Debugging Tegra K1
While it might not be possible to debug the Tegra K1 SOC in Jetson TK1 using cheaper debugging hardware or OpenOCD, Christian Jann was able to debug it using a Lauterbach LA-7708 DEBUG-USB2 along with a Lauterbach LA-7843 JTAG CORTEX-A adapter (eg: search eBay for LA-7708 LA-7843). Use the TRACE32 software for ARM.

There is also a Linux version of TRACE32-PowerView.
