Figure 5.2-53 Program Data to Target Chip with SPI Interface 

 

More Features of Nu-Link2-Pro Firmware

 

Nu-Link2-Pro also provides different interface to program user code to target chip. These various feature 
and programming interface correspond to different firmware bin file. User can switch the roles that Nu-
Link2-Pro play by re-programming Nu-Link2-Pro to another .bin file. 

The brief description of Nu-Link2-Pro firmware as follows: 

1.  NuLink2_DAPLink.bin 

NuLink2_DAPLink.bin is the firmware supported ARM Mbed DAPLink and PyOCD for programming 
and debugging. 

2.  NuLink2_ISPLink2.bin 

NuLink2_ISPLink2.bin

 is the Nu-Link2-Pro firmware that can use offline mode to program code with 

bridge interfaces. User puts the programming data to Nu-Link2-Pro first and then programs data to 
target chip with bridge interface. 

3.  NuLink2_Bus_Monitor.bin 

NuLink2_Bus_Monitor.bin

  is  the  Nu-Link2-Pro  firmware  can  monitor  the  bus  data  of 

NuLink2_ISP_Bridge between two connected devices. 

 

The Nu-Link2-Pro also provides a method to update firmware by USB mass storage. Please follow the 
steps below: 

(1)  Hold  offline  button  of  Nu-Link2-Pro  shown  in  in  Figure  2.3-1,  plug  in  USB  cable  and  release  the 

button. 

(2)  A "Nu-Link2" disk will show as Figure 5.2-54. (If you see disk name is "NuMicro MCU", it will upgrade 

DUT firmware instead of Nu-Link2-Pro itself)
