Debugging
This section briefly describes the debugging function supported by the Nu-Link Adapter. For more
details, please refer to the related user manuals.
3.1.1
Debug Mode
The Nu-Link Adapter supports debugging for the NuMicro™ Family chips based on the SWD signal
interface. The third-party tools that support using the Nu-Link Adapter for chip debugging include Keil
RVMDK, IAR EWARM, and CooCox CoIDE. Some more functions supported in Debug mode are
described as follows.
3.1.2
Breakpoints
In Debug mode, the user can add breakpoints in the code for debugging. During the real-time
simulation of the Nu-Link Adapter, the chip simulation will be stopped at a specific breakpoint. Figure
3-1 shows the breakpoint settings in Keil RVMDK Debug mode. The red labels on lines 052 and 059
indicate the breakpoints inserted; the yellow arrow refers to the code to be executed next and shows
the register value of Program Counter (PC) (i.e. “R15(PC)=0x00000D04” in the Registers pane in
Figure 3-1).
Figure 3-1 Setting Breakpoints in Keil RVMDK Debug Mode
3.1.3
Direct Register Control Interface
The Direct Register Control Interface can be used to display the register content in a target chip and
manipulate the registers. Take Keil RVMDK Debug mode for example, invoke the Debug command
and select a register from the “function register list” (e.g. ADC, CAN, CLK, etc.) to open the Direct
Register Control Interface of the selected register, as shown in Figure 3-2.

3.1.4
Semihost
When using the Semihost function, the message of the NuMicro™ Family microcontroller can be
output through UART to the debug window by the Nu-Link Adapter. That is, the message is output
without the GPIO. Figure 3-4 shows the debug messages in the “UART #1” form, which are the
messages output by the Nu-Link Adapter.
Follow the steps below to use the Semihost.
Step 1: Modify the strings in the “retarget.c” as follows.
#define DEBUG_ENABLE_SEMIHOST
// Add this line
#if defined(DEBUG_ENABLE_SEMIHOST)
/* The static buffer is used to speed up the semihost */
static char g_buf[16];
static char g_buf_len = 0;
# if defined(__ICCARM__)
Step 2: Invoke Rebuild to rebuild a project and enter Debug mode.
Step 3: In Debug mode, invoke View → Serial Windows → UART #1, as shown in Figure 3-4.
Step 4: Press F5 to program the target chip, and the debug messages are output to the UART #1
form.

3.2.2
Offline Programming
Offline Programming means that the Nu-Link Adapter can update the firmware of the NuMicro™
Family single chip directly without accessing software programs (as shown in Figure 3-6). Offline
programming is useful for mass production since the original code or firmware file does not need to be
delivered and only the Nu-Link Adapter is needed for mass production. In addition, the Nu-Link
Adapter supports “Limited Offline Programming,” which can effectively control the authorized number
of the firmware. For details, please refer to the ICP Tool User Manual.
