When I call the function "CallFunction" from the main I add the pointer NANDElecSignature which points on location 0x10004010. In the CallFunc the received value for the pointer is 0x10004000 and the values are stored to wrong locations. This problem only exists with char pointer not with short or int pointers. Does anybody know this problem? I'm working with Keil MDK-ARM4.21 and the ULink debugger and the LPC1114/302.

#include "LPC11xx.h" /* LPC11xx definitions */
void CallFunc(unsigned char *hallo)
{
unsigned int gugus;
gugus = 0;
hallo[0] =gugus++;
hallo[1] =gugus++;
hallo[2] =gugus++;
hallo[3] =gugus++;
}

/* Main Program */
int main (void)
{
unsigned char NANDElecSignature[8];

SystemInit();
CallFunc(NANDElecSignature);
while(1)
{
}
}

Hello, I have tested your example and could not reproduce the problem.
See the attached project. If the problem still occurs could you please add some screenshots that show the wrong content of NANDElecSignature?
