Hello,
I'm following Section 10.5 of iMX Linux User Guide(Rev. LF5.10.52_2.1.0, 15 October 2021) to create an encrypted partition. I'm using an iMX7D based Eval Board, which is running Debian Buster and linux kernel version is 4.14.98. I followed steps for Kernel configuration and installed required packages. After booting with the new kernel, verification of build setup is failing. Below is console interaction.
root@myhost:~# grep -B1 -A2 tk- /proc/crypto|grep -v kernel
name : tk(ecb(aes))
driver : tk-ecb-aes-caam
priority : 1
--
name : tk(cbc(aes))
driver : tk-cbc-aes-caam
priority : 1
root@myhost:~# cd /; find -name "caam-keygen"
(It returns nothing)
I notice that Application Note is written for iMX8 EVK, with its own source repo and build system. In our case, we are using a customized linux build for iMX7D provided by board vendor. Hence we can't take the source code as it is given in the User Guide.
Is there any document detailing steps for CAAM supported disk encryption with a working linux build for iMX7 board.
Thanks
