Intel® Quark™ microcontroller D1000 - OpenOCD can't interrogate JTAG chain

You have locked yourself out by disabling JTAG. JTAG can be disabled via the User Configuration Enable

JTAG byte (see Intel® Quark™ microcontroller User Guide chapter 6.1.2), via the JTAG pin functions (see

Intel® Quark™ microcontroller User Guide chapter 6.5), or by stopping the CPU clock (see Intel® Quark™

microcontroller User Guide chapter 6.4). To force your way back in, press and release the reset switch

with OpenOCD running (with or without the error). Quit OpenOCD by pressing control-c then restart it.

OpenOCD is properly connected if you see :
