Worked on stabilizing the xsdb-based debugging workflow in the telink-semi/zephyr repository by addressing a critical issue in the Xsdb Runner’s ELF parameter handling. Using Python and leveraging skills in command line tools and scripting, ensured that the ELF file is consistently passed to the xsdb command, regardless of FSBL or bitstream presence. This involved updating the command construction logic in xsdb.py and aligning related tests to reflect the corrected behavior. The fix reduced intermittent failures and improved automation reliability for firmware validation, resulting in a more robust and predictable debugging process for embedded development and testing workflows.
