Find the embedded problem before committing to a rewrite
Bring a board revision, supply conditions, serial or boot logs, reproduction steps, the current firmware or source availability and the intended behavior. We isolate whether the issue belongs to startup, DDR, driver, electrical level, protocol or application interaction.
Scoped work
- Review logs and reproduce the fault on a defined board and software version.
- Record evidence and excluded causes, then propose a hardware revision or software adaptation where needed.
- Agree on changes and repeatable verification steps before expanding the project.
Typical environments include MCU firmware, embedded Linux/Buildroot, Android BSP and device communication. Final scope and source-code delivery are agreed per project.
