I am experimenting problems with the build host environment. I would appreciate if someone could build the image for me, or give me some straight instructions to do that. Following this instructions gives me several errors, related to /work/isar/meta/recipes-core/isar-bootstrap/isar-bootstrap-target.bb:do_boostrap and [...]/isar-bootstrap-host.bb:do_bootstrap (sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set) I am trying to run a Simcom SIM7500/SIM7600 in my iot2050. I attach the readme provided for installing the drivers. The driver is in this link Attachment readme.txt (411 Downloads)

Then rebuilding the image using the docker method? -> its the easiest to do because you dont have to care about unmatched dependencies on your host machine... BR

When I tried to do the ./kas... with sudo, the command stop before the building process due to avoid some future problems related with that. I was not able to include a custom /build directory. Can you give me some clue? Thanks in advance

Basically your user needs to be in the docker group and the kas command must not be executed as root or with sudo. What are your errors about the /build directory? Could you share the console log? Best regards!

I did something wrong when I tried to give persmissions to my new /build directory... (maybe I did not add my user to docker group, or maybe I created with sudo the /build directory -in the root filesystem- and after I tried to change permissions on it and... crash my sudo user status... I do not remember) so now I have problems with the sudo user and I have to reinstall my OS. Thanks for the link, I will try it again and will post the results. I have to say that I have chosen this LTE pcie card because we are developing an application that should work wathever the LTE frecuencies are (Europe, America,...) and also for the 2G fallback feature. PS: I am also looking for a WiFi USB dongle (is there any usb device with the capability of external antenna proved to be working with this OS?) I will create another entry with this.
