It is not possible to boot RouterOS from CF on RB532.
In case Ethernet 1 port is damaged and you do not have RouterOS, there is no ways to get RouterOS on this board.
I wil take a look at the resisters and the transformer (isolation) on ether1 and see… but if they are good then the PHY chip is prob dead and I am not going to waste my time hauling out the old surface mount kits to change it out… My eyes arrent what they used to be…
Picked it up second hand to use as a “cheap” dude probe… (Live and learn)…
