Hi,

I know you can disable the factory reset button by sending “AT!FWD=FACTORYRECOVERY,DISABLE” to “/dev/ttyAT”, but is there a way to do so by default, without having to send an AT command ?

I couldn’t find a way for “/mnt/userrw/sierra/.efdr” to have a default value of “0” instead of “1”.

Thank you in advance for the reply.

Best regards,  
Sami

you can write a legato application to send the AT command after power on

This is one of the solutions I was considering, but I just wanted to know if it was possible to disable it by default with parameters in a Yocto recipe for example.

Thank you for the quick reply !
