Important note
If you are using the Equinox
‘ARM ISP Cable’
to program an NXP LPC2xxx microcontroller, please
check that the resistor R6 is removed from the circuit board. This resistor is connected to a 47k ohm
pull-up to Vcc and will pull the
RTCK
pin HIGH preventing the NXP LPC2xxx device from entering
‘Debug Mode’
using the
‘JTAG Interface’
.
1.5 Getting Started
Once you have the installed into the programmer and connected to your Target System, then you are
ready to program an ARM device.
Instructions:
•
Check that you have selected the correct position for the
‘Power Supply – Selection
Jumper’
– see section 1.3
•
To be on the safe side, measure the voltage on pin 1 of the 20-way IDC connector. If the
programmer is powering the Target System, then this voltage should 3.3V.
•
If you are using the Equinox
‘ARM ISP Cable’
to program an NXP LPC2xxx microcontroller,
please check that the resistor R6 is removed from the circuit board.
•
Connect the
‘ARM Programming Cable’
to the 20-way IDC connector on your ARM Target
System
•
Power up the programmer first
this makes sure that the programmer Line Drivers are
powered BEFORE you power up the Target Board.
•
Power up the Target Board
•
Check that the programmer and Target Board power up OK.
1.6 ARM 20-way JTAG Debug Header
The pin-out of the 20-way IDC connector end of the cable is shown in the diagram below.
ARM JTAG Debug Header
The connector is a 20-pin bump-polarised IDC
connector with 0.1” pin spacing.
Pin 1 is the top right pin as shown in the diagram
opposite.
