I have a E320 that I wanted to update to UHD 4.0. I am currently at 3.15. I downloaded the mender artifact and image from files.ettus.com. I first tried to mend it. I scp'd it and attempted it. The following is the result from that. root@ni-e320-31DCD15:~# mender -rootfs /home/root/usrp_e320_fs.mender INFO[0000] Configuration file does not exist: /var/lib/mender/mender.conf module=config INFO[0000] Loaded configuration file: /etc/mender/mender.conf module=config INFO[0000] Mender running on partition: /dev/mmcblk0p3 module=main INFO[0000] Start updating from local image file: [/home/root/usrp_e320_fs.mender] module=rootfs Installing update from the artifact of size 89829376 INFO[0000] no public key was provided for authenticating the artifact module=installer ERRO[0000] Installation failed: installer: failed to read and install update: will not install artifact with state-scripts when installing from cmd-line.

Use -f to override module=main root@ni-e320-31DCD15:~# During this process, during the scp I noticed that it complained about the disk being full. I am using a 16 GB sd card (actually the one that came with it) and there is nothing extra on it other than the standard UHD 3.15 etc. Thinking that might be an issue I decided to try popping the cover and building a new 16 GB card from scratch using the image I downloaded.

Then it went into emergency mode. Does UHD 4.0 require a bigger disk? Thanks Jeff Long

Hi Jeff, I don't have an E320, but I did not experience any space issue using 16GB cards with either N310 or N321. BTW, I used bmaptool for the writing which is super fast compared to the other methods.
