Thread-topic: Floating point Exception when MMU support is ON in Petalinux

Hi,

When I configure the MMU support ON on a Petalinux distribution petalinux-v0.40-rc4 on Xilinx Microblaze, I get the following error while compiling the kernel :

make[1]: Entering directory `/home/mayuri/petalinux-v0.40-rc4/software/linux-2.6.x-petalogix'

CHK include/linux/version.h

CHK include/linux/utsrelease.h

CC scripts/mod/empty.o

make[3]: *** [scripts/mod/empty.o] Error 136

make[2]: *** [scripts/mod] Error 2

What can be the possible problem here ? Doesn’t rc4 distribution support MMU?

Thanks,
