-09-11 07:20 sysrq-trigger

-r--r--r-- root root 0 2012-09-11 07:20 pagetypeinfo
....

You can see that most of the files in the proc folder are empty.

Regards
Markus

Hi Mat,
i am very sorry but it was a mistake. I testeted it only with vi. In vi the file is empty but if i do cat /proc/cpuinfo i get the following answer.

# cat /proc/cpuinfo
Processor : ARMv7 Processor rev 1 (v7l)
processor : 0
BogoMIPS : 4.80

processor : 1
BogoMIPS : 4.80

Features : swp half thumb fastmult vfp edsp neon vfpv3
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x2
CPU part : 0xc09
CPU revision : 1

Hardware : riogrande
Revision : 0000

May be this can help to solve the problem.

Markus

This is the problem. Looks like Sony uses there own code names for the chip. If we got you a work around, do you mind testing it for us?

Thanks,
Mat
