Typical applications
This feature is useful to reduce the power consumption of the CPU when no debug
session is active.
Syntax
SetDbgPowerDownOnClose = <value>
Example
SetDbgPowerDownOnClose = 1 // Enables debug power-down on close.
SetDbgPowerDownOnClose = 0 // Disables debug power-down on close.
5.10.1.16SetSysPowerDownOnIdle
When using this command, the target CPU is powered-down when no transmission
between J-Link and the target CPU was performed for a specific time. When the next
command is given, the CPU is powered-up.
Note:
This command works only for Cortex-M3 devices.
Typical applications
This feature is useful to reduce the power consumption of the CPU.
Syntax
SetSysPowerDownOnIdle = <value>
Note:
A 0 for <value> disables the power-down on idle functionality.
Example
SetSysPowerDownOnIdle = 10; // The target CPU is powered-down when there is no
10ms
5.10.1.17SupplyPower
This command activates power supply over pin 19 of the JTAG connector. The KS
(Kickstart) versions of J-Link have the V5 supply over pin 19 activated by default.
Typical applications
This feature is useful for some eval boards that can be powered over the JTAG con-
nector.
Syntax
SupplyPower = 0 | 1
Example
SupplyPower = 1
5.10.1.18SupplyPowerDefault
This command activates power supply over pin 19 of the JTAG connector perma-
nently. The KS (Kickstart) versions of J-Link have the V5 supply over pin 19 activated
by default.
Typical applications
This feature is useful for some eval boards that can be powered over the JTAG con-
nector.
Syntax
SupplyPowerDefault = 0 | 1
