Hello NXP experts,
I am following "UG10164, i.MX Yocto Project User's Guide, Rev. LF6.12.3_1.0.0 — 31 March 2025".
I have to configure u-boot with
- uboot_config_imx93evk="sd fspi"
as showed in chapter "5.5 U-Boot configuration".
As suggested i runned the command:
- echo "UBOOT_CONFIG = \"sd fspi\"" >> conf/local.conf
and after i runned
- bitbake core-image-minimal.
An error is raised during the bitbake:
ERROR: Nothing PROVIDES 'virtual/bootloader' (but /home/imx-yocto-bsp/sources/poky/meta/recipes-core/images/core-image-minimal.bb DEPENDS on or otherwise requires it)

thanks for the support!
HI @il_ciancio!
By default is not possible you should do some modifications and we can't validate the image due to the evk board doesn't have fspi installed.
Best Regards!

Ciao @Chavira.
I have a question, maybe I am misunderstanding something.
I am working with a custom board without eMMC or SD card and It has only a SPI NOR FLASH, the goal is to boot starting from data inside the SPI memory on target IMX93.
There is also this ticket: all(bootloader, device tree, Linux kernel, rootfs)
It is made a custom UUU script in order to flash data in SPI memory:
- uboot;
- dtb;
- kernel;
- rootfs;
the flash goes well because it is checked raw data read from spi memory.
After the boot, It is read data from SPI and putted in ram (like a bridge), some env vars are setted and after with the command booti:
- booti ${loadaddr} ${initrd_addr} ${fdt_addr}
the kernel should boot.
Why did you write "then use the rootfs flashed in eMMC or SD card."? Is it mandatory that rootfs must be in sd/emmc?
I hope that I am clear.
Thanks a lot!
Hi @il_ciancio!
You can't flash the rootfs in the flash memory.
You can boot from fspi and then use the rootfs flashed in eMMC or SD card.
Best Regards!

Hi @Chavira ,
congratulation, great job!
Now the bitabake is finished and i have u-boot*fspi files in my deploy directory.
Just for clarification, which are the kernel/rootfs image "compatible" with fspi? It is always the *.wic file?
thanks a lot and again great work!
Hi @il_ciancio!
I found the problem!
For some reason the fspi configuration is not included.
You have to add the next lines in the imx93-11x11-lpddr4x-evk.conf file.
UBOOT_CONFIG[fspi] = "${UBOOT_CONFIG_BASENAME}_defconfig"
IMXBOOT_TARGETS_FSPI = "flash_singleboot_flexspi"
IMXBOOT_TARGETS = "${@bb.utils.contains('UBOOT_CONFIG', 'fspi', '${IMXBOOT_TARGETS_FSPI}', 'flash_singleboot', d)}"
after that you can maintain the line UBOOT_CONFIG = "sd fspi" in local.conf file to deploy both images.
Best Regards!
Chavira
with UBOOT_CONFIG ??= "sd fspi" the bitbake is finished, but in the output folder there is *.wic file but there isn't a Flex-SPI u-boot binary image.
Is there something else?
How is the result of your build?
Hi @il_ciancio!
Thank you for contacting NXP Support!
I am compiling now.
Try changing UBOOT_CONFIG = "sd fspi" to UBOOT_CONFIG ??= "sd fspi" in the local.conf file.
Best Regards!
