Thanks for the tips, that confirms my long suspensions that the size of the image could be the cause of the problem, my working zImage size is 8MB, my failing zImager-initramfs size is 35MB. How did you remove the 10 MB size restriction? I checked your core-image-minimal-initramfs.bbappend, there is no sign to remove 10 MB size restriction. You have a resize-rootfs.service, but I am not sure that is the one for fixing the 10 MB size restriction. The edison-image-minimal.bb has the IMAGE_ROOTFS_SIZE = "1048576", sorry for my dumb, is that size for 1048576 KB (1GB) or 1048576 B (1MB)? > The init script is here: > https://github.com/edison-fw/meta-intel-edison/blob/master/meta-intel-edison-distro/recipes-core/initrdscripts/initramfs-framework/init > > The init script loads modules, waits for the disk with the rootfs to > appear and mount it.

I am confident that the 10 MB size restriction is the problem, I am not clear where that 10 MB size restriction is defined and how to fix the size restriction, appreciate your helps. > To build everything edison-image-minimal triggers build of u-boot, > kernel, rootfs, initramfs and kernel-with-built-in-initramfs. > Search for 'init' and 'live' and find the needed lines in > https://github.com/edison-fw/meta-intel-edison/blob/master/meta-intel-edison-distro/recipes-core/images/edison-image-minimal.bb I looked at the init script, but not clear if it is critical for fixing that issue or not. My init is the symblic link to /lib/systemd/systemd in imx6. Thank you very much.
