A few more First-Day issues

I have been able to get access to the GTA01-VB4 a little more, but I am 
still puzzled about a few things, which I intend to figure out 
eventually, but if someone can come up with some pointers that will 
speed it up, I'll much appreciate it :-)

Right now I have the following loaded, which seems to be the latest 
pre-build kernel and image:

./dfu-util -a 1 -R -D u-boot-gta01bv4-r12_0_2632_0.bin
./dfu-util -a 3 -R -D uImage-
./dfu-util -a 5 -R -D 

I was once able to make a connection to another phone, but no sound was 
delivered. Also, it seemed to have problems disconnecting the call, even 
if the other side had, so my action was to remove the battery to ensure 


alsactl -f /etc/alsa/gsmhandset.state restore

Didn't change anything with regard to getting sound through *).

Moving the alsa modules to the phone is mentioned, but I haven't been 
able to do that on a running system, so I am wondering if it has to be 
done by including it into a jffs2 image?

Why does access have to be through ssh? In a secure environment, we are 
a couple of guys who are very comfortable with telnet and ftp and as the 
resources are still limited, it doesn't seem out of line (please spare 
me the paranoia that I often hear when discussing this with young 
people, because I am well aware of the potential problems :-)

While experimenting with accessing the GSM device by using:

root at fic-gta01:~$ cu -l /dev/ttySAC0

I'm able to connect to the GSM device, but I am not able to quit. I only 
seem to be able to get "OK" or "ERROR" back, but it won't leave and let 
me get back to the terminal. Is this expected behavior at present, or am 
I missing something?

Then, when I will eventually be able to build a kernel, I am wondering:

is the only way to change to it, by loading it through the dfu-util, or 
is it also possible by using a more "desktop like method", like building 
a kernel, putting it in somewhere, eg. /boot, update /etc/lilo.conf, run 
lilo and then reboot?

I am hoping to eventually be able to run everything natively on the 
Neo1973, just like on a desktop. Hey, it runs 266MHz so it should have 
plenty horsepower to build its own kernel :-)


*) Attempting to see if proper sound modules are loaded I checked, but 
finding the following I'm not able to see if what should be there, is.
Is anyone able to tell me what the situation should be to get handset 
sound out of it?
