The IS208x series is an 8051 based device from Microchip that is designed for low power Bluetooth applications.

J-Link support

J-Link supports the Microchip IS208x 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 IS208x MCU. This protocol specifies the following pins which are all mandatory to connect:

  • RESET (mandatory to enable 2-wire JTAG protocol on the IS208x)
  • VTref (used as reference voltage by J-Link to adapt to different CPU operating voltages)
  • GND
  • bi-directional data pin
  • clock (provided by J-Link)

On the BM8x EVB connector J301 is used to connect J-Link to the IS208x 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 IS208x device.

Supported IDEs and debuggers

Currently, the IS208x 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

Setup

  • 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 IS208x Keil package: File:JLink IS208x Keil Package.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\JLinkBT5511.dll ("J-Link / J-Trace BT5511 Driver")

  • Copy the following files from the J-Link package to this directory:
    • JLinkBT5511.dll
    • JLinkARM.dll

Debug session

  • 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:

  • 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!
