I have a RT5350F router device (Hardware is almost the same as Nexx WT1520). It used to run Zyxel Keenetic 4G II firmware, and now I decided to reflash OpenWRT to it.
I tried a lot of versions, and all of them don't boot any further than this:

I reflashed U-boot as well, which didn't really help.
Some other OpenWRT firmwares boot, but crash right away, saying "Not enough RAM".

I am following this guide to run a minimal linux kernel on top of QEMU, and keep running into the same issue. I have also tried other similar tutorials and end up with the same panic. Since the panic seems to be related to the /init script, I have tried swapping this out with a (statically linked) binary but still end up with the panic. The only thing I have done differently from the tutorial is using the latest stable version of BusyBox (currently 1.34.1). The text of the panic is here and linked below. If anyone has any insight on this that would be great!

Additionally, I have actually tried very similar steps on a completely different computer, so I'm pretty sure there is something I am missing in-general. Both machines are running Gentoo but I have successfully used QEMU to emulate other existing operating systems on both devices (so I think I can exclude a missing kernel configuration)?
Add execute mode to /init file before you build CPIO initramfs:
chmod +x <path-to-your-initrd-root>/init
I am trying to manually build a mainline kernel and boot in Pine64_Plus board.
Linux kernel unable to mount the boot partition. And wierdly it doesn't display any partition under available partition in boot log.
I did the below steps.
Cloned the linux mainline git repo
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git --depth=1
Installed the cross compiler tool chain.
and then..
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make defconfig
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j4 Image
Generated the dtb
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j4 dtbs
Generated the kernel modules
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4 modules
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- INSTALL_MOD_PATH=ker_mod_temp_dir make modules modules_install
Partitioned the SD card like below
I kept the MLO, Uboot and firmware files in the boot partition.
I downloaded the ArchLinux rootfs from here
I copied the downloaded rootfs to the ROOTFS partition of my SD card.
sudo cp -rT <path-to-downloaded-rootfs> /media/user/ROOTFS
I copied the linux image and dts folder from /arch/arm64/boot to boot folder in the rootfs.
I copied the kernel modules to roots
sudo cp -rT ker_mod_temp_dir /media/user/ROOTFS/lib
I tried to boot the board with the SD card.
Uboot successfully boots up. I gave the below commands in Uboot to load the kernel.
setenv kernel_addr_r 0x42000000
setenv dtb_addr_r 0x48000000

doesn't display any partition. What could be the reason?
mmc drivers are selected in the config as below
CONFIG_MMC_BLOCK=y and CONFIG_MMC_SUNXI=y
What am i doing wrong?
Try adding the kernel command line option rootwait to bootargs so that the kernel does not immediately give-up and instead waits forever hoping the root filesystem appears. It might be that kernel did not wait long enough during boot-up for the SD card to appear.
[mmc]: MMC Device 2 not found
[mmc]: mmc 2 not find, so not exit
...
Kernel command line: console=ttyS0,115200 earlyprintk ignore_loglevel root=/dev/mmcblk0p2 rootfstype=ext4 rw
...
VFS: Cannot open root device "mmcblk0p2" or unknown-block(0,0): error -6
It is possible that you need to delay and rootwait may solve it. However, this is the exact situation that initramfs is attempting to solve and is at least a 'debug' path for you. If you create an initramfs image and attach it to the Linux binary you can use a shell to probe Linux's partition layout and/or delay mounting the rootfs until it is ready. You can do other things in the initramfs like add a splash screen, parallel the USB infrastructure like module loading of detected devices with the rootfs mounting. This will make your boot faster as well as giving you a tool to diagnose booting.
It also look like u-boot can not see the /dev/mmcblk0p2 either. The fact that both u-boot and Linux seem to be complaining could indicate that something went wrong with the partition generation. It is definitely useful to compare boot logs versus a know working version as suggested by sawdust. For instance, timing/clocks, supplies or pinmux may not be set for the MMC and this can prevent the device from being recognized. It seems you have the driver, but not the device from the logs. Ie, no mmcblk0 anything. See: DTS mmc entries for some values that you may need to define for your board. The fact that Linux is found would seem to contradict this, but it would be useful to add the MMC device entries that the system is using. I would expect some output in the kernel logs. Another possibility is that something was built as a module and is expected to load to make the MMC accessible.
Getting a minimal initramfs will give you some shell tools to diagnose. You can use klibc or buildroot, etc to make a small initramfs that will let you look around the Linux device nodes, proc and sysfs value to diagnose things. Unfortunately, there are many things that may go wrong here. However, since you have Linux booting adding an initramfs is usually straight forward, even if you don't keep it for the final system.
I used Spike to boot linux using the riscv tools but the linux boot sequence seems to stop at Bootconsole[early0] disabled.
I tried adding kernel command line root=/dev/vda ro console=ttyS0 but didn't work. The same console settings works in QEMU. Also checked the .config file for the line CONFIG_HVC_RISCV_SBI=y. It was there. Still coulnd't get past it.
Tried with Linux kernel version 4.19 to 5.2. No luck. Am I doing something wrong here?
Steps I followed:
Compiled linux with Riscv toolchain
compiled riscv-pk with ../configure --host=riscv64-unknown-elf --with-payload= [path to vmlinux]
used "Spike bbl" to start spike image.
Please let me know if any more info is required.
Sorry, noob here.

