你好
我在使用 DFU 下载(它在 EVM 板上提供)时在启动阶段遇到问题。
我收到了以下错误:
完成下载 tiboot3.bin 、我无法像那样下载其他固件 tispl.bin\u-boot.img
但是、U-Boot 中不会报告错误
DDR 配置是否不正确? 您是否有必要的 DDR 配置工具?
还是有任何调试方法?
Uboot 输出: U-Boot SPL 2025.01-g00064dce6f98-dirty (Dec 05 2025 - 17:41:31 +0800)SYSFW ABI: 4.0 (firmware rev 0x000b '11.1.5--v11.01.05 (Fancy Rat)')SPL initial stack usage: 13568 bytesTrying to boot from DFU
