Hello, I am attempting to evaluate Xenomai and am running into an
illegal instruction when I try to run trivial-periodic. I am running
Xenomai 2.5.5.2 with kernel 2.6.33.5-x3 on a Beagleboard. Kernel and
Xenomai were cross compiled with CodeSourcery 4.4.1. Upon boot I can
see /proc/xenomai/*. Attempting to run trivial-periodic results in
the following output:
Xenomai or CONFIG_XENO_OPT_PERVASIVE disabled.
(modprobe xeno_nucleus?)
Note that CONFIG_XENO_OPT_PERVASIVE is in fact enabled, and nucleus is
built into the kernel. Running in GDB, trivial-periodic receives
SIGILL (illegal instruction) and exits. I get the following
backtrace:
#0 0x40022498 in xeno_bind_skin_opt () from /usr/xenomai/lib/libxenomai.so.0
#1 0x00000000 in ?? ()
And the disassembly around the PC is:
0x4002247c <+124>: movw r0, #555 ; 0x22b
0x40022480 <+128>: mov r6, r5
0x40022484 <+132>: mov r1, r8
0x40022488 <+136>: mov r2, #1610612743 ; 0x60000007
0x4002248c <+140>: mov r3, #3
0x40022490 <+144>: mov r4, r7
0x40022494 <+148>: svc 0x009f0042
=> 0x40022498 <+152>: ldr r12, [sp, #2140] ; 0x85c
0x4002249c <+156>: cmp r12, #0
0x400224a0 <+160>: beq 0x4002246c <xeno_bind_skin_opt+108>
0x400224a4 <+164>: mov r2, r0
0x400224a8 <+168>: mvn r1, #84 ; 0x54
0x400224ac <+172>: mov r0, r11
0x400224b0 <+176>: bl 0x400220d8
0x400224b4 <+180>: cmn r0, #85 ; 0x55
The other example programs result in a SIGILL in exactly the same place.
Does anyone have any ideas or suggestions?
Thank you.
- Eric

I would say you have incompatible ABI settings for kernel-space and
user-space.

Here we definitely see an OABI syscall. So, your kernel is probably
configured for EABI.

Gilles, thank you for the prompt and helpful response. I rebuilt with
--enable-arm-eabi and everything seems to be working now.
