FWIW, I am able to use certain commands from the SDK image in Harmattan proper just by pointing to different libs. This is how one can use brctl, lvm, iwconfig, etc. without compiling for Harmattan.

For example, I can use lvm with loopback images to add space to a chroot based on dd image files without having to recreate the image. Very flexible. I'm converting an Ubuntu chroot to an LVM-based one now.

I was also trying hostapd with this method, but there still seems to be issues.

I wrote a script that wraps any command to one in my sdk image. It uses the symlink name to proxy to the real command. Here is the contents of my /root dir:

Code:
 
RM696-21-3_PR_006:~# ls -l
total 40
lrwxrwxrwx    1 root     root             6 Apr 30 07:13 brctl -> sdk.sh
-rwxr-xr-x    1 root     root            61 Apr 18 07:44 brctl.bak
lrwxrwxrwx    1 root     root             6 Apr 30 07:53 hostapd -> sdk.sh
-rwxr-xr-x    1 root     root            63 Apr 19 14:51 hostapd.bak
lrwxrwxrwx    1 root     root             6 Apr 30 07:12 iwconfig -> sdk.sh
-rwxr-xr-x    1 root     root            60 Apr 18 07:32 iwconfig.bak
-rw-r--r--    1 root     root           151 Apr 23 21:10 mount.m5sdk
-rw-r--r--    1 root     root           210 Apr  5 08:09 mount.precise
-rw-r--r--    1 root     root           127 Apr  4 08:02 mount.sdk
lrwxrwxrwx    1 root     root             6 Apr 30 07:05 pvs -> sdk.sh
drwxr-xr-x    3 root     root          4096 Apr 19 08:07 sdk
-rw-r--r--    1 root     root            55 Apr  4 07:58 sdk.conf
-rwxr-xr-x    1 root     root           219 Apr 30 07:11 sdk.sh
drwxr-xr-x    3 root     root          4096 Apr 19 08:04 ssk
Here is the proxy/wrapper script:
Code:
RM696-21-3_PR_006:~# cat sdk. sh
#!/bin/sh

EXEC=$(basename ${0})

#point to SDK from here on out
export PATH=/sdk/usr/local/sbin:/sdk/usr/local/bin:/sdk/usr/sbin:/sdk/sbin:/sdk/bin
export LD_LIBRARY_PATH=/sdk/lib

#/sdk/usr/sbin/brctl "$@"
$EXEC "$@"
And here some examples in action:

Code:
RM696-21-3_PR_006:~# ./brctl show
bridge name     bridge id       STP enabled     interfaces
RM696-21-3_PR_006:~# ./pvs
RM696-21-3_PR_006:~# ./iwconfig

Hm, Am I missing something here. Tried to flash your kernel (full flas) on my N9 (PR1.3)
flasher -F img.bin -F emmc.bin -k zImage_2.6.32.54btlc-dfl61 -f -R
But, phone doesnt fully boot after (stuck at Nokia logo) ?

Maybe because your command to flash the kernel isn't correct?
AFAIK, to flash a kernel it should be:
Code:
flasher -a rootfs.bin -k /path/to/zImage --flash-only=kernel

hmm, the rootfs.bin being ?
Or, if I copy the modules to the phone /lib/modules.... and do the depmod -a (after flashing complete with openmode) and then flash this kernel
flasher -F org-img.bin -k zImage --flash-only=kernel -f -R
Would that do the trick ?
I know, its a noo question, but, I reeeaaaaallyy want this NAT enabled kernel

If you don't copy the modules first and do depmod before you flash you will likely get the boot issue described. It happened to me when I first started, which is how I discovered that.

The kernel should work as it is what I've been using for months now.

Here is my /lib/modules and kernel version.

Code:
RM696-21-3_PR_006:~# ls /lib/modules/
2.6.32.48c-dfl61-20115101  2.6.32.54btlc-dfl61
2.6.32.54-dfl61-20121301   current
RM696-21-3_PR_006:~# uname -r
2.6.32.54btlc-dfl61
With the modules in /lib/modules/2.6.32.54btlc-dfl61 do:

Code:
 depmod -a 2.6.32.54btlc-dfl61

Cool, good to know. Thanks.

I bet you don't have to do depmod because I had already done it before creating the modules archive and subsequently updloaded the tarball.

If you compile your own modules, you'll definitely have to do a depmod before rebooting.

Shouldn't you point the current symlink also to the correct directory?
At least in fremantle it was definitely needed.

Certainly won't hurt. I'm not sure what processes actually read that symlink vs doing the equivalent of evaluating 'uname -r' at runtime.

Anybody know?
