Hi,
I am building a circuit to program an LPC2106 MC. I got this MC from an old circuit which was still working. I made these connections:
>all four Vss to ground
>both Vdd to 3.3V
>one Vcore to 1.8
>reset pulled up with 4.7k
>Xtal to 11.0592 crystal
>TX,RX to serial port using max3232
With these connections,I tried to see if the device would be detected. I even had the P0.14 held to ground. But nothing happened.Then I used the serial port and sent a few characters and i got some other characters back and this happened only when i reset it. I did all the connections to the board myself, so is there a possibility that the device is dead or does it have some kind of code security? I used LPC2000 Flash utility to check this. Please help
