Abstract
An embedded electronic device, a boot method, and an electronic device readable recording medium with a stored program are provided. A processor in the embedded electronic device executes a plurality of stage boot procedures after the embedded electronic device is powered on. Each of the stage boot procedures includes: executing current-stage boot firmware; reading a test request message and a firmware location message from a first memory; loading next-stage boot firmware according to the firmware location message in response to the test request message being a current-stage request; and updating the test request message to a next-stage request and updating the firmware location message to a next boot firmware location when the loading of the next-stage boot firmware succeeds, or otherwise, updating the test request message to a failure message and soft rebooting the embedded electronic device.
