hi there,
I'm developing a C program for an embedded device in order to use it as a pad which is able to recognize handwriting. In short, the program is supposed to extract several features of the signature and calculate a biometric hash.
Sadly the program keeps crashing as soon as I use malloc or realloc. Since I'm not able to debug the malloc function I can't really see the cause for that.
int32_t *foobar; foobar = malloc( sizeof(int32_t) ); //CRASH
I don't even know where to start looking for a solution, except for google which didn't provide the answer I was looking for, so maybe anyone here could give me a solution or a hint to fix it.
If there is some important information missing please just tell so and I will see if I can add it.
I'm working with Keil yVision:
stats for the embedded device ARM-7 32bit Architecture NXP (Philips) LPC 2368 72 MHz 512 kB on-chip Flash 58kB SRAM
That is the fundamental problem with dynamic allocation!
And it's a particular difficulty for embedded systems as you can't just put up a user dialogue saying, "out of memory"!
This is why dynamic allocation may be best avoided in embedded systems...
