Issue booting from TFTP on Meraki MR42

[nickshanks347]

The mr42.itb image transfers successfully through TFTP but the Meraki won't load it. See the following:

As you can see, when loading through TFTP (I think the bootm command), it just says "Wrong Image Format for bootm command". Please could I get some help with this?

I believe that you need to use the sysupgrade bin file at this step