This might be because Virtual Terminal is enabled in your linux config. Disabling Virtual Terminal might solve your issue.
In Linux make menuconfig go to :-
Location:
-> Device Drivers
-> Character devices
and Disble Virtual terminal .
Symbol: VT [=y] n
Type : bool
Prompt: Virtual terminal
As mentioned previously, the reason is that VT is enabled so kernel has a dummy VT framebuffer that simply goes nowhere, but you don't have to disable it. console=ttyS0 will also not work, since SPIKE doesn't emulate it. Note that this won't work on the HiFive Unleashed, either, since serial terminals there are ttySIF0 and ttySIF1. What you want is console=hvc0 and SPIKE will be able to continue from there, e.g. in your kernel .config:
CONFIG_CMDLINE_BOOL=y
CONFIG_CMDLINE="earlyprintk console=hvc0"
CONFIG_CMDLINE_FORCE=y

It is clear that there is an error with the "mounted filesystem":
zynq> EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) on device 179:2.
Trying to move old root to /initrd ... /initrd does not exist. Ignored.

Why does this happen? Why before I can do everything with the system and, suddenly, I have a crash? Yes, the system crashes when I am doing nothing on it and not when I am working with it.
Are there some advice to solve this? to not to have anymore these crashes?
From the Linux Kernel Command line I can see "root=/dev/mmcblk0p2" and also the target is started with initial ramdisk image "uramdisk.image.gz". So the init process or scripts inside ramdisk image should be responsible to mount the real file system from SD i.e. from /dev/mmcblk0p2 and remove the used memory of ramdisk. To narrow down the problem, you need to analyze the steps taken in ramdisk image to mount the real filesystem and make sure you have the proper RFS flashed inside SD in /dev/mmcblk0p2. I can also seen some missing directories to mount the /dev/mmcblk0p1 and /dev/mmcblk0.
++ Mounting filesystem
mount: mounting /dev/mmcblk0p1 on /mnt failed: No such file or directory
mount: mounting /dev/mmcblk0 on /mnt failed: No such file or directory
In simple words, check the init scripts inside the ramdisk image and make sure the RFS is mounted properly.
I am working on building an linux for powerpc 8641d board. My U-boot has been modified to recognize 1 GB of memory(RAM) and it does. But Linux 2.6.28 crashes when mem=1024M is passed as boot parameter from u-boot. I have specified the memory size as 0x40000000 (1GB) in DTS file. Can any one help me to findout the reason?
But the same Linux image works when I specify bootargs as 'mem=256M'. But OS idetifies the total memory of 256MB only but I want it to identify complete 1GB memory.
Here is the dump of linux boot: ** It hangs at this point:
