Beaglebone black uImage boot issues - linux-kernel

I am trying to boot the beaglebone black using the uImage file that I created using the mkimage command. There is a emmc to sd image flasher package available online which has a uImage in it and also other required files (https://elinux.org/BeagleBone_Black_Extracting_eMMC_contents), I followed this website and created a flasher card of the uImage that I made using mkimage utility.
I am getting the following error during boot from SD card having that uImage:

I create a linux booting image using TI SDK (am335x) and booting Beaglebone black.

u-boot and linux kernel work properly.
Do I need solve this warning ?.
Maybe your u-boot script didn't switch to the right partition of MMC before started reading uEnv.txt or so. This is okay if you are fine with booting behavior. These files contain things like do you want to enable HDMI, or console, etc. But the same could be done directly in u-boot env.

Allwinner A13 hang on boot and return "SPL:Unsupported Boot Device!" error

I am new in here and I am sorry my bad English.
I have OLinuXino A13 board. I endeavor kernel and boot events. So I try boot OLinuxino-A13 via spiflash(in FEL mode). I connected board to my PC(USB OTG). I Sending commands from my computer for writing to spiflash. And differently I build second connect with usb-ttl. So I can see opening writing of board with CuteCom program from my PC. And I use sunxi-tools for write to spiflash of my board.
And I did this:
I compiled kernel and I created u-boot-sunxi-with-spl.bin file. After I entered FEL mode and I wrote this file to on my board with ./sunxi-fel spiflash-write 0 /path/u-boot-sunxi-with-spl.bin. When I use boot my board from PC with ./sunxi-fel uboot /path/u-boot-sunxi-with-spl.bin, my board start and it work for find to sd card. Result this:

Qemu Freescale i.MX6 DualLite SABRE : root filesystem does not mount

Goal: emulate the "sabrelite : Freescale i.MX6 Quad SABRE Lite Board (Cortex A9)" that Qemu specifically supports (doing 'qemu-system-arm -M ?' it shows up).
Qemu ver: 2.10.1 (host: fedora-27).
I have successfully cross-compiled and built a 4.1.46 Linux kernel (used the imx_v6_v7_defconfig config file) as well as a simple "skeleton" root filesystem (busybox-based). (FYI, I have a similar working setup for the ARM Cortex-A9 Versatile Express platform - I do this using my own home-spun embedded Linux system called SEALS).
Looking at the U-Boot config file used by similar boards, I figured to use 'root=/dev/mmcblk0p0' as the root= param for the kernel.
So, to try it out I then run qemu as follows (pl scroll horizontally as well to see):
qemu-system-arm -m 512 -M sabrelite -kernel zImage -drive file=rfs.img,format=raw -append "console=ttymxc0 rootfstype=ext4 root=/dev/mmcblk0p0 rw rootwait init=/sbin/init " -nographic -dtb imx6dl-sabresd.dtb

[ 3.007698] Waiting for root device /dev/mmcblk0p0...
Keeps waiting forever here ...
I understand that, on an actual physical board, one would have to "format" or partition the MMC (or SD) card, and have u-boot load up the kernel and rootfs into RAM. But am currently interested in getting the IMX6 working on Qemu...
So, my actual question: how can I get the root filesystem mounted and operational on Qemu?
Any help appreciated! TIA,
There are two problems here. Firstly, your command line isn't actually creating an SD card: the -drive option creates a drive object but doesn't try to plug it in anywhere (because the sabrelite board doesn't define a "default kind of block drive"). To actually plug in the drive to an emulated sd card you need
-drive file=yourfile.img,format=raw,id=mycard -device sd-card,drive=mycard
Secondly, there are bugs in QEMU's current imx6 sd controller emulation, because if you do that then the guest kernel continuously prints
[ 28.971663] mmc1: Timeout waiting for hardware interrupt.
[ 28.973619] mmc1: error -110 whilst initialising SD card
...so it has found the emulated card but isn't getting an interrupt it expects.
These can be fixed by a patch currently on the qemu-devel mailing lists and going through code review: http://patchwork.ozlabs.org/patch/834805/ plus a simple change to hw/arm/fsl-imx6.c to make it create TYPE_IMX_USDHC devices rather than TYPE_SYSBUS_SDHCI. (Basically the imx6's SD controller isn't a completely standard compatible sdhci controller but what we were creating in the QEMU model was the plain variety.)
If you do all that then you can boot a kernel that can see the mmc card:
[ 8.878283] mmc1: new SD card at address 4567
[ 8.910566] mmcblk0: mmc1:4567 QEMU! 256 MiB
With a little luck we'll be able to have this fixed in the 2.12 release of QEMU, which will be out in some time in spring 2018.
Edit as of 9 Mar 2018 -- the relevant fixes are now in QEMU master (commits fd1e5c81796, df2a5cf4c8) and will be in 2.12.

Linux kernel for A20 cpu stuck at 'Starting kernel'

Linux kernel version: 4.1.8
board:cubietruck with A20 CPU.
compiled platform: os x 10.5.5
I do as follows:
First I use sunxi_defconfig as the default configuration, but 'byte_swap.h' not found error occurred. Then I use a sun7i_defconfig which offered by cubieboard, and then make -j4 ARCH=arm CROSS_COMPILE=arm-none-eabi- zImage,make -j4 ARCH=arm CROSS_COMPILE=arm-none-eabi- dtbs.
Then I burn the Uboot and the spl to the SDCard and make to partitions: one for boot and one for root file system. I put the zImage, script.bin and the dtb file on the boot partition.
Then I create boot.cmd as below:
fatload mmc 0 0x46000000 zImage
fatload mmc 0 0x49000000 sun7i-a20-cubietruck.dtb
setenv bootargs console=ttyS0,115200 earlyprintk root=/dev/mmcblk0p2 rootwait panic=10 ${extra}
bootz 0x46000000 - 0x49000000
and then mkimage -C none -A arm -T script -d boot.cmd boot.scr.
so there's three files on the boot partition:
boot.scr
script.bin
sun7i-a20-cubietruck.dtb
zImage
the Uboot works fine.(At least I think), here is the output

AT91SAM9263ek booting Linux with Device Tree failed

I have problem booting Linux 3.16.1. I have compiled sources from http://www.kernel.org with at91sam9263_defconfig.
I have added Flattened Device Tree support in Boot options.
Followin tips suggested in this (https://www.slideshare.net/softpapa/device-tree-support-on-arm-linux-8930303) presentation to turn on Support device tree in /proc but i don't have that option in menuconfig.
I have U-Boot bootloader version 2014.10rc2 which supports device tree.
I have generated dtb from script shipped with kernel:
make at91sam9263ek.dtb
And now i'm getting this error:

CONFIG_MACH_AT91SAM9_DT=y
The correct configuration for this board when using device tree is at91_dt_defconfig.
However, I am quite surprised to see someone trying to use such an old kernel. This board is fully supported upstream. Why don't you use v5.3? If this doesn't work, please report any bug, we will be happy to help correct them.
