Three things: [1] The initramfs is NOT the initrd (te second one is the temp stage in booting the linux to mmcblk...); [2] There are some config parameters you need to set up in your kernel .config file: https://github.com/ZoranStojsavljevic/bbb-yocto/blob/master/custom/config-initramfs [3] The command line is formed in u-boot or in grub2, or in your Linux boot loader (you need to add some lines in ash u-boot config script, as the following example): https://github.com/ZoranStojsavljevic/bbb-yocto/blob/master/custom/u-boot.ash
