IS2083 Getting Started
The IS2083 series is an 8051 based device from Microchip that is designed for low power Bluetooth applications.
J-Link supports the Microchip IS2083 series devices. For an overview which min. hardware of J-Link is required for support, please refer to the feature overview.
Hardware connection to BM83 EVB
J-Link uses the Microchip 2-wire JTAG protocol to communicate with the IS2083 MCU. This protocol specifies the following pins which are all mandatory to connect:
- RESET (mandatory to enable 2-wire JTAG protocol on the IS2083)
- VTref (used as reference voltage by J-Link to adapt to different CPU operating voltages)
- bi-directional data pin
- clock (provided by J-Link)
On the BM8x EVB connector J301 is used to connect J-Link to the IS2083 MCU.
We recommend to use the J-Link Microchip 2-Wire JTAG TDI Adapter to connect J-Link to J301.
|J301 pin||J-Link pin|
|1||15 (RESET, blue)|
|2||1 (VTref, red)|
|3||4 (GND, black)|
|4||5 (TDI, green)|
|5||9 (TCK, yellow)|
Verifying connection with J-Link Commander
J-Link Commander (JLink.exe from the J-Link package) can be used to verify the connection between J-Link and the IS2083 device.
- Download the J-Link IS2083 package: Download
- Start J-Link Commander (JLink.exe)
Supported IDEs and debuggers
Currently, the IS2083 is only supported in J-Link Commander and Keil uVision for PK51. Other utilities (J-Flash, ...) / IDEs etc. do not support this device series.
Debugging with Keil C51 tools
- Download and install Keil C51/PK51 tools V9.59 or later: Download
- Download the latest J-Link software from our website (to make sure that the USB drivers etc. are installed): Download
- Download the J-Link IS2083 Keil package: JLinkIS2083_6.44.4.zip
- Make sure uVision is NOT started before continuing
- Go to Keil installation directory
- Open TOOLS.INI in text editor and add the following line (if TDRV10 already exists, use the next available number/entry):
TDRV10=BIN\JLinkIS2083.dll ("J-Link / J-Trace IS2083 Driver")
- Navigate to BIN\
- Copy the following files from the J-Link package to this directory:
- Connect to the PC
- Wait until the green LED of J-Link becomes steady and stops blinking
- Download the Microchip BM83 SDK application sample project from Microchip
- Make sure that you followed the initial preparation steps for the BM83x EVB from Microchip (flashing of initial image + DSP config etc.)
- Open project in uVision
- Go to the project options
- Verify that your options look like as follows:
- 'Device' tab:
- 'Debug' tab:
- Click on 'Settings'
- 'Settings' dialog
- Connect your target HW to J-Link via J-Link Microchip 2-wire JTAG TDI adapter
- Rebuild the application (Project -> Rebuild all target files)
- Start a debug session by clicking the "debug" symbol (Ctrl + F5)1
- Happy debugging!
