I am trying to boot into an image using the following commands:
setenv bootcmd "load mmc 1 0x82000000 swupdate-image-imx6ull14x14evk-20230206204748.rootfs.ext4.gz.u-boot;load mmc 1 0x82a00000 imx6ull-14x14-evk.dtb;load mmc 1 0x83000000 zImage;setenv root /dev/ram0;setenv rootfstype ext4;bootz 0x83000000 - 0x82a00000"
saveenv
print bootcmd
run bootcmd
This starts a kernel, finds and image and attempts to run it. However my issue is

I cannot seem to properly set the root= parameter. I have tried setting it in and out of my bootcmd. I am not 100% of my syntax but I cannot find an example to say I am wrong. Can anyone point me to my mistake?
The kernel command line is defined by the environment variable bootargs.

Can you please show the kernel command line?

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
I can't know what is the problem...
Can anyone help me ??
Thanks a lot !
This problem is solved.
It was simply a problem because NFS Protocol v2 was disabled.
After activating Protocol v2 of NFS Kernel Server, I confirmed that it is mounted normally.
And I heard this site is for code and programming so I will ask another site(unix.stackexchange.com) when I have a problem like this.
Thanks a lot!
I am trying to build an embedded Linux to be run on PocketBeagle using Buildroot; and following the instructions in (source1). The resulting images are copied then to the uSD-card.
When inserting the uSD-card in the Pocketbeagle and monitor the booting process via a serial connection; I got the following error:
No filesystem could mount root, tried:
ext4
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1)
---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1).
The used resources are:
Buildroot: 2018.02
File system: ext4
Bootloader: U-Boot (custom version 2018.01)
Kernel version: 4.14.24
Applying all the patches stated in source above and can be found in (source2):
- 0001-Stripped-back-pocketbeagle-devicetree.patch
- 0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch
- 0002-U-Boot-BeagleBone-Cape-Manager.patch
- 0003-pocketbeagle-tweaks.patch
Runing the build results in the following files and images:
MLO: First stage bootloader
U-boot.img: Second stage bootloader
uEnv.txt: U-boot environmnt
zImage: Linux kernel image
am335x-pocketbeagle.dtb: Linux kernel Device Tree Blob
rootfs.ext4: Root filesystem image
The uEnv.txt is as follows:
fdtfile=am335x-pocketbeagle.dtb
bootpart=0:1
bootdir=
bootargs=console=ttyO0,115200n8 root=/dev/mmcblk0p1 rw rootfstype=ext4 rootwait
uenvcmd=run loadimage;run loadfdt;printenv bootargs;bootz ${loadaddr} - ${fdtaddr};
Then by using genimage in buildroot (and rebuilding) to generate the uSd-image that contains two partitions:
1. FAT partition containing the bootloader images, the kernel image and Device Tree
2. Rootfs partition containing the root filesystem ext4
The resulting image is called sdcard.img is copies to the uSD-card by using program etcher (etcher-electron-1.4.3-x86_64.AppImage) or by (sudo dd if=output/images/sdcard.img of=/dev/mmcblk0 bs=1M)
I have used two different uSD-cards to test the build, but the result was the same:
1. Kingstone 32 GB (SDHC 10)
2. Sandisk 16GB (SDHC 10)
It's worth to say that I have used the same uSD-cards to load the original image of the PocketBeagle from the official site and boot from them, the cards boots without problem.
Any idea to help is highly appreciated.

