CC2650MODA: CC2650MODA stops working when not debugging connected

Part Number: CC2650MODA
Other Parts Discussed in Thread: CC2650, BLE-STACK

Hi,

I have got the simple_peripheral app with some basic mods running in a CC2650LaunchPad for days, but when I port the code to the MODA if the debugger is not connected stops working in a couple of minutes.

The basic app just have the heap increased and the compiler option BOOSTXL_CC2650M for the MODA variant.

The board has a 100K pull-up resistor between RESET and VCC.

When the MODA stops working, even the debugger is in a strange mode and needs to be reset in order to reprogram the board.

Any advice how to debug this?

    Hi,

    We are using the basic simple_peripheral demo app with the 5.2.6 compiler, and after a while (minutes in case of the MODA and hours in case of the LP) the boards stop working when the JTAG pins are unconnected(floating). In MODA module we are using a 100K pull-up resistor between RESET and VCC

    Hi,

    Have you applied the workaround from the "Known Issues" page on the TI BLE Wiki for BLE-Stack v2.2.1?
    Also, what are your ADV parameters?

    Best wishes
