工具/软件：

您好、

我的客户希望使用 OSPI 引导来引导双核。他们尝试了以下步骤,但到目前为止没有成功。
您能回顾一下这些步骤并提供反馈吗？

步骤 1：build SDK empty 示例“empty_am263px-cc_system_nortos"。“。
步骤 2：在 Uniflash 中、将“empty_system.appimage"或“或“empty_system.mcelf"配置“配置为应用程序映像。
步骤 3：客户尝试使用“sbl_ospi_moreelf_am263px-cc_r5fss0-0_nortos_ti-arm-clang"作为“作为 SBL、但生成了链接器错误。
因此、它们改用了“sbl_ospi_am263px-cc_r5fss0-0_nortos_ti-arm-clang"。“。

当“sbl_ospi_morple_elf_am263px-cc_r5fss0-0_nortos_ti-arm-clang"用作“用作 SBL 时、会生成链接器错误。

**** Build Finished ****

步骤 4：刷新 OSPI 存储器
步骤 5：将引导模式更改为 OSPI 引导并对电路板进行下电上电。以下是端子输出。
