To analyse: gdb docker then (gdb) disassemble $pc once it stops on the crash. I'd like to see if patch 2 was not applied or if something else causes this.

What's strange is that my environment is not using the meta-golang layer (If I remove the folder he doesn't throw an Error while building the image) Did you change any dependencies in the docker recipe e.g golang-cross instead of go-cross? The disassembly in gdb looks like this: (gdb) run Starting program: /usr/bin/docker [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/libthread_db.so.1". Program received signal SIGILL, Illegal instruction. 0x08080871 in runtime.check () (gdb) disassemble $pc Dump of assembler code for function runtime.check: 0x08080850 <+0>: mov %gs:0x0,%ecx 0x08080857 <+7>: mov -0x4(%ecx),%ecx 0x0808085d <+13>: cmp 0x8(%ecx),%esp 0x08080860 <+16>: jbe 0x8080d90 <runtime.check+1344> 0x08080866 <+22>: sub $0x44,%esp 0x08080869 <+25>: movl $0x0,0x28(%esp) => 0x08080871 <+33>: xorps %xmm0,%xmm0 0x08080874 <+36>: movss %xmm0,0x24(%esp) 0x0808087a <+42>: movss %xmm0,0x20(%esp) 0x08080880 <+48>: xorps %xmm0,%xmm0 0x08080883 <+51>: movsd %xmm0,0x34(%esp) 0x08080889 <+57>: movsd %xmm0,0x2c(%esp) 0x0808088f <+63>: movl $0x0,0x40(%esp) 0x08080897 <+71>: xor %ebx,%ebx 0x08080899 <+73>: mov %bl,0x1c(%esp) 0x0808089d <+77>: mov %bl,0x1d(%esp) 0x080808a1 <+81>: mov %bl,0x1e(%esp) 0x080808a5 <+85>: mov %bl,0x1f(%esp) 0x080808a9 <+89>: xor %ebx,%ebx 0x080808ab <+91>: mov %bl,0x15(%esp) 0x080808af <+95>: xor %ebx,%ebx 0x080808b1 <+97>: mov %bl,0x16(%esp) 0x080808b5 <+101>: mov %bl,0x17(%esp) 0x080808b9 <+105>: movl $0x4b57ce31,(%esp) 0x080808c0 <+112>: movl $0xb3a,0x4(%esp) 0x080808c8 <+120>: movl $0x3b9aca00,0x8(%esp) 0x080808d0 <+128>: lea 0x28(%esp),%ebx 0x080808d4 <+132>: mov %ebx,0xc(%esp) 0x080808d8 <+136>: call 0x8081300 <runtime.timediv> 0x080808dd <+141>: mov 0x10(%esp),%ebx 0x080808e1 <+145>: cmp $0x3039,%ebx 0x080808e7 <+151>: jne 0x8080d76 <runtime.check+1318> 0x080808ed <+157>: mov 0x28(%esp),%ebx 0x080808f1 <+161>: cmp $0xd431,%ebx 0x080808f7 <+167>: jne 0x8080d76 <runtime.check+1318> 0x080808fd <+173>: movl $0x0,0x18(%esp) 0x08080905 <+181>: movl $0x1,0x18(%esp) 0x0808090d <+189>: lea 0x18(%esp),%ebx 0x08080911 <+193>: mov %ebx,(%esp) 0x08080914 <+196>: movl $0x1,0x4(%esp) 0x0808091c <+204>: movl $0x2,0x8(%esp) I will try some different settings but if nothing helps I guess will have to kindly ask you to send me your image EDIT: Before stepping into the function where he crashes I get following message Single stepping until exit from function runtime.rt0_go, which has no line number information. x_cgo_init (g=0x8a98d60 <runtime.g0>, setg=0x809c2b0 <setg_gcc>) at /usr/lib/i586-poky-linux/go/src/runtime/cgo/gcc_linux_386.c:21 21 /usr/lib/i586-poky-linux/go/src/runtime/cgo/gcc_linux_386.c: No such file or directory.

Jan fixed the Illegal instruction bug in his newest commit (08a9a79) to the jan/morty branch. Also set PREFERRED_VERSION_linux-yocto = "4.4%" in local.conf

sharvari06 Posts: 1 Rating: (0)	AutoGen_4914151 Thank you very much, I was able to build the example image successfully! It seems as if docker is not supported on the intel quark x1020 though... When starting docker he says "docker requires a CPU with MMX support" But its cool that I have the latest version of the image running on the IOT now so thank you! Hello AutoGen, I am also getting same error "docker requires a CPU with MMX support". Did you get any solution for this. If yes please share it with me. Thanks in advance!!!

To fix the issue with the MMX support jan commited some changes to his branch which are not on Github anymore. I will attach the patches here for you.
