good afternoon, i'm using a lpc2148 with uvision keil. Now I built my own board. When I tried to connect through jtag it was available only at 50kHz and lower frequency, but the erasing a loading seems to be correct. I use only simple tested code:
#include<stdio.h> #include<LPC214x.h>
int main(void) { IODIR1 = 0x000F0000; IODIR0 = 0x000F0000;
IOSET1 = 0x000F0000; IOSET0 = 0x000F0000; }
When I check if there is a logical one at P0.16-19 and P1.16-19. There was same signal as before. The programming was without any effect.
What could be wrong?
