Phase 1: openocd woes

encountered some problems getting openocd + jtag interface up and running. the ftdi driver has superceeded the ft2232 but the latter at least produces a connection ... example:


using recently upgraded 0.9.0 (openocd)

***using "interface ftdi" script
at least this turns on the BILED segment i chose in "data" argument to ftdi_layout

Need to resolve this before going forward. And for now I think it best I stick to using the ftdi interface



now that I have moved and settled into a new place. attaching an updated picture of a section of the lab. parts are still in bins inside the closets
