thanks for your reply brandon I its hard for me to update kernel-source for my bbb. when i execute the command it always says root@beaglebone:~# opkg install kernel-headers Package kernel-headers (3.8.13-r23a.22) installed in root is up to date.
when i look inside the /lib/modules/3.8.13/build/ no source files yet available. what shall i do ..to insert a module program.. right now my beagle bone black comes with following specifications root@beaglebone:~# dmesg | head [ 0.000000] Booting Linux on physical CPU 0×0 [ 0.000000] Initializing cgroup subsys cpu [ 0.000000]* Linux version 3.8.13 (koen@rrMBP) (gcc version 4.7.3 20130205 (prerelease) (Linaro GCC 4.7-2013.02-01) ) #1 SMP Tue Jun 18 02:11:09 EDT 2013* [ 0.000000] CPU: ARMv7 Processor [413fc082] revision 2 (ARMv7), cr=50c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] Machine: Generic AM33XX (Flattened Device Tree), model: TI AM335x BeagleBone [ 0.000000] Memory policy: ECC disabled, Data cache writeback [ 0.000000] On node 0 totalpages: 130816 [ 0.000000] free_area_init_node: node 0, pgdat c0688d80, node_mem_map c06e4000 [ 0.000000] Normal zone: 1024 pages used for memmap is it necessary to update my os or i can do my module programs by simply updating codes inside.!!1 On Saturday, 8 March 2014 02:42:31 UTC+5:30, Brandon I wrote: > > dmesg will give you more details. > > This usually means you compiled the kernel modules against a different > build of the kernel.
