• Worked on OpenOcd Project. OpenOcd is an opensource tool to live debug the target (Similar to T32 / JTAG). We can use any frontend / GUI with OpenOcd project like eclipse, vscode etc. In Openocd already support for multiple architecture like ARM64, ARM32, x86, xscale, riscv etc. I added support for Q6 / Hexagon architecture (MODEM, CDSP, ADSP processors) in Openocd. In this project we implemented the Q6 Processor halt / Break, step, resume, register read / write, memory read / write, SW breakpoint,Call stack, HW breakpoint functionality. In Openocd there is support for gdb, as hexagon processor is supporting the lldb tool chain, so we added support for lldb remote debug server as well.
• Worked on Mindump feature for MODEM. Minidump (MD) is a best effort use-case to collect useful & pre-defined collection of data to enable first level of debugging.
• Worked as an System debug engineer in Qualcomm Solution(Qualcomm Hexagon/ARM9/11 DSP). Exp in debugging crashes/resets such as memory leak/stack corruption/task starvation/bus hang/device freeze,mips issue, QLINK issue, memory latency issue, device lockup issue, interrupt missing issue, corruption issue, bit flip issue, register state loss, Timeline missing issue, processor stall, Watchdog bite/Dog ,NOC error etc.
• Experience in advanced debugging techniques like ETM, ETB, SW Events, HW Events, live debugging using JTAG / EUD etc.

• Worked as an System debug engineer in Qualcomm Solution.
• Experience in debugging on Qualcomm Hexagon/ARM9/11 DSP.
• I worked for the System Debugging team and ensure that the end-product qualifies the defined acceptance criteria (in terms of containing the stability issues such as crashes/resets to an agreeable number for a given number of test hour runs). We analyze crash dumps & identify root cause of stability issues (such as memory leak/stack corruption/task starvation/bus hang/device freeze etc.) reported by test teams. It also involves the opportunity to interact with different test & technology teams to understand the test scenarios/reproducibility of crashes & follow-up on the fixes for the software or hardware defects found. We work on a variety of microprocessors/ Operating systems (Android, Rex, L4, Blast, QURT (Qualcomm specific)).
• Analysis and debugging of system level issue on Qualcomm SOC like mips issue, QLINK issue, memory latency issue, device lockup issue, interrupt missing issue, corruption issue, bit flip issue, register state loss, Timeline missing issue, processor stall, Watchdog bite / Dog , NOC error etc.
• Experience in working closely with HW/BSP team for debugging of system level issue.
• Experience in advanced debugging techniques like ETM, ETB, SW Events, HW Events, live debugging etc.
