![]() The SDRAM must first be rewritten by zeroes if ECC is used to initialize the ECC metadata. Make the CPU overwrite the DRAM with zeroes in such a case. This scrubbing implementation turns the caches on temporarily, then overwrites the whole RAM with zeroes, flushes the caches and turns them off again. This provides satisfactory performance.
