Asterisk on Embedded Linux

Asterisk on Embedded Linux

[Iwan Koenig]

Does anyone known how to compile Asterisk for a
powerpc-processor?
I have tryed:
./configure --target=powerpc-linux
--host=powerpc-604-linux-gnu --prefix=/opt/packages
And it gives following error:
 /root/pwlib/include/ptlib.h... configure: error:
cannot check for file existence when cross compiling

Ok! I see that it is trying to find the PWLIB-Library.
Also, i have tryed to compile the pwlib.
But it didn't work :(. For PWLIB i need the OpenLDAP,
and when i have compiled the OpenLDAP, than needs
PWLIB other packages.......
Also, have anyone ideas, how to compile Asterisk für a
powerpc-processor with another way?

Thanks!!!!

Which version of Asterisk do you want to use? I have version 1.2.X 
cross-compiled, but asterisk sources need to be patched. E.g. the
host tools ar and ranlib are hardcoded in Makefiles.
(I don't know the status for version 1.4).

Usually, a lot of open-source software isn't cross-compile friendly. 
The easiest way to actually build such stuff is to do a native build - 
yes, this will be slow, but you'll probably spend more time fixing 
makefiles and scripts (and will likely just gave up on this).

I'm not sure if our experience applies to you since we use asterisk as a 
TA instead of a PBX in our embedded gateways. We ran into a lot of 
problems when trying to cross-compile a trimmed down version of 
asterisk. Basically, we only needed the sip stack, fxs support, and some 
codecs. It was a big effort, but we are currently successfully 
cross-compiling asterisk for several platforms. We had to change 
Makefiles, source code, etc.

I would start by removing the references to PWLIB and anything I don't 
need from the makefiles and #ifdefing code that uses it until I get it 
to compile. Then start testing it and adding features as needed.

This is the command line we use to compile asterisk (just to give you 
and idea. It won't work with your sources. We don't run configure):

make CC=powerpc-uclibc-gcc CONFIG_TA=y OPTIMIZE="-mcpu=603e -Os" 
HOSTCC=gcc all

Asterisk + bristuff (for isdn support) for uclibc does crosscompile (and
run) but needs patching in several places (make files and asterisk itself).
We got the zaptel drivers to cross-compile also but it seems there are
endianess issues with the drivers we now try to iron out.

The main "difference" is that we have used OpenEmbedded as our build system
in order to get going.

Uncompressing Kernel Image ... Error: inflate() returned -3 GUNZIP ERROR - must RESET board to recover

[Henry Bausley]

I am getting the error

Uncompressing Kernel Image ... Error: inflate() returned -3
GUNZIP ERROR - must RESET board to recover
OK

when u-boot tries to uncompress the kernel.  I am using a board based upon a 
Yosemite AMCC 440EP.
I do have some boards that work.  Does anyone know what could cause this 
problem.  Bad Flash , Bad DDR ?

I would suspect a DDR problem. Please (re-)check your DDR setup and 
configuration.

BTW: This is the wrong mailinglist. You should post to the U-Boot list 
instead.

Re: Uncompressing Kernel Image ... Error: inflate() returned -3 GUNZIP ERROR - must RESET board to recover

[Nethra]

change ur bootm address it will work fine....

see the fallowing example..

Linux crashes when uncompressing the kernel
Question:
When I try to boot Linux, it crashes during uncompressing the kernel image:
=3D> bootm 100000
## Booting image at 00100000 ...
Image Name: Linux=E2=88=922.4.25
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 1003065 Bytes =3D 979.6 kB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... Error: inflate() returned =E2=88=923
GUNZIP ERROR =E2=88=92 must RESET board to recover
Answer:
Your kernel image is quite big =E2=88=92 nearly 1 MB compressed; when it ge=
ts
uncompressed it will need 2.5
... 3 MB, starting at address 0x0000. But your compressed image was stored
at 1 MB (0x100000), so
the uncompressed code will overwrite the (remaining) compressed image. The
solution is thus simple:
just use a higher address to download the compressed image into RAM. For
example, try:
=3D> bootm 400000
