I am using Intel Joule 570x board for reference which has 64-bit x86 architecture.
I am using GRUB2 as the bootloader and mainline kernel 4.9. I built the kernel, also busybox rootfs and then tested them on qemu and I can boot to shell.
Now I put the kernel bzImage, GRUB and rootfs onto the USB. I have created first partition as FAT and put bzImage and GRUB files there. I created second partition as ext4 and put rootfs files there. Then I plugged it to the development board.
This is my GRUB menuentry :
menuentry "dev kernel" {
set root=(hd0,msdos2)
linux (hd0,msdos1)/bzImage root=/dev/sda console=ttyS2,115200n8 console=tty0
}
The kernel throws error :
VFS: Cannot open root device "sda" or unknown-block(0,0): error -6
Can anyone please help. My USB is also getting detected and I have built all the filesystems (fat,ext4,etc.) into the kernel. The board also has eMMC inbuilt storage and SD card which are also getting detected.
Here are complete boot logs :

EDIT
One strage behaviour I have noticed, if I pass kernel parameter from GRUB2 as /dev/sdb, then the kernel shows sda1 and sda2 as the available partitions, with same error.
Kernel Config file : https://pastebin.com/twi9Deis
The solution is to add "rootwait" to the kernel commandline. The USB pendrive needs a little time to be recognized so the kernel need to wait for it.

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 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?

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 am a noob to building custom linux OSes for embedded boards - so please ignore my ignorance.
I have a board called NanoPi NEO that has custom Debian linux. Now the board comes with a .img file that can be flashed on to an SD card and plugged into the slot and the board boots from the card.
Now I am trying to build my own Custom linux and flash to the SD card. I have been through the forums and manuals and managed to get this far.
Problem
I understand that there are three components to a custom linux build
boot0 - The thing that loads the BootLoader
U-Boot - One of the many BootLoaders. (The project uses this).
Rootfs - The filesystem and everything else.
The board manufacturer's website gave these instructions for building custom os. I followed those instructions and did everything including proper partitioning of the SD card (with free space in front for boot0, boot partition with uImage and Script.bin, and partition for rootfs)
The problem is that the board loads the Kernel on boot but doesn't mount the filesystem and prove a user prompt.
This is the Dmesg output.

So I guess the issue is with the rootfs not being detected and mounted correctly. Please guide me on this.
I'm pretty sure the problem is that the linux doesn't activate a console on uart.
Take a look at kernel log:
[ 0.000000] Kernel command line: console=ttyS0,115200 console=tty0 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait init=/sbin/init
As noted in http://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/configure-kernel.html:
When multiple consoles are listed output is sent to all consoles and input is taken from the last listed console. The last console is the one Linux uses as the /dev/console device.
So try making console=ttyS0,115200 being the last (or the only) console option by tuning bootargs u-boot environment variable.
To check this suggestion, just "Hit any key to stop autoboot", then use printenv to inspect default bootargs content, run setenv bootargs ... ... ... and finally, run bootd. However, be sure to inspect bootcmd and what does it call, because one of those things may invoke setenv bootargs during bootcmd execution and overwrite your manual option.
P.S. init=/sbin/init may be omitted.
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:
ramdisk_size=65536 console=ttyPS0,115200 earlyprintk
Here are the bootlogs up to the moment that the init script is started:

#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 :-)
