#189917 - modified the board
Responding to: Andy Neil's previous message
Since the mini 10 pin jtag header is hard to find in here I installed a normal 20 pin JTAG socket and connected it to the board, used the following pins:
RESET, SWDIO SWCLK , 3.3vdc, GND and SWO pin if you need trace.
I put pullup resistors on PINs 3, 4 of the LPC800, the other pins have pullup resistors already.
I removed the resistor powering blue LED connected to SWDIO pin.
Download the SWM utility from LPCware.
reconfigure the pins under system to use SWDIO, SWCLK and generate code.
start a new project in keil or whatever software you are using, add the code generated from SWM software to top of your code.
Compile and generate hex file.
use Flashmagic to program your hex file to the chip using the header provided using usb to serial converter.
SWD should be available now.
