Installation on Ledger Nano S with firmware 1.4.1

[paweljacewicz]

Hi!

I'd like to ask whether there will be available a release compiled for the Ledger Nano S with firmware ver. 1.4.1? I tried to compile it myself but get errors that some functions have wrong number of arguments passed to them. It seems like some changes in the Ledger SDK are responsible for it.

Thanks for any info!

It should be available this Week.

@cslashm Would anything have changed related to enabling communication with the Ledger CCID interface? I'm unable to do so post-update despite having performed the setup detailed here which was working for the prior FW/OpenPGP versions.

EDIT: Turned up the debugging, and scdaemon shows:

done

I still seem to be getting ERR 100696144 Operation not supported by device – any suggestions? I'll try starting from scratch just in case now that the app is rebuilt for the latest FW (thanks btw!)

[luginbash]

me2 btw, do I really really have to re-enable SIP if am on Mac?

[dantrauner]

@luginbash yes, I'd strongly recommend keeping it on unless you have a critical use case for leaving it off and know what you're doing, as it makes it a bit harder for malicious software to establish persistence. You should only need to turn it off temporarily if you're trying to one-time modify files in /System, /usr, /bin, or /sbin.
