On-board Debugger

The on-board debugger [1] supports

Serial Wire Debug

Serial Wire Viewer [2]

Full Duplex UART communication via a USB Virtual COM
[1] Attention: Newer firmware versions of the on-board debugger require the latest J-Link driver (V4.62 or
higher) and a Serial Port Driver (CDC driver) installed on your computer. Please check "Install J-Link Serial
Port Driver" when installing the latest J-Link driver (see Figure 11)
Figure 11 Installation of Serial Port Driver
[2] If Serial Wire Viewer is used, the User LED cannot freely be programmed and starts flickering, because the
Serial Wire Viewer function is overlaid with the GPIO function connected to the User LED.
The on-board debugger can be accessed through the Debug USB connector shown in Figure 12. The Debug
LED V502 shows the status during debugging.
Figure 12 On-board Debugger
When using an external debugger connected to the 10pin/20pin Cortex Debug Connector, the on-board
debugger is switched off.
When using the USB virtual COM port function of the on-board debugger the on-board CAN interface is
disabled through the switches U301 and U303.
