Hi Greg, and all,
Confirming again that disabling POWER_SAVINGS and the board runs fine.
We spent the day here looking at the 32KHz crystal and it's all's good on a scope and frequency meter, dialing in at 32.768895KHz with around 14ppm.
We are using a different crystal from the reference design though. It's a ABS06-32.786KHZ-T and we've got it loaded with 18pF caps. See attached schematic (note that U2 is not stuffed). Any possible issues with that part?
Again, the same code (with POWER_SAVING enabled) runs perfectly fine on the CC2541DK-MINI board, but fails on ours. Note we have commented out any hardware calls to the accelerometer and instead just put in dummy data.
We're a little stuck. Any other suggestions?
Thanks,
Brian
