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 _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
