Hi,
I am using System_vsprintf() to make a new string with variable arguments list as follows:
int16_t mk_stringf(uint8_t *outbuf, const char * format, ...)
{
va_list args;
int16_t i;
va_start (args, format);
i = System_vsprintf ((char *)outbuf, format, args);
System_flush();
va_end (args);
return(i);
}
I build new string with mk_stringf function and then send it via UART_write calls.
If mk_stringf() function is called less than 3 times, it works fine without problems.
But, some functions need calling mk_stringf() heavily more than 20 times, then system crashed and hanged.
Does system heap or stack is broken if System_vsprintf() is called heavily?
Any advice will be appreciated.
