I can run forte under stm32, but i don't remeber change something,
that now i couldn't run it any more
it always cause HardFault_Handler
and the line point to :
const CStringDictionary::TStringId RMT_DEV::scm_aunDINameIds[] = { g_nStringIdMGR_ID };

the corresponding assemble is

08000b68: ldr r0, [pc, #0] ; (0x8000b6c <_GLOBAL__sub_I__ZN7RMT_DEV16scm_aunDINameIdsE()+4>)

why define the array causing HardFault_Handler?

So the CPU flags fixed your problem?

I would have expected some memory or alignment issue as the const data should be put by the linker in a dedicated section (often even flash).
