Where to find the latest J-Link firmware OB-SAM3U128-V2-NordicSemi

[venerley]

I have erased my J-Link firmware in error! after having installed the version supporting V6.12a, however that upgrade wasn't achieved via the drag and drop process.

Where can I find the .bin file to use for a Drag & Drop update process?

You'll find all the firmware and tools for our nRF5x DKs under the the Downloads tab on the repsective product pages, here is the link to the nRF52 Product page. You can alo download the J-Link Firmware for our nRF5x DKs using this link.

@Bjørn, I think I possibly understand path that I took that has got me in this mess!

1. I installed the latest macOS J-Llink which is V6.12a
2. I purchased an nrf51 Dongle and installed nrfConnect
3. nrfConnect detected and updated the J-Link firmware in the nrf51 Dongle (PCA10031) this went to Connectivity firmer version 1.0.0
4. I connected nrfConnect to the PCA10040 (nrf52 board) and accepted its offer to upgraded the firmware in that too. I think this is when thing stopped functioning correctly.

Since then all my attempts to communicate with the PCA10040 using J-Link have failed. I have tried to modify the J-Link firmware using the Drag and Drop method, which appears successful, however them when running J-Link I get the following output repeated:
