Hi, TI Expert,
I`m trying to bring up custom board, and followd acdemy (Porting U-Boot) update DDR configuration and pinmux. Build spl:
# core-secdev-k3 is included in the SDK inside board-support directory.
export TI_SECURE_DEV_PKG=< path to psdk08.06.00.45>/board-support/core-secdev-k3
# Setting the tool chain path
export PATH=/< path to GCC>/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf/bin:$PATH

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- am62ax_evm_r5_usbdfu_defconfig O=$UBOOT_DIR/out/r5
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- O=$UBOOT_DIR/out/r5

cd $K3IG_DIR
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- SOC=am62ax SOC_TYPE=hs-fs SBL=$UBOOT_DIR/out/r5/spl/u-boot-spl.bin SYSFW_DIR=$SYSFW_DIR
Rename tiboot3-am62ax-hs-fs-evm.bin as tiboot3.bin. But after burning tiboot3 with the dfu-util tool, there is no output from the serial port. Could this problem be caused by DDR configuration error?
Then I burning TI EVM board tiboot3.bin to custom board , serial console output:

And TI EVM board optput is

Trying to boot from DFU
Please let me know how to port tiboot3.bin to custom board.
Thanks&Regards.
