STM32MP135 Uboot libfdt fdt_check_header(): FDT_ERR_BADMAGIC

[jhi]

I'm trying to boot from SD-card and u-boot doesn't seem to find device tree. I have built my system with buildroot (bootlin st/2023.02.2) overriding the sources for tf-a, u-boot, op-tee and kernel, to be able to boot at least to u-boot (I did write another posts of my problems).

The files in SD-card

boot
├── extlinux
│   └── extlinux.conf
├── myb-stm32mp135x-512m.dtb
└── zImage

extlinux.conf

label myb-stm32mp135x-512m-buildroot
  kernel /boot/zImage
  devicetree /boot/myb-stm32mp135x-512m.dtb
  append root=/dev/mmcblk0p5 rootwait rw console=ttySTM0,115200

genimage

image sdcard.img {
	hdimage {
		partition-table-type = "gpt"
	}

	partition fsbl1 {
		image = "%ATFBIN%"
	}

	partition fsbl2 {
		image = "%ATFBIN%"
	}

	partition fip {
		image = "fip.bin"
	}

	partition u-boot-env {
		size = 2M
	}

	partition rootfs {
		image = "rootfs.ext4"
		bootable = "yes"
	}
}

So any ideas why it doesn't work?

Thanks a lot, Patrick. This worked for formatting the SD card. But I had some changed configuration, because of that It could not boot to linux. I changed my configuration, and from u-boot console I gave some boot command and after that, and it booted through Linux. Thanks again.