[ 1.858913] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1)
[ 1.867873] ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1)
The failure to mount the rootfs is occurring because the correct partition of the SDcard has not been specified.
In the kernel command line, the kernel is (incorrectly) instructed to find the rootfs in the partition corresponding to /dev/mmcblk0p1.
bootargs=console=ttyO0,115200n8 root=/dev/mmcblk0p1 rw rootfstype=ext4 rootwait
and
[ 0.000000] Kernel command line: console=ttyO0,115200n8 root=/dev/mmcblk0p1 rw rootfstype=ext4 rootwait
However the mmc subsystem reports that there are two partitions on your SDcard, and the boot log reports the device names of these partitions for you twice.
First:
[ 1.635560] mmc0: new high speed SDHC card at address 0007
[ 1.644119] mmcblk0: mmc0:0007 SD32G 28.8 GiB
[ 1.655081] mmcblk0: p1 p2
And then:
[ 1.720670] List of all partitions:
...
[ 1.828679] b300 30228480 mmcblk0
[ 1.828690] driver: mmcblk
[ 1.835867] b301 16384 mmcblk0p1 00000000-01
[ 1.835877]
[ 1.843044] b302 524288 mmcblk0p2 00000000-02
So the kernel command line (through bootargs) should specify the second partition, /dev/mmcblk0p2, rather than the first partition for the rootfs.
Since the storage area for your U-Boot environment has not been properly initialized (i.e. the "Warning - bad CRC, using default environment" messages) (or your uEnv.txt file is missing or corrupt), U-Boot is booting the Linux kernel with a hardcoded bootargs value that is defined in your board's configuration file.
You could either edit that file and re-build U-Boot, or abort the autoboot and use
setenv bootargs console=ttyO0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait and saveenv commands to correct this mis-specification.
I wrote a kernel module which works as expected. But I want that to be loaded at the beginning of the boot process. So I moved this code to
OpenWRT/build_dir/target-i386_geode_eglibc-2.19/linux-x86_alix2/linux-3.10.49/arch/x86/platform

[ 0.108879] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009
[ 0.108879]
I think you have put this in kernel source directory. You should place this in drivers/gpio/ in kernel source. Then add the entries in Kconfig and Makefile of drivers/gpio/ directory. In Kconfig, you can specify the dependency. Selecting it with make menuconfig, you will be able to compile this module as a part of kernel, and it will be loaded at boot-time when kernel is loaded. You can decrease the time further in this case using early_initcall() instead of module_init().
If you are not putting this at kernel source (i.e. not building the driver as part of kernel), then you should call this using "insmod my_module.ko" in a shell script, and put it in init.d and call it at your desired runlevel.
I get the following error while booting linux-3.14.4 on FPGA ZC706. I have build all tools following ways:
Rocket-Chip:
$ Latest master branch is checked out and generate boot.bin
riscv-gnu-toolchain:
$ ./build.sh (riscv64-unknown-elf)
$ make linux (for riscv64-unknown-linux-gnu-gcc)
Linux kernel:
$curl -L https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.14.41.tar.xz | tar -xJkf -
$ cd linux-3.14.41
$ git init
$ git remote add origin https://github.com/riscv/riscv-linux.git
$ git fetch
$ git checkout -f -t origin/master
$ make ARCH=riscv defconfig
$ make -j12 ARCH=riscv vmlinux
Root disc image:
$ dd if=/dev/zero of=root.bin bs=1M count=64
$ mkfs.ext2 -F root.bin
Booting:
1. First copy all files (vmlinux, root.bin, boot.bin, devicetree.dtb, uImage, uramdisk.image.gz) into sdcard.
(2) $ mkdir /sdcard
$ mount /dev/mmcblk0p1 /sdcard
$ ./fesvr-zynq +disk=/sdcard/riscv/root.bin bbl /sdcard/riscv/vmlinux
Booting starts, but stuck at a point. The following are the booting error

Can anyone help me, whether I miss anything. I also tried with
linux-3.14.33; the same error comes
I can now boot kernel on SPIKE ISA as well as FPGA. I omit some steps while building root.bin mentioned at https://github.com/riscv/riscv-tools.
$ dd if=/dev/zero of=root.bin bs=1M count=64
$ mkfs.ext2 -F root.bin
will generate empty root.bin. We need to mount disc image and complete the file systems after completing busy box building as mentioned at https://github.com/riscv/riscv-tools
