When kernel run finished, a code "echo 1 > /proc/sys/net/ipv4/ip_forward" execute in the last of /etc/rc.sh. About restart 10 to 20 times , the kernel will crash once when run this code.
I don't know how to resolve this problem, because the most times board start success.
Following is the log from board to kernel crash. Can somebody give me some advice? Thanks!

I have an ARM based embedded system with 1GB of memory. The kernel, dtb file and root filesystem (initrd.gz) are stored in a FIT file in flash. U-boot loads the FIT into ram and boots the kernel.
I'm having a problem where if I slightly increase the size of my root file system my system no longer boots and I can't figure out where I'm exceeding a memory boundary.
This configuration works (initrd.gz size ~30MB) u-boot output:
Booting using the fdt blob at 0x20683744
Loading Kernel Image ... OK
Loading Ramdisk to 8e1d0000, end 8ffffebd ... OK
Loading Device Tree to 8e1bf000, end 8e1cf118 ... OK
Kernel output:
[ 2.761235] RAMDISK: gzip image found at block 0
[ 5.345119] EXT4-fs (ram0): mounted filesystem without journal. Opts: (null)
After increasing the size of initrd.gz this configuration doesn't work (initrd.gz size ~35MB):

Loading Ramdisk to 8dfc1000, end 8ffff795 ... OK
Loading Device Tree to 8dfb0000, end 8dfc0118 ... OK
This is the Kernel error I get when trying to use the larger initrd.gz:

[ 3.479923] WDT reset called
BP
Root cause of issue:
It looks like ASPEED modified the low level memmove function in /lib/string.c to speed up flash copies. In their code, count is changed to a 4 byte boundary which breaks the back to front copy from memmove_wd.
#ifdef CONFIG_ASPEED_SPI_DMA
if (dest == src)
return dest;
if (
((u32)src >= ASPEED_FMC_CS0_BASE)
&& ((u32)src < (ASPEED_FMC_CS0_BASE + 0x10000000))) {
count = ((count + 3) / 4) * 4;
aspeed_spi_fastcpy((u32)dest, (u32)src, count);
return dest;
}
#endif
I switched memmove_wd() in u-boot/common/image.c to a simpler front to back copy and added the check for CONFIG_WDT and everything works now.
#if defined(CONFIG_HW_WATCHDOG) || defined(CONFIG_WATCHDOG) || defined(CONFIG_WDT)
{
while (len > 0)
{
size_t chunk = (len > chunksz) ? chunksz : len;
WATCHDOG_RESET();
memmove(to, from, chunk);
to += chunk;
from += chunk;
len -= chunk;
}
Another option would be to disable CONFIG_ASPEED_SPI_DMA.
I'm trying to boot Linux on QEMU for RISC-V. I have set up my own toolchain described below:
riscv-gnu-toolchain from git#github.com:riscv/riscv-gnu-toolchain.git
qemu v5.2.0 from https://github.com/qemu/qemu
linux v5.11 from https://github.com/torvalds/linux
busybox v1.33 from https://git.busybox.net/busybox
For Linux and Busybox, I am using basically the default config. I have compiled all of these projects from scratch.
I also created a initramfs image following the instructions here (step 8). I have remembered to make the init script executable.
Finally, I am trying to run with the command
qemu-system-riscv64 -m 4096M -nographic -machine virt -kernel linux/arch/riscv/boot/Image -initrd initramfs.cpio.gz -append "console=ttyS0 init=/init"
The kernel mostly boots fine, but fails to execute /init. The full boot log is below.
The error (-2 == ENOENT) suggests that the file was not found. This makes no sense if the initramfs is used.
I have used a similar command on previous busybox runs with QEMU and it works fine. The provided initramfs image is used as the root/ for the run. I have also tried to replace the /init script with a statically linked ELF binary, but that yields the same results. It seems to me that somehow, the filesystem is not being correctly mounted.
Alternately, I have also tried the instructions at the official tutorial, but the final run command is clearly wrong, as it tries to use the busybox folder as an image (file=busybox).

