https://devzone.nordicsemi.com/f/nordic-q-a/104807/qspi-read-write-synchronizationHi, folks! I have one simple (?) question - could I async read and write to QSPI simultaneously (for instance - read/write can occur as from ISR (ble, timer) and from app)? Maybe are some solutions there regarding this? Thanks!en-USTelligent Community 13Wed, 18 Oct 2023 11:32:53 GMThttps://devzone.nordicsemi.com/thread/451048?ContentTypeID=1Wed, 18 Oct 2023 11:32:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cbe941e0-0ca1-432b-b446-c61aa88cace6Einar Thorsrud<p>Hi,</p> <p>That will not work. You need to ensure that you do not try to use the same HW resource from different part of the code at the same time (for instance with a mutex, or letting a single thread handle access, or similar).</p><div style="clear:both;"></div>
