Hi, I am trying to bring up a Yocto build on a custom i.MX7 board that uses NAND flash. I am using yocto from fsl-community-bsp (Morty), MACHINE=imx7dsabresd (modified). Here is part of the machine config I use:
IMAGE_FSTYPES := "ubifs cpio.gz" MKUBIFS_ARGS = "--squash-uids --min-io-size 2048 --leb-size 126976 --max-leb-cnt 940" KERNEL_CLASSES ?= " kernel-fitimage " KERNEL_IMAGETYPE := "fitImage" # imx7koji-initramfs is defined as a recipe in recipe-core/image/ INITRAMFS_IMAGE = "imx7koji-initramfs" I created append recipes to customize u-boot (u-boot-imx_2016.03.bbappend); to add a new device tree and change kernel config (linux-imx_4.1.15.bbappend). Yocto builds fine, however when tried to boot the board, the kernel is not able to run "/init": ... Freeing unused kernel memory: 188K (804f7000 - 80526000) request_module: runaway loop modprobe binfmt-464c request_module: runaway loop modprobe binfmt-464c Failed to execute /init (error -8) request_module: runaway loop modprobe binfmt-464c Starting init: /sbin/init exists but couldn't execute it (error -8) request_module: runaway loop modprobe binfmt-464c Starting init: /bin/sh exists but couldn't execute it (error -8) Kernel panic - not syncing: No working init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance. Rebooting in 5 seconds.. I made sure the initramfs contains "/init" (it is a soft link to /sbin/init which is a soft link to /sbin/init.sysvinit). I also checked the architecture of the kernel and the user space init are the same (32bits), but still the board resets. $ file ./linux-imx/4.1.15-r0/build/vmlinux ./linux-imx/4.1.15-r0/build/vmlinux: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, BuildID[sha1]=9d64e3cab02bd4ab3c548b18c1dc5228116cf913, not stripped $ file sbin/init.sysvinit deploy/images/imx7koji/mp/sbin/init.sysvinit: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 3.2.0, BuildID[sha1]=610388df391c1223d7522530fde8097537356288, stripped Also enabled the kernel to support ELF. Still the board reset with the same error. CONFIG_BINFMT_ELF=y CONFIG_BINFMT_SCRIPT=y Any ideas on the root cause of this issue, did I miss something in the config?
