1. ULINK2 Emulator
ULINK2 is the latest emulator from ARM designed for use with RealView MDK. It is an upgraded version of the ULINK emulator. ULINK2 not only has all the features of the ULINK emulator but also adds support for Serial Wire Debug (SWD), return clock support, and real-time agents. Development engineers can easily perform on-chip debugging (using on-chip JTAG, SWD, and OCDS) and Flash programming on target hardware by combining the RealView MDK debugger with ULINK2.
New Features of ULINK2
Standard Windows USB driver supports plug-and-play for ULINK2
Supports Serial Debugging based on ARM Cortex-M0,3,4
Supports memory read/write, terminal emulation, and serial debug output during program execution
Supports 10-pin connection cable (also supports 20-pin connection cable)
Main Functions of ULINK2:
USB communication interface for high-speed downloading of user code
View storage areas/registers
Fast single-step program execution
Multiple program breakpoints
On-chip Flash programming

2. Installation and Usage of ULINK
1. Please ensure that the ULINK driver is correctly installed; otherwise, the ULINK emulator cannot be used.
2. Project Setup
Open a project file as shown below
Click the project settings icon as shown
Open the project settings page, select chip model: LPC2103
Set the Debug selection card as follows: select hardware emulation on the right and choose Ulink Arm Debug as the emulator
Open settings and set as follows:
Set the Utilities tab
In Settings, first set the download option, then click Add to add the programming algorithm
The internal flash of the LPC2103 chip is 32K, so select the following option
Then click OK to complete the setup
3. Start Debugging
Now you can start debugging by clicking the Debug shortcut icon
Enter the emulation interface as shown below
We can see the emulation toolbar
We can see that the program running progress is just an arrow
Thus, the ULINK and ARM7 core board are successfully connected, and you can now perform single-step, full-speed running, and other debugging.
