Hi I am working on a kernel module for the beaglebone black and trying to make use of preempt rt to improve timing. I tweaked some settings in the 4.1.13-ti-rt-r36 kernel and compiled it using Robert Nelson's instructions here <https://eewiki.net/display/linuxonarm/BeagleBone+Black>. The kernel runs on the beaglebone, however I cannot seem to get the headers right to install my kernel module. I first installed the kernel directly to the sd-card using the install_kernel.sh script. This does not install the kernel headers. Installing the headers for the exact same version from the repository lets me compile my module, however not insert it:
[ 1495.737241] UARTbbMod: disagrees about version of symbol module_layout Next I installed the kernel image along with headers and firmware image as .deb files, however now I cannot compile my module as I get the following error: root@beaglebone:~/UARTbbModule# make make -C /lib/modules/4.1.13-ti-rt-r36/build M=/root/UARTbbModule modules make[1]: Entering directory `/usr/src/linux-headers-4.1.13-ti-rt-r36' ./scripts/recordmcount: 1: ./scripts/recordmcount: Syntax error: end of file unexpected make[2]: *** [/root/UARTbbModule/UARTbitbangModule.o] Error 2 make[1]: *** [_module_/root/UARTbbModule] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-4.1.13-ti-rt-r36' make: *** [all] Error 2 according to some google research this seems to be a problem when cross-compiling headers on a different system architecture (my host pc has 64-bit Linux Mint 17.3 installed). Can somebody point me in the right direction on how to get the kernel headers working alongside a self-compiled kernel? Help is greatly appreciated, thanks! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
