Is it possible to port the following C code to rust?
__attribute__ ((section(".isr_vector")))
void (* const isr_vector_table[])(void) = {
&_stack_base,
main, // Reset
isr_nmi, // NMI
isr_hardfault, // Hard Fault
0, // CM3 Memory Management Fault
0, // CM3 Bus Fault
0, // CM3 Usage Fault
&_boot_checksum, // NXP Checksum code
0, // Reserved
0, // Reserved
0, // Reserved
isr_svcall, // SVCall
0, // Reserved for debug
0, // Reserved
isr_pendsv, // PendSV
isr_systick, // SysTick
};
here main and isr_* are rust external functions, and _stack_base is defined
as
extern void _stack_base()
and gets loaded from linker script.
Also, is it possible to make a weak symbol in rust or somehow emulate it?
Weak symbols are used in C code to provide the following functionality:
isr_* functions are stubs with default implementation (morse out id code
with led, loop forever), but if any of those requires actual code, than it
is overrides the weak "morse-blinking" function symbol.
