JTAG and TTL to RS232 UART for Jetson TX1

Please help me to find the JTAG Debugger and TTL to RS232 for using with Jetson TX1 evaluation kit.

Serial console is described here, and lists a compatible serial UART:

JTAG is a different story, I have one reported to be compatible, but after a couple of weeks I’m still struggling to get it to work (the setup is incredibly complicated and the only support files I’ve found seem to have missing components or steps are undocumented). If I get it working I’ll post more. FYI, the OpenOCD debuggers are generally not successful at debugging the Tegra products…even for products OpenOCD works with I think there are no 64-bit ARM CPUs included.
