Did a bit of reading in bed as I didnt know a lot about SWD connections.

Realized that Vtref is needed as its the target reference voltage. Its connected to the chip now

What instructions are you following? The ones here that I see say to use Bossac, Sam-ba, and jlink.

Still struggling with this though.

Just checked the wiring with the multimeter and can confirm it is wired as below.  Still get a connection error in Ozone.

I have the Jlink EDU Mini plugged into the computer (Ozone sees it), the Jlink connected to the PCB then I supply 3.3v to the PCB

Then I click "start debug session" - "download and restart program" this then gives an error that it cant connect.

I have currently got an EDU mini hooked up to my Da Vinci Mini in SWD mode.

I am powering the chip via a 3.3v output from a Arduino uno. (leaving printer power supply disconected)

I have downloaded Ozone from the SEGGER website but cannot read the chip, what frequency should I be selecting in the software?

At the moment it says

Device "ATSAM4E8E" selected.
Connection failed.

Any Ideas?

Thanks
