Hi all I am trying to run Ubuntu with preempt rt on my beaglebone black. I've been trying this for days without much success...
I can boot my BBB into ubuntu by using "BBB-eMMC-flasher-ubuntu-13.04-2013-06-14.img" and other similar files. However, I fail to update its kernel. 1. I figured that there is kernel 3.8-rt in github. I followed the instruction in http://dev.ardupilot.com/wiki/building-the-code/building-for-beaglebone-black-on-linux/ However, my BBB won't boot. I know that the instruction is meant for debian. So, it it not applicable to Ubuntu? I've tried other beagle bone kernels in github, but I get errors while applying preempt-rt patch. 2. How do I install a new kernel? what I'm doing right now is: a) build kernel with make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- beaglebone_defconfig -j4 make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- menuconfig make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage dtbs LOADADDR=0x80008000 -j4 make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- modules -j4 make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- am335x-boneblack.dtb -j4 mkdir -p ../export/rootfs make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- INSTALL_MOD_PATH=../export/rootfs/ modules_install b) copy kernel to BBB lib/modules/my_new_kernel_modules -> rootfs/lib/modules kernel/arch/arm/boot/zImage -> rootfs/boot/uboot kernel/arch/arm/boot/dts/am335x-boneblack.dtb -> /boot/uboot Sometimes, after installing a kernel, BBB manages to boot and I see multiple kernels when I do "ls /lib/modules". However, "uname -r" tells me that I am still booting from the old kernel. Is there anyway to choose the kernel to boot? I really need some help, and any help would be greatly appreciated Regards, Steve -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
