When trying to use Segger's JLinkExe it says, that there is a new firmware for the onboard J-Link OB-SAM3U128. When I do the update, it always fails at 98% with the message:
ERROR: Communication timeout. Emulator did not re-enumerate.
ERROR: Firmware update failed.
Flashing binaries with the dialog SDK (which uses JLink with JTAG itself) works.
What could be wrong here? Were can I investigate?