I think I had that issue in the past. In my case it was because the initramfs was missing the prepended microcode(see more details here: https://wiki.debian.org/initramfs).
I would recommend using buildroot and choose the option that the initramfs is embedded into the kernel Image. Buildroot will prepend that microcode for you.
I installed gem5 on my ubuntu 18.04.5. If I run a generic fs.py ARM architecture then the simulation boots up fine no matter what configuration I use. For example:
./build/ARM/gem5.opt configs/example/fs.py --kernel=/home/ting-bazinga/gem5/fs_imgs/binaries/vmlinux.arm64
--disk-image=/home/ting-bazinga/gem5/fs_imgs/disks/aarch32-ubuntu-natty-headless.img
I followed multiple tutorials to run gem5 in full system mode in ARM bigLITTLE architecture but none succeeded. I tried different disk image files, kernels and bootscript combinations and no luck. Some gives kernel panic errors and some gives:
[ 0.199882] init: hwclock main process (592) terminated with status 1
For example if I use the command(which is provided in http://www.gem5.org/assets/files/ASPLOS2017_gem5_tutorial.pdf):
./build/ARM/gem5.opt configs/example/arm/fs_bigLITTLE.py --kernel=/home/ting-bazinga/gem5/linux-arm-gem5/vmlinux
--cpu-type=atomic --dtb=/home/ting-bazinga/gem5/system/arm/dt/armv8_gem5_v1_big_little_2_4.dtb --disk=/home/ting-bazinga/gem5/fs_imgs/disks/aarch64-ubuntu-trusty-headless.img
then the output is

Can anyone please help me with this? I can't find any configuration that successfully boots up a bigLITTLE arm simulation. Has anyone been able to do this?
Just FYI I found the fs_bigLITTLE.py I downloaded is different from the ones provided by others. Some tutorials use command without the --kernel option but mine says:
fs_bigLITTLE.py: error: argument --kernel is required
I see a problem in your commandline:
./build/ARM/gem5.opt configs/example/arm/fs_bigLITTLE.py \
--kernel=/home/ting-bazinga/gem5/linux-arm-gem5/vmlinux
--cpu-type=atomic \
--dtb=/home/ting-bazinga/gem5/system/arm/dt/armv8_gem5_v1_big_little_2_4.dtb \
--disk=/home/ting-bazinga/gem5/fs_imgs/disks/aarch64-ubuntu-trusty-headless.img
The fs_bigLITTLE is by default using 1 little core and 1 big core, whereas the DTB you are using is assuming 2 big cores and 4 little cores. Removing the --dtb option should just work (relying on DTB autogeneration).
The other option is to align the command line to the dtb (using --big-cpus and --little-cpus option)

I am working with Beaglebone black device
Trying to have my own compiled Kernel and my own rootfs.
I want to avoid using modules in the kernel, and trying to activate the kernel so it will recognize when I plug in FTDI device to the USB Host.
What is the required kernel configuration items for that? Do I need also to change the DTS file?
It looks I do have the driver since I can see the "usb-serial" when I do "cat /proc/devices", it just that I don't get the device detection.
Here is my dmesg - What do I miss?

Thanks

I have resolved this issue (Thanks to TI support):
Use arch/arm/configs/tisdk_am335x-evm_defconfig as the base config - copy it to .config
run "make config"
remove "Enable loadable module support"
Then:
Device Drivers ---> [*] USB support ---> <*> USB Serial Converter support ---> USB FTDI Single Port Serial Driver <*>
Save and Exit, and build the kernel
Use "am335x-boneblack.dts" for DTB
I am using this kernel and dtb with my own rootfs and it identify FTDI device connect
Good Luck
Avner
I have set up a small embedded linux that uses busybox. I am facing a problem of which I'm not sure if its caused by busybox or the kernel.
The problem is, that the init process does not have process ID 1. Heres the output of ps:
1 root 0:26 [swapper/0]
2 root 0:00 [kthreadd]
3 root 0:00 [ksoftirqd/0]
4 root 0:00 [kworker/0:0]
5 root 0:00 [kworker/0:0H]
6 root 0:00 [kworker/u4:0]
7 root 0:00 [rcu_preempt]
8 root 0:00 [rcu_sched]
...
549 root 0:00 {linuxrc} init
...
I guess the other processes before init are all kernel processes. The reason why this is a problem is that orphaned processes are given the parent process ID 1, which should be the init process, but now this swapper process is receiving them all.
I noticed that something is going wrong when I observed a lot of zombie processes.
So somehow either init must be forced to PID 1, or orphaned processes must be assigned to the correct init PID.
Does anyone have an idea how to do that?
Thanks a lot!
Update: Some more information on my setup
The target is an ARM board with a Xilinx Zynq chip. I was using the Xilinx linux Kernel, and compiled busybox myself (v1.20.2).
The command line is:

#sawdust: I don't have a /init file. I think /linuxrc is the first thing that is executed, and that is just a symlink to busybox.
I think I solved the problem. Apparently, adding root=/dev/ram to the boot parameters does the trick. I saw that being recommended somewhere online, but I can't find the link anymore. I'm not entirely sure why this is necessary, but it works :-)
