I have now tried checking out a clean tree from svn and building the
at91sam9260pf_defconfig after disabling most packages and adding curl.
I hacked the machine type so the kernel would boot, my board is based
off the at91sam9260ek. It does the same thing, boots perfect. Illegal
instruction with curl.
Does anyone have a know working buildroot configuration for a
I will get out the actual AT91SAM9260EK dev board tomorrow and see if
the same thing happens.
I copied the curl binaries from my old known working buildroot into my
new buildroot rootfs. These binaries function fine.
Does this mean something is wrong with gcc?
