Part Number: LAUNCHXL-CC2640R2
What is the jumper settings to power up CC2640R2F Launchpad using BOOSTXL-BATPAKMKII? I program my CC2640R2F Launchpad with pwm led example program. I remove 5v and 3.3v jumper and then connect the BOOSTXL-BATPAKMKII to CC2640R2F Launchpad. The CC2640R2F Launchpad does not power up.

I remember I powered my CC2640R2F Launchpad before using 2AA battery and adjustable power supply. But, with all jumpers removed. So, I connect the BOOSTXL-BATPAKMKII to CC2640R2F LP (w/ led jumpers only) using connecting wires, see below. The pin interrupt and simple peripheral work in this setup.
I reviewed the BOOSTXL-BATPAKMKII pinouts and it will not in any way cause the CC2640R2F LP to not work. So, it seems CC2640R2F LP circuitry is not compatible with BOOSTXL-BATPAKMKII. However from my use the BOOSTXL-BATPAKMKII is compatible with TM4C Connected LP, MSP432P401R LP, and CC3220SF LP.
I was doing a simple project using CC2640R2F LP and BOOSTXL-BATPAKMKII and now it seems I have to scrap it. It would not look good if I make it work using connecting wires.
My apologies, as per the BoosterPack Checker the LAUNCHXL-CC2640R2 LaunchPad is incompatible with the Fuel Tank MKII Battery BoosterPack, as pin 34 on the LaunchPad is unavailable.
CE Pin of BOOSTXL-BATPAKMKII is connected to TMS Pin of CC2640R2F LP See, below. But, I removed TMS Jumper and still did not work. Anyway, I will try to isolate the root cause of the problem. Please, communicate this issue with the TI Launchpad Team. I also suspect that new CC26X2R is not compatible with BOOSTXL-BATPAKMKII.
Upon further inspection, I believe that the issue at hand is a conflict on pin 35 of the LAUNCHXL-CC2640R2. On the LaunchPad, this pin (labelled BPRST) is an active low reset, that is pulled up to 3.3V by a 100k resistor.
On the BOOSTXL-BATPAKMKII, this pin corresponds to EN1 (used to set the battery charge rate), and is pulled down to ground by a 10k resistor. This 10k pulldown resistor is constantly activating the RESET_N on your CC2640R2F, which is why your application is not running.
You should be able to resolve the issue by desoldering the zero-ohm link labelled "BP" on your LaunchPad. This effectively disconnects the LaunchPad's BPRST header pin from the CC2640R2F device's RESET_N pin.
Finally, I do not believe that the pin 34 conflict will cause you any issues, as this header pin on the LaunchPad (labelled TMS) is completely disconnected by default (see the unpopulated solder pads directly to the left of the TMS header pin).
