I can help you stabilize and debug your TI C2000 (F28P65x dual-core) firmware running in Code Composer Studio, focusing on real-time control reliability, ISR timing integrity, and power-electronics stability. My approach would start with a structured analysis of your existing project using CCS debug tools (JTAG/XDS), real-time watch variables, and peripheral register inspection to reproduce and isolate the three critical issues: PWM shutdown during transient load steps, ADC sampling inconsistencies affecting MPPT behavior, and watchdog resets caused by ISR conflicts across the dual-core architecture. From there, I would audit the interrupt pipeline, ePWM–ADC synchronization, and shared memory communication between cores to identify race conditions, missed triggers, or timing violations. For the PWM shutdown issue, I would verify trip-zone configuration, dead-time handling, and fault latch clearing logic during fast transients. For ADC misreads, I would focus on SOC trigger alignment, sampling windows, and potential DMA/interrupt contention affecting result registers. For watchdog resets, I would examine ISR execution time, nested interrupts, and cross-core synchronization, ensuring that no blocking calls or priority inversion is occurring.

Hi, I have experience working with embedded systems, real-time firmware, and communication protocols on TI C2000 platforms using Code Composer Studio. I can help develop and debug the F28P65x project including ADC sensing, ePWM generation, dual-core programming, IPC communication, and CAN/SPI/I2C integration. I can investigate the PWM shutdown issue, ADC misreads, and watchdog resets through ISR timing analysis, synchronization checks, and real-time debugging using JTAG/XDS tools while keeping execution timing optimized and stable for power-electronics applications. Happy to review the existing CCS project and discuss the best implementation and debugging approach for stable inverter operation.

**C2000 Power Stage Firmware Remediation** * **Transient PWM Shutdown:** Fix the overcurrent/trip-zone ISR logic triggering false positives during fast load steps, ensuring tight boundary checks without cutting power prematurely. * **ADC/MPPT Anomalies:** Correct ADC sampling windows (ACQPS) and trigger timing to eliminate noise injection from switching events, stabilizing the MPPT input. * **Watchdog/ISR Timing:** Profile CPU1/CPU2 ISR execution times. Optimize context switching and move non-critical I2C/CAN/SPI tasks to the background to prevent watchdog timeouts. * **Dual-Core & IPC Architecture:** Optimize CPU1 handling high-frequency control loops (ADC/ePWM) while offloading telemetry and communication protocols to CPU2 via streamlined, lock-free IPC RAM buffers. **C2000 & Power Electronics Track Record** Expertise includes writing production C++ and bare-metal C for C2000 MCUs in CCS, tuning complex digital power topologies (bi-directional LLC, 3-phase inverters), and using JTAG/XDS110 to catch nanosecond-level timing faults.
