I am building an automotive-grade-linux demo image using yocto for raspberrypi3.
I am adding a layer agl-sota for OTA feature. This is where my u-boot breaks.
While booting up according to defconfig CONFIG_ENV_EXT4_DEVICE_AND_PART="0:1" u-boot takes mmc0 which is sd card that can be verified through 'mmc info' and partition 1.
Yet it shows:

What configuration issue is disallowing u-boot to boot the kernel.?
I am using raspberrypi imager for flashing the wic.xz image.

I'm trying to upgrade my u-boot from 2009 to 2020 using buildroot, but when I build the new one it doesn't boot (and I don't have JTAG).
When I load it with imx_usb_loader it works but when I flash it on the Nand, it doesn't boot on it.
As u-boot files, I use mx6sabreauto.c, mx6solo.cfg and mx6sabreauto.h
I don't use SPL or DTS, I only generate u-boot.imx
Boot logs with imx_usb_loader :

It worked when I flashed from the Linux rootfs using these commands :

$ kobs-ng init -x u-boot.imx --search_exponent=1 -v
It seems that the "search-exponent" option did the trick.
I create a linux booting image using TI SDK (am335x) and booting Beaglebone black.
and u-boot boot message is..

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.
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:

I struggle for exceed this error and want to see result like on above. How can I fix this error?
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:

The kernel cannot find the root partition. The kernel command line is set in U-Boot via the environment variable bootargs.
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:

Please check your kernel config and/or bootloader.
Solution:
Add this line to .config:
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.
