AM625尝试添加自己的工程，在uboot里的am62x_evm_a53_config中将CONFIG_DEFAULT_DEVICE_TREE指定为我们内部工程名，编译出来的tispl.bin无法进入dfu烧录模式，请问这个怎么更改。

请问是自己的板子么？使用的是哪个版本的processor SDK? 用原来的设备树名可以进入烧录模式么？

是自己产品的板子，processor SDK：linux 08.03.00.005; 用原设备树可以进入烧录模式
,
Shine：
谢谢，能否发一下您板子的设备树？

附件为我编译的dtb文件，发现a53/spl/dts目录下的dtb文件比原始的要小。

请看下面工程师的回复。For building u-boot for USB-DFU boot mode on AM62x-SK E2 board, the "am62x_evm_r5_usbdfu_defconfig" needs to be used for building R5-SPL (tiboot3.bin). The e2e post is on full Linux eMMC flashing via USB-DFU mode on AM62x-SK E2 for your reference. SK-AM62: Fail to load rootfs using usb dfu – Processors forum – Processors – TI E2E support forums

目前我就更改了am62x_evm_a53_config，将CONFIG_DEFAULT_DEVICE_TREE指定为“k3-am625-r5-sk-dc2221”, 其他都没变；我感觉还是uboot 哪里没配置正确；能帮忙用你们的板子测试一下吗？
