For this I used the wiki page: https://wiki.freebsd.org/FreeBSD/arm/Cubieboard using option confifuration "CUBIEBOARD2." everything goes well, but starting on the "truck", I get this message: > > > > > > > > > > > > > > > > vm_fault(0xc08bab80, 0, 1, 0) -> 1 > > > > Fatal kernel mode data abort: 'Translation Fault (S)' > > > > trapframe: 0xc08e5a48 > > > > FSR=00000005, FAR=00000000, spsr=a00001d3 > > > > r0 =00000000, r1 =c0547c85, r2 =00000072, r3 =00000008 > > > > r4 =c3b49f00, r5 =c3b4a080, r6 =c3b4a0b8, r7 =00000000 > > > > r8 =c056b038, r9 =c3ae1700, r10=c05d4930, r11=c08e5ab0 > > > > r12=00000000, ssp=c08e5a98, slr=c024e0f0, pc =c03d7604 > > > > > > > > [ thread pid 0 tid 100000 ] > > > > Stopped at strcmp+0x4: ldrb r3, [r0] > > > > > > > > > > > > > > > > where is the problem please ? > > > > > > > > _______________________________________________ > > > > freebsd-arm@freebsd.org mailing list > > > > http://lists.freebsd.org/mailman/listinfo/freebsd-arm > > > > To unsubscribe, send any mail to "freebsd-arm-unsubscribe@freebsd.org" > > > > > > _______________________________________________ > > > freebsd-arm@freebsd.org mailing list > > > http://lists.freebsd.org/mailman/listinfo/freebsd-arm > > > To unsubscribe, send any mail to "freebsd-arm-unsubscribe@freebsd.org" > > > > > >help
