Hi,
In our application based on IMXRT1170, we plan to have LittleFS over the Flash Memory. Since we plan to have user data being saved to be encrypted and decrypted as a routine feature, want to check if using the Inline Encryption Engine be an appropriate utility? Any other insights/suggestion will also be helpful.
Regards,

Hi @kotalamit ,
Yes, this is because flash programming use IP command, it doesn't use AHB bus. IEE can't help. You have to use IEE region 0 or other peripherals or software to encrypt the plaint text first, then do like the demo.

Hi @jingpan
Thanks for the reply. With reference to the example, you mentioned; in that there is only decryption of the data stored in flash. No encryption for the flash data storage.
Additionally, in reference manual section 7.10 it is mentioned as decrypting only over Flex SPI.
