dropbear ssh with key instead of password?

SpiderKenny

I'm using ssh-copy-id to copy my key to an OmegaS2+ so I can log in without a password from a known host.
It claims to copy the key successfully, but subsequent logins still require password.

kenny@totescore ~ % ssh-copy-id -oHostKeyAlgorithms=+ssh-rsa root@192.168.1.32
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/kenny/.ssh/id_ecdsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.1.32's password: 

Number of key(s) added:        1

Now try logging into the machine, with:   "ssh -o 'HostKeyAlgorithms=+ssh-rsa' 'root@192.168.1.32'"
and check to make sure that only the key(s) you wanted were added.

Is it even possible to do this with Omega/dropbear?

@SpiderKenny You can use sshpass, here's my rough notes on how to use it to deploy firmware using scp and ssh with sshpass:

// using sshpass to deploy new firmware
ssh-keygen -f "/home/chris/.ssh/known_hosts" -R "fe80::42a3:6bff:fec3:cb5b%enp0s31f6"
sshpass -ponioneer scp -6 -o StrictHostKeyChecking=no ~/source/bin/targets/ramips/mt76x8/openwrt-ramips-mt76x8-omega2p-squashfs-sysupgrade.bin root@[fe80::42a3:6bff:fec3:cb5b%enp0s31f6]:/tmp
sshpass -ponioneer ssh -6 -o StrictHostKeyChecking=no root@fe80::42a3:6bff:fec3:cb5b%enp0s31f6 sysupgrade -n /tmp/openwrt-ramips-mt76x8-omega2p-squashfs-sysupgrade.bin
