General informations

Help text

This option enables the workaround for the 743622 Cortex-A9 (r2p*) erratum. Under very rare conditions, a faulty optimisation in the Cortex-A9 Store Buffer may lead to data corruption. This workaround sets a specific bit in the diagnostic register of the Cortex-A9 which disables the Store Buffer optimisation, preventing the defect from occurring. This has no visible impact on the overall performance or power consumption of the processor.
