Hi,
it has been a while since I have been deep,deep down in the rabbit hole
of Cortex Assembly, so please forgive me if I am overlooking something...
I have an application for Raspberry Pico (target embedded) and it fails
during initialization as soon as I add a unit that includes an object
and I reference the object in my code...
In that case fpc_initialize (for rtti?) is called and I cannot find
source code for fpc_initialize
In the debugger I see that R0 is $1000177E and R1 is $28 This is in the
flash area, so far, so good but $1000177E is obviously not word
alligned, it is halfword aligned so this then triggers _HardFault_Handler.
10001778 4648 ldr r0, [pc, #280] ;
(0x10001894 <fpc_initialize+316>)
1000177A 4058 ldr r0, [r0, r1] ; Crash
Boom Bang !!!!!
Looking at the map file the address is within fpc_initialize, but as I
cannot find the proper source I am a bit lost...
.text.n_fpc_initialize
0x0000000010001758 0x144
/Users/tgdrimi9/fpcupdeluxe/fpc/units/arm-embedded/armv6m/eabi/rtl/system.o
0x0000000010001758 fpc_initialize
0x0000000010001758 FPC_INITIALIZE
.text.n_fpc_finalize
0x000000001000189c 0x164
/Users/tgdrimi9/fpcupdeluxe/fpc/units/arm-embedded/armv6m/eabi/rtl/system.o
Any help appreciated,
Michael
