器件型号：SK-AM62P-LP 主题： AM62P 中讨论的其他器件
工具/软件：
您好、专家、
我收到了评估板 SK-AM62P-LP。 AM62P 可能是我们下一代器件的理想 SoC。
我们的引导过程在很大程度上取决于通过 USB 连接的 DFU。 到目前为止、我还无法让它正常工作。 我放置 SW4和 SW5
进入 USB 引导模式(SW5：00000000 SW4：11001010)。 为电路板上电时、会得到：
bomellberg@bosse-buildcom:~/se3linux/yocto-base/build/tmp/deploy/images/am62pxx-evm$ sudo dfu-util -l dfu-util 0.9 Copyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc.

然后发送我使用 Yocto 构建系统构建的第一个引导文件 tiboot3.bín：
bomellberg@bosse-buildcom:~/se3linux/yocto-base/build/tmp/deploy/images/am62pxx-evm$ sudo dfu-util -a bootloader -D tiboot3-am62px-hs-fs-evm-am62pxx-evm-k3r5-2024.04+git-r0.bin dfu-util 0.9 Copyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc.

之后、我没有收到预期的 sysfw.itb:申请

我站在 U-Boot 2024.04分支的顶部： bomellberg@bosse-buildcom:~/se3linux/ti-u-boot$ git stOn branch ti-u-boot-2024.04
我在 am62px_evm_a53_defconfig 和 am62px_evm_r5_defconfig 中添加了以下行：
include <configs/am62x_a53_usbdfu.config>和
include <configs/am62x_r5_usbdfu.config>
UART 调试会显示以下内容：
U-Boot SPL 2024.04-ti-g29d0c23d67ee (Jun 02 2025 - 11:23:30 +0200) SYSFW ABI: 4.0 (firmware rev 0x000b '11.0.7--v11.00.07 (Fancy Rat)') SPL initial stack usage: 17072 bytes SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
我也尝试使用预编译文件、结果相同。
将文件放在 SD 卡上工作正常。 才是问题所在的是 DFU 引导过程。
此致、
