Cc2640r2f: (Beginner) Need help programming MCU from reel

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2640R2F

Hello,

I recently purchased a CC2640R2F Wireless MCU for use in a school project. I'm having trouble on understanding how exactly I am supposed to program the MCU without the Launchpad. I know that I can use Code Composer to write my code, but I'm unsure of how to transfer it to the MCU. What external devices will I need? How will this circuit look like?

I looked at the FAQ, but I'm unsure of how those debuggers work exactly. What is the difference between using UART and jTAG? I have soldered the MCU onto a breakout board, so I can use a breadboard for debugging. The MCU is in the RGZ package with 48 pins if that helps.

    Hi Khalique,

    You need a programmer (which typically is also a debugger) to program the device. One option is to use the XDS110 debugger which is included on the LaunchPad. The chips are typically programmed through JTAG after being assembled on a PCB.

    Note that running the CC2640R2F on a breadboard might not work well due to specific layout requirements for the DCDC regulator and the RF circuitry.

    Cheers,
    Fredrik

    Thanks!

    As a follow-up, are the layout requirements described in the datasheet? And I'm assuming the JTAG pins from the chip are going to be used with the XDS 110?

    There are layout examples in the datasheet. You will also find more reference design on the CC2640R2F product page (www.ti.com/product/cc2640r2f) in the Technical Documents tab. You should also take a look at the design resources on the BLE Wiki page: www.ti.com/ble-wiki

    Cheers,
    Fredrik
