recently with my application, I've loaded my companies IAP Bootloader which has shifted my program up about 64KB in the flash. I've using a LPC1758 and I'm using Red suite 4 (NXP Edition) 512K
The problem I'm having is I have a set of strings in an array, as I iterate through the array, strlen is used on all strings and passed to the UART. after hitting the 3rd string in the array, strlen returns -1. I'm not sure why it happens. When debugging, the string is displayed in the watch without problems. I've set up a if statement for the -1, and to print out the string using:
sprintf(UBuf,"Some how got %d from '%s'",i,ptr);
where
i = strlen(ptr);
and ptr is a string from the array.
In my serial console, i see:
Some how got -1 from ' '
Does the string functions fail if the pointers are too high in the memory? I can't find any useful information regarding this. When debugging, ptr = 0x318CC; and is 14 chars in length;
I'm using Redlib no-host, and I'm managing my own linker scripts
