Other Parts Discussed in Thread: CC2650

I am designing a CC2650 based sensor board .I have used the 5 pin QFN32 package IC and followed the differential circuit as per TI reference design.I am having CC2650 launch pad with me .Would i be able to program my board using the launchpad ?If so please tell me what are the pins should i be used for programming.

You can refer to connection in schematic of CC2650 LaunchPad as the followings.

Thanks YiKai Chen for the reply.I suppose the schematic you mentioned is for the JTAG debugging interface.Could you tell what are the programming interface used by the XDS110 programmer in the launchpad(UART0 or the SPI0 interface).From the launch pad schematic what we can make out is that the communication interface between XDS110 and the CC2650 are the

UART RX
UART TX
JTAG-TDO
JTAG-TDI
JTAG-TMSC
JTAG-TCKC
RESET

So as per the CC2650 reference manual UART0 must be the interface used by the XDS110 for sending out the flash commands.Is my understanding it correct ?

Thanks

I think UART TX/RX are not necessary. Only the following pins are mandatory. By the way, you also have to connect ground.

JTAG-TDO
JTAG-TDI
JTAG-TMSC
JTAG-TCKC
RESET

Thanks for the reply .So using 10 pin Jtag connector is the only interface required for programming my board.
JTAG-TDO
JTAG-TDI
JTAG-TMSC
JTAG-TCKC
RESET
GROUND
Is that you mean ?

Thanks

Thanks a lot YiKai Chen .one last query .Is the debugger on devpack and launchpad have the same XDS110.What I need to know is that can I use the JTAG pins of any of these?

Yes, they are the same one.
