Re: Looking for help using MP in Windows with QT
The next thing to check is that your port does all of the appropriate micropython initializations. i.e. calls gc_init and mp_init I'm using the following to initialize: #define BYTES_IN_KB 1024 #define KB_IN_PYTHON_HEAP 32 #define PYTHON_HEAP_SIZE (KB_IN_PYTHON_HEAP * BYTES_IN_KB) ... static char *...

Re: Looking for help using MP in Windows with QT
Using extern C just satisfies the linker. You need to make sure that once you're in MicroPython land, if you call ANY C++ code that it does not throw an exception, or it will totally mess up the MicroPython exception stack. As long as MicroPython doesn't call any C++ functions which may throw an ex...

The debugger isn't working inside the C code.stijn wrote:Can't you just run this under the debugger and see what's goiing on? In particular, inspect the values of type and call in the code shown.

Re: Looking for help using MP in Windows with QT
By the way QT is both C++ and C, I just have to use:
to call the C code from QT/C++ code.
Code: Select all
#ifdef __cplusplus
extern "C" {
#endif
[...]
#ifdef __cplusplus
} // extern "C"
#endif // __cplusplus

Re: Looking for help using MP in Windows with QT
Well, I've been digging some more and the hang is definitely coming from here:
Which is inside mp_obj_t mp_call_function_n_kw(mp_obj_t fun_in, mp_uint_t n_args, mp_uint_t n_kw, const mp_obj_t *args)
Code: Select all
if (type->call != NULL)
{
return type->call(fun_in, n_args, n_kw, args);
}

Re: Looking for help using MP in Windows with QT
Just an idea, but whenever nlr_push is used in the uPy code it's result is never assigned to a variable and instead it's put directly in the if condition. Not sure if this matters, but if your nlr_push implementation is the one using setjmp and setjmp fiddles with the stack etc, it just might. So t...

Looking for help using MP in Windows with QT
First I think I should give some background. I started by using the minimal build to run on Atmel SAM MCU. I started with minimal because I was embedding micropython into my existing firmware. I should also add that I am not using the current builds of MP, my project started somewhere around April 2...

Re: Need help, mp_lexer_new_from_str_len returning null
Problem solved. My firmware is heavily optimized and that was wrecking havoc with mp. I de-optimized mp's files and it seems to be working fine now.

Re: Need help, mp_lexer_new_from_str_len returning null
Actually, I forgot to mention that the heap is NOT declared in main(). Neither is the stack. My init function, heap, stack and gc callbacks are all in a separate file. Would this cause any issues? static volatile char *stack_top; static char heap[16384] = {0xff}; void mp_initialize(void) { mp_stack_...
