Hello Yocto community developers, I am currently working on the task of porting an existing build system to Yocto to create customized Linux distribution for an embedded product. I have successfully created a bare box image, the kernel and root file system image and the system startup is working fine.
I am now investigating on creating the initramfs using Yocto and have gone through the Yocto documents for the same. Adding the options : INITRAMFS_FSTYPES = "cpio.gz" INITRAMFS_IMAGE = "custom-initramfs" --> my recipe which inherited core-image.bb recipe Results in the creation of 'custom-image-20170120105621.rootfs.cpio.gz' file. We are using initramfs to run a script which before mounting the root file system checks for ima policy and also responsible for loading the evm-keys. In short, the initramfs contains a script which is executed before mounting the main root file system. So I think I need to follow a different procedure than the one I mentioned above for my use case. Also we are using systemd as the init system and for the initramfs I don't need sysv or systemd as all I will do is running a script in initramfs. Is there a better way of creating this structure in Yocto, any information would be helpful. Mit freundlichen Grüßen / Best regards Vinothkumar Eswaran BEG-PT/PJ-IOT1 Tel. +49(7062)911-02
