AM6442: Uboot cannot find device tree

Jakub Grad

Part Number: AM6442

Hello

I am using Yocto to build an image for AM6442-SK board. On AM6442-SK the image is running fine, but on TMDS64GPEVM there is some issue at booting...

Error message:

It looks like U-Boot cannot find device tree k3-am642-evm.dtb, but why?

KERNEL_DEVICETREE yocto variable contains:

" ti/k3-am642-evm.dtb ti/k3-am642-sk.dtb ti/k3-am642-evm-icssg1-dualemac.dtbo ti/k3-am642-evm-nand.dtbo ti/tpm-slb9670-overlay.dtbo ti/spidev-overlay.dtbo ti/gpios-hardware-test-overlay.dtbo ti/cmdline.dtbo"

So proper device tree is present.

Any hints?

Hello Jakub,
I'm attaching two log files I captured on AM64x EVM with SDK 8.4 release.
www.ti.com/.../08.04.01.04
#1. am64_sdk8.4_gp_sr1_env.txt: the default log file
#2. am64_sdk8.4_gp_sr1_dtbo_nand.txt: load the DTBO "k3-am642-evm-nand.dtbo" for NAND daugter card
In #1 log file:
- <name_overlays> is NOT defined => The <*.dtbo> files are NOT loaded by default
- The matching board dtb <k3-am642-evm.dtb> is loaded as shown in the following lines from the log file
55885 k3-am642-evm.dtb
...
55885 bytes read in 6 ms (8.9 MiB/s)

In #2 log file:
- I added <name_overlays> as listed below
=> setenv name_overlays k3-am642-evm-nand.dtbo
- In addition to the matching board dtb <k3-am642-evm.dtb>, <k3-am642-evm-nand.dtbo> is loaded as shown in the following lines
2979 k3-am642-evm-nand.dtbo
...
2979 bytes read in 3 ms (969.7 KiB/s)
- NAND device on the daughter card is probed in the kernel boot log

I figure it out that the problem was with device tree overlays. These overlays are not compatible with EVM board. How can I make Yocto distinguish specific overlay depends on hardware? In Yocto machine is defined as "am64xx-evm" and it handles both AM6442-SK and TMDS64GPEVM boards.

Hello Jakub,
When I built for TI AM64x boards (AM64x EVM & AM64x SK) from TI Linux kernel tree, the following kerenl dtb/dtbo are built
https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/Makefile?h=cicd.2022.10.25.19.06.00#n48

dtb-$(CONFIG_ARCH_K3) += k3-am642-evm.dtb
dtb-$(CONFIG_ARCH_K3) += k3-am642-evm-icssg1-dualemac.dtbo
dtb-$(CONFIG_ARCH_K3) += k3-am642-evm-icssg1-dualemac-mii.dtbo
dtb-$(CONFIG_ARCH_K3) += k3-am642-evm-nand.dtbo
dtb-$(CONFIG_ARCH_K3) += k3-am642-sk.dtb

These dtb/dtbo are installed in "rootfs/boot/" folder, and one of matching board dtb is loaded by u-boot along with kernel.
- k3-am642-evm.dtb for TI AM64x EVM board
- k3-am642-sk.dtb for TI AM64x SK board
Additionally dtbo is loadable if necessary as noted in my last reply with "k3-am642-evm-nand.dtbo" as an example for the NAND daughtercard.
Best,
-Hong
