Thanks to Segger Support I found the right info pages. It is possible to do with the JLink.exe an individual pinreset with the "exec SetResetPulseLen = 100" command.

Segger J-Link Command:
https://wiki.segger.com/J-Link_Commander
https://wiki.segger.com/J-Link_Command_Strings

CommandLine to execute:

JLink.exe -device nrf52840_xxAA -if SWD -speed 4000 -autoconnect 1 -CommanderScript ".\JLinkCommands.jlink"

JLinkCommands File:

exec SetResetPulseLen = 100
RSetType 2
r
q

Hi,

We do, but AFAIK the Segger J-link does not execute a pin reset but rather a soft reset through the use of CTRL-AP. The Segger Commander has a commando for executing a reset with delay but note that this is most probably a soft reset, not a pin reset.

Hi,

So you are not using the Segger JLink lib in the background (there it should theoretically be possible to define a reset time)? So if you know any other possibility to control the reset pin from a SeggerDebugger which is callable in a batch File line, that would also help me a lot.

Hi,

Unfortunately, this is not possible. The reset will be executed once the RESET pin is asserted, and the time it takes for a RESET operation to complete is not configurable. Could you elaborate a bit more on your reset time requirement? Maybe there is an alternative solution.
