Porting on msm7225

[mowgli]

Hi,
We are trying to port android on MSM 7225 hardware. Currently we are
trying to manually bring up the framework. It fails during the init
with the following logs. The service manager seems to die due to
insufficient permissions(Permission denied). The service _manager
binary seems to have execute permission. Any pointers would be much
appreciated.

we have abt 32 MB of RAM free before the framework is started.

strace logs for the forked service manager process:

01:04:26 dup2(10, 0) = 0

01:04:27 setuid32(1000) = 0

servicemanager"], [/* 9 vars */]) = -1 EACCES (Permission denied)
01:04:27 exit_group(127) = ?

The service manager binary seems to have the right permissions:

HI,
I have exactly the same problem when using yaffs2.
Has anyone a solution?

Thanks

where is you /data? this partition must support mmap functionality. Meanwhile, check the existence of cache and other directories in /data, which is created during the 1st time booting and mandatory for booting.

Hi guys

Have you had any success on porting the Android over to MSM7225 ? I
have HTC Jade, and would love to test ride the build releases if you
have any.

Thanks

The problem came from the system and root partition: when using
initramfs for root and yaffs2 for system (as it is prebuilt in
android), we have such problems of binary execution. My solution is to
use jffs2 for root and system, and yaffs2 for data (mmap supported
inside...). No more problem with this combination.

Hello,

The problem came from the partitioning: Now I have rootfs and system in jffs2 ro and application can be launched.

Hi Guys,

Any one succesfully ported android to MSM7225 (T3232) yet? I treid
varous varents and they are detecting the device as Generic MSM7500
and fails.

Thanks
