Understand ARM processor family. Assembly language knowledge a plus. ARM Cortex family knowledge a plus.
Understand general on-chip debugging procedure and troubleshooting. Ability to debug C program on Embedded Real Time Systems using JTAG, Trace32, etc.
Ability to use Version Control Software: Perforce or equivalent.
Ability to use common development and test tools: Perl, debuggers, and compilers,
Ability to write and debug Software Generation program: GNU Make, SCons
Ability to use wireless communication test equipment, analyze test logs and isolate test failures.
Ability to communicate clearly with diverse group of software development and test teams
Organize effectively, and document work thoroughly
For day-to-day work,
- Understand and execute daily engineering builds based on pre-defined requirements. Familiar with ARM family compiler/linker usage.
- Resolve the dependency and follow up with the teams. This requires understanding trade-off between maintaining consistent APIs and reducing coupling.
- Sanity test the builds, and report issues. This requires on-target debugging and provide logs at code level.
- Understand Apps and concurrency of Apps. This requires isolating problems to a particular apps.
Initial debug and classification of test failures, then enabling software development teams to debug further, Create perl scripts to analyze test results to allow quick indication of pass/fail results.
