8.1.2.1 Target board design
8.1.2.2 Pull-up/pull-down resistors
8.1.2.3 Target power supply
J-Link / J-Trace (UM08001)
* Optional to supply the target board from J-Link.
We strongly advise following the recommendations given by the chip manufacturer.
These recommendations are normally in line with the recommendations given in the
table Pinout for SWD on page 174. In case of doubt you should follow the recommen-
dations given by the semiconductor manufacturer.
A pull-up resistor is required on SWDIO on the target board. ARM recommends 100
kOhms.
In case of doubt you should follow the recommendations given by the semiconductor
manufacturer.
Pin 19 of the connector can be used to supply power to the target hardware. Supply
voltage is 5V, max. current is 300mA. The output current is monitored and protected
against overload and short-circuit.
Power can be controlled via the J-Link commander. The following commands are
available to control power:
