IS2083 Getting Started

2-wire JTAG connection
J-link uses the Microchip 2-wire JTAG protocol to communicate with the IS208x MCU. This protocol specifies 5 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:
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.
- Download the J-Link package: Download
- Start JLink.exe
Debugging with Keil PK51 tools
Video
The following shows a short video that demonstrates debugging with J-Link under Keil PK51 tools.
Setup
- Download and install Keil PK51 tools V9.59 Download
- Download the J-Link package: Download
- Go to Keil installation directory
- Make sure uVision is NOT started before continuing.
- Open TOOLS.INI in text editor and add the following line:
TDRV10=BIN\JLinkBT5511.dll ("J-Link / J-Trace BT5511 Driver")
- Navigate to BIN\
- Copy the following files from the J-Link package to this directory:
- JLinkBT5511.dll
- JLinkARM.dll
Connect to J-Link
- Connect a J-Link BASE / PLUS to the PC (HW V10, see label on the back side)
- Wait until the green LED becomes steady and stops blinking
- Download the uVision test project: Download
- Open the uVision test project
- 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 2-wire JTAG)
- Rebuild your application (Project -> Rebuild all target files)
- Start a debug session by clicking the <PiC> symbol (Ctrl + F5)
- 2-wire JTAG is the default selection for a J-Link BT5511 project
- You will be asked if you want to update the firmware of the connected J-Link. Select YES.
- Happy debugging!
