nRF Connect 3.2.0 Programmer, SEGGER clock speed

[Omar Al Attar]

Hi,

is there a way to change the programming clock frequency of the SEGGER j-Link programmer (I'm using j-Link Lite) in nRF Connect 3.2.0 Programmer?

I did modify the define "Clockspeed=2000" to "Clockspeed=1000" in nrfjprog.ini which is located in "C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin", but there was no change, the log is always showing Segger speed 2000 kHz.

Thanks for the help

What is the use case? Why not use the nrfjprog command line tool directly with the --clockspeed parameter?

Because nRF Connect shows useful information when connecting a target, like Model, SoftDevice id and version, etc. Also the memory layout visualization is cool.

Thanks for the details, but it is not possible no.

Thanks for the info. I think, it would be nice to add this option. In our case it's needed, because we have to filter the SWDIO pin to suppress EMC events casing target resets. Generally 1MHz clock is the max. what we can use.
