I bought a i.MX 93 board(SCH-94611 REV B2)recently and burned the Nxp pre-built yoto bsp image "LF_v6.6.36-2.1.0_images_FRDM_3.0_i.MX93/imx-image-full-imx93frdm.rootfs.wic.zst" to SD card by using UUU utility command in windows11 via usb1_c port in serial downloader mode. Writing was successful.
After that, set Boot Config Switch, SW1[3-0] 0011 to boot from SD card.
As per silk screen,
SW1[3-0] 0010 >> eMMC(default)
0011 >> SD
0001 >> USB
It seems like the kernel fails to mount the root filesystem on the SD card and falls back to eMMC.
Also tried another image file from LF_v6.6.36-2.1.0_images_FRDM_4.0_IMX93 on different SD card and encountered the same problem.
The debug info from Tera Term serial port screen was attached. What am I missing here to boot from SD card?

Thank you. I managed to boot it up from sd card now. Is there any pre-built multimedia Yocto image for FRDM i.MX 93? I also managed to build the image using bitbake in ubuntu and boot successfully. Will proceed to explore more. Thanks again!
Hi @KoThi
i flash the imx-image-full-imx93frdm.rootfs.wic file to the SD card with my i.mx93 frdm board. there is no any problem occurred in the startup period. the flash command as following:
uuu -b sd_all imx-image-full-imx93frdm.rootfs.wic

Hi @KoThi
You can also get the multimedia pre-image in the DEMO Image about imx93 FRDM.
It is imx-image-multimedia-imx93frdm-iwxxx-matter.rootfs.wic file
