When using software development tools above, you may need an USB adapter. We introduce you a new feature-rich Nu-Link2-Pro adapter here.
An overview picture of software tools, adapter and targets
All Nu-Link2-Pro firmware binary files can be found here
User can re-program Nu-Link2-Pro to another .bin file by the following instructions (Windows OS)
- Press the button on Nu-Link2-Pro and plug in USB cable.
- A "Nu-Link2-Pro" disk will show. (If you see disk name is "NuMicro MCU", it will upgrade target device firmware instead of Nu-Link2-Pro itself)
- Drag and drop Nu-Link2-Pro firmware .bin file into the disk.
- Re-plug the USB cable and it's done.
warning: The meaning of options for v3.09.7380 is different from v3.05.7174r ~ v3.08.7313. This document goes with the latest version (v3.09.7380), if you want to check old setting (v3.05.7174r ~ v3.08.7313), please see the old link.
- When you upgrade the NuLink2FW.bin greater than or equal to version v3.09.7380, you will see some options in NU_CFG.TXT.
- Open NU_CFG.TXT file in pop-up "NuMicro MCU" disk
- For Nu-Link2-Pro, you will see POWER-MODE, BRIDGE-MODE options, you need re-plug in USB cable to effect the setting.
-
Set POWER-MODE for SWD output voltage level (mainly for CMSIS-DAP interface use)
-
Set BRIDGE-MODE=0, this is default setting. It has a WebUSB interface conform CMSIS-DAP protocol, and you can connect KEIL Studio via this interface. Note that CMSIS-DAP will be disable in other BRIDGE-MODE (Limited USB endpoints).
-
Set BRIDGE-MODE=1, the pass-through bridge function of Nu-Link2-Pro will be enabled (The word Nu-Link2-Bridge will be used to represent the pass-through bridge application on Nu-Link2-Pro adapter). Nu-Link2-Bridge pass-through the data between VCOM port and I2C/SPI/RS485/CAN interfaces. (You will see a "Nu-Link2-Bridge Virtual Com Port" in device manager.)
-
Set BRIDGE-MODE=2, an USB HID interface supports ISPTool will be enabled. This USB HID interface doesn't pass through data, it communicates with ISPTool via HID_ISP, and offers I2C/SPI/RS485/CAN interfaces for ISPTool.
- If you use Nu-Link2-ME, it doesn't support BRIDGE functions, you will only see CMSIS-DAP option.
- Set CMSIS-DAP=1, this is default setting. It has a WebUSB interface conform CMSIS-DAP protocol, and you can connect KEIL Studio via this interface.
- Set CMSIS-DAP=0, it will disable CMSIS-DAP and enable Nu-Link2 "USB BULK_ICE" interface (it's faster than "USB HID_ICE").
- Proprietary code
- Support NuMicro 8051, offline programming, user code read-out protection, unlimited flash break points, NuMicro chips specific features (config0/config1 dataflash setting, KPROM, etc.)
- USB interfaces: MSC/VCOM/HID_ICE(proprietary commands) or CMSIS-DAPv2 WinUSB + WebUSB CMSIS-DAP/VCOM_Nu-Link2-Bridge or HID_ISP (defined by BRIDGE-MODE of NU_CFG.TXT)
- Open source: DAPLink on Nu-Link2-Pro
- Support many third party IDE
- USB interfaces: MSC/CDC/CMSIS-DAPv2 WinUSB/WebUSB CMSIS-DAP
