Closed thuoeg closed 11 years ago

thuoeg commented 11 years ago

Hi, I'm to use this kernel for the a2f-actel-dev-brd platform. The kernel build sucessifully, and load using u-boot. I've build busybox 1.16.0 sucessifully and update my initramfs-list-min file with basic character devices in /dev i.e console and the necesary $slinks for the busybox including /bin/init, but I keep getting the above error.

Please help

Hi, yes, busybox has support for init and I've added "init=/bin/init" to bootargs in uboot and still I'm gettting the same error. However i think the problem is the way I'm building busybox i.e It's configuration, toolchain I'm using and the initramfs-list-min file. Though, I'm relatively confident on my setting in initramfs-list-min, I'm not sure of my configuration and toolchain. Currently, this is what I,m doing:

            Toolchain: arm-uclinuxeabi- (Sourcery G++ Lite 2011.03-46)
            Configuration: default configuration -> defconfig  but I build statically i.e no shared lib.
            Busybox version: busybox-1.20.2.

Please help. If i can get the basic initramfs-list-min .config for busybox and the toolchain you are using, that will be great.

Thanks.

Hi,

The toolchain looks like the correct one. Check the optimization options you are using. You should use -mcpu=cortex-m3 -mthumb for uclibc and busybox build.
