Hi, I have a strange problem with buildroot built for an em-x270 board (an arm pxa270 based platform from compulab.co.il). All the build is performed correctly, and after some small change I have a working environment with busybox, udev, alsa, wireless tools, modutils and a kernel 2.6.23.1 (patched with some platform-dependent patch). But some program doesn't work at all, because the program receives a SIGILL (Illegal Instruction exception): for example, wget crashes after reading a remote file, udevd do not work at all, and also udhcpc crashes. I have straced udevd and wget, and it seems to crash after a certain call to syscall_nnnn where nnnn is different between the two applications. I have tried many, many different configurations, involving different version of gcc (4.0.1, 4.1.2, 4.2.1), of binutils (2.18 and 2.18.50.3, AFAIR), of uclibc (0.9.29 and 0.9.28.x) and kernel headers (2.6.23 and 2.6.22). I also have tried with different arm cpu optimizations, xscale and generic, and xscale w/ coprocessor for the uclibc (I hoped that the problem was in the different cpu for the uclibc and toolchain, but without luck). I have passed --with-cpu=xscale to binutils and gcc. None ot these configurations makes the system work. I can exclude the kernel, because it's taken from the working angstrom-linux provided by compulab, and it works well compiled with the uclibc toolchain and a standard glibc toolchain, in both cases. I attach the configurations files. Do you have any idea or suggestion ? do you need any other test or information?
Thank you in advance! best regards, ing. Federico Fuga --
