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?

Great thank you for the answer, I did but the move of the file says that the file is too large for the destination. Plus the board stays as storage only for a few seconds then disappears. Is my board bricked?
