You don't need the kernel source. You can convert the compiled device tree blob to the text version, edit it, and the convert it back to the binary using dtc:
# backup the original .dtb cp /boot/am335x-boneblack.dtb /boot/am335x-boneblack.dtb.orig # generate the dts from the dtb dtc -I dtb -O dts -o am335x-boneblack.dts /boot/am335x-boneblack.dtb # modify the dts with a text editor # generate the dtb from the modified dts dtc -I dts -O dtb -o am335x-boneblack.dtb am335x-boneblack.dts On Wednesday, November 20, 2013 6:18:53 AM UTC-8, cody wrote: > If you have the kernel source it is located at > arch/arm/boot/dts/am335x-bone-common.dtsi > Then you will need to recompile the am335x-boneblack.dtb > > > On Wed, Nov 20, 2013 at 4:04 AM, chai <chaitra.m...@tismotech.net<javascript:> > > wrote: > >> hi, >> can i know where I can find the am335x-bone-common.dtsi? >> it is not present in /lib/firmware so where can i find out???? >> >> -- >> For more options, visit http://beagleboard.org/discuss >> --- >> You received this message because you are subscribed to the Google Groups >> "BeagleBoard" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to beagleboard...@googlegroups.com <javascript:>. >> For more options, visit https://groups.google.com/groups/opt_out. >> > > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
