root@fx30s:~# fwupdate download mcu-rmfw-boot-yocto-legato_wp85.cwe
Connecting to service …
Connecting to service …

Error in download
root@fx30s:~# packet_write_wait: Connection to port 22: Broken pipe
Any ideas as to what’s going on¿

Hi Aelkhabli,

Per other post, the issue maybe because Legato version different.

Please try and capture and share the complete response to confirm:

cm info
legato version
fwupdate query
logread -f &
fwupdate download ~/mcu-rmfw-boot-yocto-legato_wp85.cwe


I had the same issue. It seems that you should use the modem firmware in the generic release 14 with Legato 16.10.3.
If you use a previous version of modem fw with Legato 16.10.3 fwupdate will not work for some reason.

Here is a combination that works:

root@device:~# cat /etc/legato/version
