So that leaves is up to the application to keep track of which operation the flash event belonged to. You may be able to utilize the context pointer for this (pointer is provided when you register SoC observer(s). Are you using fstorage or FDS in your application?</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
