[SOLVED] -nogui documentation request

mwb1100 · Oct 30th 2021, 9:48pm

Can documentation for -nogui be added in the the user manual for jlink.exe?

The UM08001_JLink.pdf from the v7.56b package only mentions -nogui for the GDB Server and worse it makes no mention of the required argument (-nogui 1 is needed for jlink.exe). Perhaps GDB Server doesn't need the "1" argument? This led to a bit a head scratching about why jlink.exe would complain about "Missing command line parameter after command -NoGui". (why does -nogui need an argument anyway?)

Also, the release notes for commander and some forum posts indicate that -nogui is documented on the wiki (wiki.segger.com/J-Link_Commander#-NoGui), but that isn't the case. The J-Link Commander Wiki page doesn't mention -nogui at all (maybe it was removed for some reason?).

Hi,
Thank you for your inquiry.

The -NoGui command was lost when the wiki page was reworked.
We corrected the J-Link Commander documentation accordingly:
wiki.segger.com/J-Link_Commander#Batch_processing

Thank you for making this known to us.

The J-Link Commander requires parameters for all command line options for historical reasons.
In theory, there are multiple command line options that would not require a specific value to work (-AutoConnect, -ExitOnError, -NoGui).
However it was decided against changing the behavior in retrospect,
a) to stay backwards compatible and
b) to stay consistent with the current command line scheme used for the J-Link Commander.

Does this answer your questions?

Best regards,
Fabian

Thanks for updating the docs - I did manage to work things out, but was left confused for a bit.

And thanks for explaining the (seemingly unnecessary) argument to -nogui.

Hi,
Good to hear that you were able to figure it out even while the documentation was lacking.

We will consider this thread as closed now.

Best regards,
Fabian
