Problem was with the tftp software I was using.
Using another router with OpenWRT already installed - ip 192.168.1.11
Installed atftpd, mounted an USB drive with the firmware - formatted as FAT.
Installed kmod-usb-serial-pl2303 and picocom - to be able to access AP350 U-BOOT via an USB to serial connector.
BusyBox v1.25.1 () built-in shell (ash)

After boot, need to configure network access.
Using picocom
set network.lan.gateway='192.168.1.11'
uci commit
service network restart
Can now use WINSCP to transfer sysupgrade to /tmp
sysupgrade /tmp/openwrt-18.06.4-mpc85xx-p1020-hiveap-330-squashfs-sysupgrade.bin
Go make a hot drink and wait 
N.B. I will post the logs of this later. I have a batch of AP350 to install OpenWRT on.
