I have built an image for the TQ Systems STKa8x Evaluation board with an i.MX8 QuadMax using the yocto project. The resulting image does not boot on the device. Can anyone help me interpret the warnings and errors occuring in the serial console output when trying to boot?
I think the the machine configuration might be wrong? The device hardware is ok, becaus the device boots using the included sd card.
Did you flash your Yocto image in your emmc or SDcard ? Here it seams that there is no partition table in your emmc which is normally embedded inside Linux image. It is more likely that the flash did not succeed.
Plus you can see warning from u-boot that he cannot load the device tree. Check your repository build/tmp/deploy/image/machine/*.dtb
You should also check if your linux image and device tree is flashed in the correct address.
Solved: The problem was caused by the SD card. I have used this SD card https://de.transcend-info.com/embedded/product/embedded-memory-cards/usd230i. Using another one solved my problem.

I had built a Yocto image from honister branch. I created a bootable USB drive and flashed my image into it. Whenever I wanted to boot into the USB drive, I am always given 3 different choice:
boot, install, Reboot Into Firmware Interface
This is a picture of what I see when I boot:
My question are there any way I can make my yocto image in my USB drive to boot straight into the OS without giving any of those options?
Do I need to make the needed configuration in my already built image or I need to rebuild the image after changing some configuration in my poky or any other meta layers?
Thanks,
Hari
I just started working with a Beagle Bone Blue and I have installed the necessary drivers however when I go to http://192.168.7.2/, it say the site cannot be reached because it took too long to respond. I would really appreciate it if someone would help be. Thanks!
I think the kernel image you are using in BeagleBone Blue must be properly booted in the board or if you are using eMMC0 for booting the board,
Check the kernel logs of booting using minicom in Linux or putty/Terraterm in Windows.
Also, check if there is one folder creating as BeagleBone(Getting Started) in Windows after proper booting done.
If you are using Linux, check the same type of folder and verify the internet connectivity.
Try to use new kernel image available from https://beagleboard.org/latest-images
Boot it using sd Card and flash it on the board.
Then, try 192.168.7.2 in the browser.
It will be working if you follow the proper steps.
I hope it helps.
I followed this tutorial to boot the ULTRA 96 :
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841783/Building+Xen+Hypervisor+with+Petalinux+2018.1
I'm using petalinux-v2018.2-final and xilinx-ultra96-reva-v2018.2-final.bsp
I built the project myself then copied necessary files into the SD card (BOOT.bin,xen.ub.system.dtb,image,rootfs.cpio.gz.u-boot) int the boot partition and the rootfs files(extracted from rootfs.cpio) into the root partition of the SD card. I even tried copying the same files from the pre-built images in the project but there is no response at all from the card when I enter sudo screen ... or even when I tried with trace32.
please help I'm stuck here and thank you for your time!
Update:
when I copied the prebuilt images and connected the board to a screen via display port, the system boots and opens a Linux kernel based system but when i searched if it's a Dom 0 for the xen i didn"t find anything( when I entered dmesg | grep xen it showed nothing). My problem is if this system is the Dom 0 for xen or it's simply a linux image on my board and thank you :)
I have an embedded system running Linux, with many peripheral devices connected.
There are some storage devices connected too. Currently, we do not have any diagnostics tool to check the state of devices on the system.
what I want to do with this diagnostics tool is something like:
After connecting to my embedded system either via USB or network port, I want to be able to browse storage media ( in read only mod ), and may be later in future extend this to check the status of other devices running.
With this question, I am seeking guidance of expert people who have faced similar problem and were successfully implement a solution.
I am not looking for a solution but a likely approach.
thanks
one approach is that (it totally depends on your embedded board)
if your board supports booting from the usb, you can modify your bootloader code to boot linux initrd image from the usb, if usb is plugged in your board, otherwise noraml booting procedure.
you can write one c diagnostic utility to check the status of different peripherals and generate the report on the usbdisk
create Linux initrd image for your board with modified rcS file to mount the usb in Linux and start the utility while boot up, copy the utility in bin folder of your rootfilesystem.
now when you power-on your board with usb connected, your testing software will boot and test the peripherals otherwise your normal software will boot.
hope this helps!!
I've one craneboard.it has sdcard which has u-boot v2013.04.I want to load kernel images via Network(using ethernet interface) into SD card.
What steps i should take for do this.
Please help.
Problem solved.Actually there was problem related to enabling some MACRO.
Include MACRO related to NET and CONFIG_MACH_DAVINCI_DA850_EVM in am3517.h file.
