Issue integrating Dahdi on p2020 rdb board

[mohitduggal]

while buidling image using 1.7 SDK , Dahdi gets compiled and installed also.

But dahdi modules are not installed.

Dahdi_geconf gives the following error

Can't locate Getopt/Long.pm in @INC (@INC contains: /usr/sbin /usr/sbin/perl_modules /etc/perl /usr/lib/perl/site_perl/5.14.3/ /usr/lib/perl/site_perl/5.14.3 /usr/lib/perl/vendor_perl/5.14.3/ /usr/lib/perl/vendor_perl/5.14.3 /usr/lib/perl/5.14.3/ /usr/lib/perl/5.14.3 /usr/local/lib/site_perl /usr/lib/perl/5.14.3 .) at /usr/sbin/dahdi_genconf line 14.
BEGIN failed--compilation aborted at /usr/sbin/dahdi_genconf line 14.

Even though perl modules are available .

in case i try to compile and build dahdi on board itself , it sys different kernel versions dahdi modules are built with 3.12. but uname

dahdi modules coming installed is of kernel version 3.12 , but uname -a  give kernel version 3.8

Tried rebuilding kernel with bitbake and even uImage is also created with kernel 3.12 but when booting same old kernel is being showed.

please help to resolve asap.

It looks like that you load different version of the kernel.

Test your board if kernel, .dtb and RAM disk are loaded using TFTP.

Send please message dump for your loading.

Have a great day,

I got the correct linux version for SDK 1.7 i.e. 3.12......

But dahdi modules are not loading and following error is coming.

Some how finally there is missing kernel-module-crc-ccitt module. Could someone help in loading this module in the kernel of SDk 1.7.

Thanks in advance.........................
