Part Number: MSP430F2001

Hi,

How to wake up MSP430F2001 from LPM4 mode? Can we wake it up by GPIO?

It has 10% failure issue in my customer that software is breakdown after running for 2 days. No response even trigger by GPIO. Watchdog is disabled. It can be recovered by reset or power on cycle.

Where should we focus on to check firstly? Thanks.

    Hi Daniel,

    I have some questions about the issue:

    • You mention a 10% failure rate - does that mean not all devices are experiencing this issue?
    • You mention after 2 days the GPIO becomes unresponsive and does not fire an interrupt to wake up from LPM4. Before this time time is the GPIO interrupt working as intended?

    Thank you,

    -Chris
