    Corrupt Flash Data

    udo.preussner

      Hi All

      we use a PSoC4 BLE Module in a simple BLE application. We have installed a uart-bootloader component, which communicates with a host uC, to update firmware in the field.

      In the application-hardware we have different suplies for the host and the BLE. The voltage rising of both supplies may sometimes not proper, but the internal brow-out circuit should prevent any corruption of flash data in such cases.

      Now we have the phenomenon that in really rare cases one data-row is damaged. It is always the configaration-row in the top area of the flash memory.

      Does anyone have a smiliar experience or an idea what can be wrong?

       

      Thanks!
