Hi john_wick

for encrypted storage usage one can look at AN12714

i.MX Encrypted Storage Using CAAM Secure Keys

Best regards

Hi igor,

Thanks for your response. I have tried that. But it didn't work for me.

I was referring to AN12714 Rev0. I get the below error while trying to generate keys.

I have attached list of my kernel modules for reference. I did search for this error, but in the forum, lot of people suggested to upgrade 5.4.47 kernel for this to work. Please confirm.

Also, for the actual question I posted regarding ecryptfs error, the problem was the kernel module for ecryptfs was not set.

After setting, CONFIG_ECRYPT_FS=y, it started working as expected.

However, Igor, I would like to know the solution for the below error regarding dm-setup process as mentioned in AN12714.

Thanks in Advance
