Overview

The validation suite implemented in sram_validation.c treats the external AS6C4008 as a raw byte-addressable memory device. These tests are intentionally destructive and are designed to prove that the FMC-connected SRAM behaves correctly before the firmware relies on it for structured application data.

Validation Philosophy

The validation suite answers the question:

"Does the external SRAM hardware behave correctly as memory?"

These tests are not primarily concerned with linker placement or structured object usage. They are focused on:

address correctness
read/write correctness
full-range coverage
representative bit-pattern stress
repeatable console-visible diagnostics

The retained integration-dump diagnostics complement this layer, but they do not replace the destructive raw-memory validation flow.
