updating firmware: error 1842

[sam81]

I am trying to update my PM 5 with the latest firmware. I've installed the latest utility software on my laptop, inserted a fresh formatted USB stick, and downloaded the latest firmware onto it.

When i stick it into the back of the PM5 and switch on i get a 'usb stick error'. The error in question is error 1842.

It's only a 4gb stick and was formatted to fat.

Any ideas?

Find a USB 2.0 stick or USB 3.0 one that really works as USB 2.0 (with proper compatibilty).

Or wire the PM5 to your laptop and forget using any USB stick.
