J-Link OB image, where can I find this image

[jean-marc]

The board is PCA10040 Dows not shows as serial port but shows as a storage when BootReset. Where is the J-LINK OB image to load?

• After it disappears, does it re-connect/appear again ? Or is it completely gone after it first disappears?

• Do you have the same behavior if the board is in bootloader mode(press the IF BOOT/RESET button whilet you turn the board off and on again)?

• What version of the PCA10040 do you have?

• What OS are you running on your computer? Windows 10 ?
