Magnus Edlund

Participating in a Core SW team developing the control software for the next generation of Borg Warner All-Wheel drive coupling.

Software development for a Revolving Door control system. Participated in a team that developed a new distributed control system for door control. The system contained several Cortex-M processors connected to a CAN network for sensor inputs and motor control.

Software development for a Biometric Embedded Platform targeting resource constraint systems like Smart Cards. The work included integration of fingerprint authentication algorithms and development of driver software for Fingerprint Cards fingerprint sensors.

A customer to Sigma Connectivity outsourced the development of an advanced wearable device. The device include BLE connectivity, touch screen, haptics, sensors and LEDs. Magnus coordinated a team of developers that was responsible for the device driver development. The work included device bring-up and device driver development.

Sigma Connectivity performed a concept study for a new Android phone based on customers’ requirements. The concept work was to identify, evaluate, select solutions and components (both hardware and software) to fulfill the requirements. The work included software system analysis and defining software requirements.

Sigma Connectivity developed a new variant of an existing LTE wireless module for automotive industry to an international customer. The customer wanted extend the band configuration to support LTE TDD band in China. Magnus was responsible for the software development. The development was radio front end configuration in the modem software to support the LTE TDD band.

Sigma Connectivity developed a prototype of a LTE indoor radio cell for an international customer. The prototype introduced new RF design and components to improve an existing product. Magnus was responsible for the software and performed system analysis, handle requirements to external developers, software configuration and software bring-up.

Participated in a team responsible for integrating vendor software from Google and Qualcomm. The work included bring-up of new Android releases, bring-up of operator specific HW variants, device configuration, trouble shooting and debugging. It has given a broad knowledge of the Android platform and has required collaboration with many different teams within the organization. The integration was done for devices based on Qualcomm Snapdragon platforms.

Troubleshooting and debugging of software for Sony Mobile Android devices. Participated in a System Team responsible for solving complex software problems on a system level to secure product quality and performance. Used several Android and Linux debug tools like Crash utility, GDB, DDMS and strace to identify and solve problems in almost all areas of the phone software. It has involved work with Linux Kernel drivers, Linux Kernel configuration, Android Framework and Android Applications.

Troubleshooting and debugging of software for Sony Ericsson mobile phones. Participated in a team responsible for solving software problems on a system level during project phases from early SW bring-up to RCA analysis of return rate issues after launch. Used several tools like Lauterbach/Trace32, GDB and post mortem crash analysis to identify and solve problems in almost all areas of the phone software. It has involved work with Linux Kernel drivers, Linux Kernel configuration, Android Framework, Android Applications, OSE and J2ME applications.

Software development for an intelligent Pad Wear Sensor used in brakes for heavy trucks and trailers. Responsible for all software development.
