Other Parts Discussed in Thread: CC2650STK
This is big enough for its own thread: It appears that the latest Debug DevPack XDS110 firmware (version 2.3.0.1) fixes the CC2650STK SPI (external flash / Watch DevPack) conflict with the JTAG interface. I'm not sure if this was reported anywhere, but can anyone at TI confirm this, as it is a big improvement :)
