Description of defect

While running the blinky example (https://github.com/ARMmbed/mbed-os-example-blinky) the current consumption of the MCU is constant (~500 uA).

What is expected to happen is during blinking the current consumption should change drastically. Extremely low during LED off and higher during LED on.

It seems like the OS is never actually entering any kind of sleep - normal or deep. When running the ambiq SDK RTOS blinky example the current consumption is as expected.

Target(s) affected by this defect ?

Currently I'm using the ambiq apollo3 EVB board (Rev 1.7) to test

Toolchain(s) (name and version) displaying this defect ?

gcc version 9.3.1 20200408 (release) (GNU Arm Embedded Toolchain 9-2020-q2-update)

What version of Mbed-os are you using (tag or sha) ?

I'm using the ambiq-apollo3-dev branch (hash b5710d7)

What version(s) of tools are you using. List all that apply (E.g. mbed-cli)

mbed-cli version 1.10.4

How is this defect reproduced ?

Build the blinky example (https://github.com/ARMmbed/mbed-os-example-blinky). Flash it to the board and measure current consumption.
