Percepio to Present Device Firmware Monitor at Embedded World

Percepio will showcase their Percepio Device Firmware Monitor in Hall 4, Booth #305 at embedded world in Nuremberg, Germany from February 26–28.

Percepio Device Firmware Monitor is a new cloud service that provides IoT vendors with automatic feedback on runtime issues, both during testing and in deployed products. DFM makes it easy to report issues from the device software, resulting in alerts being sent to the developers with both an error message and a diagnostic software trace of the error.

DFM relies on existing services for secure cloud connectivity, storage and OTA updates. Initially, it supports IoT devices connected to Amazon Web Services (AWS IoT Core) and running Amazon FreeRTOS, but support for additional platforms is planned and can be provided upon request.

“Let’s face it – we can never be certain that any software is free of bugs. On average, 5% of the original bugs in firmware remain in the production code, despite all verification efforts. This can mean hundreds of bugs in the shipped product. You can always spend more time and money on verification, but the effort needed to find the last remaining bugs increases exponentially. The IoT trend further increases testing challenges, but also provides a remedy. IoT allows for automatic feedback from the field, that immediately makes you aware of missed bugs. This way, you can fix remaining bugs quickly and deploy an Over-the-Air (OTA) update with corrected firmware, before most of your customers even have noticed any problem,” said Johan Kraft, CEO of Percepio.
