Disabling Output Format "Enter" key doesn't work

[Fryguy]

I'm not sure if this issue is an application or library issue, but when I un-click the "Enter" under Settings -> "Output Format" and do "Update Settings..." to write it to the YubiKey, it doesn't actually work. Touching the YubiKey still sends a CR at the end of the string. (This is particularly annoying for chat rooms where I might accidentally bump the key and send the random string by accident, which is why I want to disable the CR)

YubiKey Nano Firmware Version: 2.5.1 Application Version: 3.1.23 Library Version: 1.17.2 Mac OSX El Capitan 10.11.1

I'm not able to reproduce this.

Can you try this with the commandline tool ykpersonalize (downloadable from https://developers.yubico.com/yubikey-personalization/Releases/) by running: $ ykpersonalize -u -1 -oallow-update

and reporting back with what output that gives. (this will remove all updatable flags except allow-update).

I am getting this error also, and am unable to disable the CR. Is there any resolution to this?

[klali]

Sorry for missing the reply to this. You would typically get that error if the allow-update flag is not set on the current config.

Though it looks like to me like only your slot 2 is programmed? (touchlevel 2306 == 0x902, low 4-bits being 2 meaning CONFIG2_VALID is set, but not CONFIG1_VALID)

@dkunitsk hope this helps your as well, otherwise more information would be required.

I have the same question. I keep dumping text in slack and other random chat windows. The way I sit on my couch, I often knock the key. :(

How can I make it not hit enter when I hit the key?

How can I tell if my slot 2 is programmed?

[klali]

update slot 1 and remove append-cr: $ ykpersonalize -u -1 -oallow-update -o-append-cr

check if slot 2 is programmed: $ ykinfo -2
