Hi Everyone, I have been attempting to port a small application from an Arduino Uno over to the Due integrated into the Udoo and I am having some difficulty solely with allocating dynamic memory blocks. On the Uno... #include <stdio.h> #include <stdlib.h> #include <string.h> unsigned int ** table = NULL; void setup() { Serial.begin(9600); table = (unsigned int **) calloc(sizeof(unsigned int *), 10); delay(5000); Serial.println("Table Allocated"); } ... works fine... the Due however, hangs and I get no output from any of the Serial.print's. I have tried using malloc instead, also I tried the C++, new/delete. In any case, an attempt to allocate a dynamic block of memory causes a hang and the Due is non-responsive until I comment out the allocation statement and reupload. I have played around with the size, assuming I may have asked for too big a block (ie was asking for 144 * 4 unsigned int's at first), but even modest sizes, 10 x 4 unsigned int's blew up. I don't, unfortunately have an actual Arduino Due laying about to test the code. So I am at a loss to explain this. Am I missing something... is there some architectural issue with Due's and calloc/malloc or the avbr-libc???
Instead of using Malloc/New, if I understand what you're doing, why not just set up an array? unsigned int table [10]; That will set up an array that will hold 10 unsigned ints... Which seems to be exactly what you're wanting to do...
