LPC55S69 libpower_hardabi.a

Hi,

I use lpcxpresso55s69_power_manager_lpc with lpc55s69_evk. I am using SDK 2.7.

sleep mode, deep sleep mode, deep power down mode work well.

But it cannot wake up from power down mode.

I change to use libpower_softabi.a and change the project config, architecture to FPV5-SP-D16(soft ABI), then it can wake up from power down mode.

Is the libpower_hardabi.a buggy or do I need to do any extra configuration?

Hello Francis,

Could you please confirm how you are attempting to wake up from power down.

I have attempted from my end but it works without any problems using the hardabi library.

I can wake up using the reset or the S1(ISP button).

I am using the SDK 2.7.0 and the LPCXpresso55S69 Rev A1

Best Regards,

Sabina
