The cold-plug solution (4044) is for CMSIS-DAP adapter only.
No wonder it does not work with J-Link.

Tom,
I read your post, which I somehow missed when searching for a
solution, and pulled the latest master. Changed atsamd91.c and
cmsis_dap_usb.c to patch versions (4043 and 4044) and installed.
I got the following error:

As I understand it the fix merged into the git master is for the
DSU. Other patches are required for SAMD CPU extended reset.

Has anyone had any success with using openocd to erase ATSAMDA1 or
ATSAMC21 devices which have the security enabled?
The command:'at91samd chip-erase’ says it will erase the device
when security enabled. However when the security is set openocd
doesn’t appear to be able to run the ‘init’ command on the device
successfully.
Please see
https://sourceforge.net/p/openocd/mailman/message/35704580/
http://openocd.zylin.com/4043 is already merged in git master.
