工具与软件：
团队成员、您好！
的上使用的器件 AM62xx-LP-EVM &已使用 OSPI NAND 闪存 内存(W35N01JWTBAG) Windows 主机。 我们 正在尝试 通过从 OSPI NAND 闪存中引导和刷写 U-Boot 映像 USB-DFU 正方形数法。
我从下面的链接中获取了参考。
[常见问题解答] SK-AM62：如何在 AM62x-SK E2上使用 USB DFU 进行 eMMC 刷写-处理器论坛-处理器- TI E2E 支持论坛
目前正在执行以下步骤。
要在刷写到 OSPI NAND 闪存之前构建两组映像、 一组用于 USB-DFU 引导 、另一个 设置为刷写到 NAND 闪存 (NAND 闪存引导)。
使用 USB-DFU 引导的第一组映像：
1.使用默认的"am62x_evm_r5_usbdfu_defconfig"和"am62x_evm_a53_defconfig"文件构建引导加载程序映像。
2.从主机 PC 上使用 dfu-util 加载引导加载程序映像 tiboot3.bin、tispl.bin 和 u-boot.img。
以下三个命令用于将 U-Boot 映像从主机传输到目标：
Host> dfu-util.exe -R -A 0 -D tiboot3.bin
host> dfu-util.exe -l
找到 DFU：[0451：6165] devnum=0、cfg=1、intf=0、alt=0、name="tispl.bin"
找到 DFU：[0451：6165] devnum=0、cfg=1、intf=0、alt=1、name="u-boot.img"
Host> dfu-util.exe -R -A 0 -D tispl.bin
host> dfu-util.exe -R -A 1 -D u-boot.img
传输第三个文件后、通过按 EVM UART 控制台中的任意键停止 EVM 自动引导。 此时、u-boot 开始在目标上执行。
在 U-Boot 提示符下、我们将 执行 以下命令。
setenv dfu_alt_info $｛dfu_alt_info_ospi_nand｝
DFU 0和列表
DFU 0 nand 0
然后执行 DFU 0和列表 和 DFU 0 nand 0 这些命令
=> DFU 0 nand 0
DFU 实体配置失败！
(分区表与 dfu_alt_info 不匹配？)
DFU -器件固件升级
=> DFU 0和列表
DFU 实体配置失败！
(分区表与 dfu_alt_info 不匹配？)
DFU -器件固件升级

未找到器件 SPI-NAND0！
请帮助解决我的问题。 我已经附上日志供您参考。
