Memory and Timing Debugging

Read the shared embedded contract and keep source/build, device and physical evidence separate.

Read runtime evidence. Preserve the failing build, workload, allocation/timing trace, reset cause and reproduction. Identify whether the fault is exhaustion, fragmentation, overwrite, blocking, starvation or measurement distortion before changing task priorities or heap size.

Capture minimum free heap, largest free block where supported, stack high-water marks with the port's units, queue depth/drops and timestamped task/state events. A free-heap total alone does not establish an allocation fits. Inspect allocator and capability pools; PSRAM and internal DMA-capable memory are not substitutes.
