PCA10040 jlink disconnected while in use

[hslee]

We were doing various tests using PCA10040. Then suddenly I can not connect to the PCA10040 board. In the boot loader mode of PCA10040 board, connection is made. What is the problem? How is it possible to recover to its original state?

ok.. in bootloader mode. JLink firmware reload...

May I ask if you have any idea of what might have caused this? What were you doing at the time? We are trying to figure out why this seems to happen once in awhile.

And what version of the PCA10040 do you have?
