CC2640R2F: Hardware necessary for debugging

Tyler Kulcsar

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2640, CC2650

I am looking to use the CC2640R2F MCU in my product, and use the CC2650 launch pad as a debugging tool for this chip. When using the CC2640R2 Launch Pad we are removing the jumpers on the board and connecting directly to the 10 pin connector in order to bypass the TM4C129 chip. My question is when we are designing the CC2640 chip and peripherals on our final product, which of the hardware components are necessary to include? The schematic for the Launch XL CC2640R2 attached as we plan to use that as reference. Thank you for any help.0647.LAUNCHXL-CC2640R2_1_0_0_Schematics.pdf

Hi,

You can use the reference design as it is.

Please see this HW guide https://www.ti.com/lit/an/swra640e/swra640e.pdf

Hi,

The relevant connections are JTAG_TMS, JTAG_TCK, nRESET, GND. Also you need to power your custom board. You can program your custom board as you have described above, but it also requires the cable. If you lost the cable or damage it you need to buy another online. Cheaper option is to connect jumper wires from P4, example connection below.

Hi Tyler,

Were you able to resolve this issue?

Hi FI,

I have not yet been able to sort this out. If you look at the Launch XL CC2640R2 schematic that I have attached, I am wondering which hardware is necessary to include if we want to bypass the XDS110 debugger by using the 10 pin connector to the CC2650 board. Let me know if this is unclear. On page 3 of the schematic, P5 should be the 10 pin connector that we are using. So do we still need to include P4 and associated hardware in order to connect to the CC2640 chip? Thanks

You need everyting on page 1, nothing on page 2, P5 on page 3 - nothing else, nothing on page 4.
