You've saved me from a lot of head scratching. I searched in vain for the relevant pins on the breakout cause I have R277! The connector pins are labeled:
Pin R277 R 901
22 TDO BT_RXD
24 TDI BT_CTS
25 TMS BT_TXD
27 TCK BT_RTS
My tweener board also has the JTAG (TDO,TDI,etc) labeling.
JTAG and BTUART are different pins on the processor so.
Does this mean that the BTconnex brings out JTAG and the non-BT boards
bring out the BT pins?
This gives me something to play with. I'll let you know...
