Using wait_for_fds_ready() after each flash write or read?

[Ameer Usman]

Okay so I use fds for flash writing and wanted to ask should I use the wait_for_fds_ready() function after each operation and how critical is it?

Hi,

No need to do so no. The flash operations will be queued and scheduled automatically.

My only recommendation is that you for instance can use nrf_fstorage_is_busy(NULL) to check for pending flash operations before you go to system OFF and/or do do a soft reset. That way you ensure that all flash operations are completed before you go into a mode where pending flash operations may be "lost".

Best regards,
Kenneth
