Are the older ones really armhf? Even for the DS-212 I doubt it. Can you please post the output of cat /proc/cpuinfo Another reason might be the use of kernel based synchronization primitives (e.g. kuser_cmpxchg), those appeared years ago in the kernel, I gues around 2.6.20. You can test this by removing the defines SYSTEM_HAS_KUSER_... in fpc/rtl/arm/armdefines.inc and recompile fpc. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
