[参考译文] PROCESSOR-SDK-J722S：如何在 SD 引导模式下运行基于 RTOS SDK 构建的 MCU 程序？

工具/软件：

尊敬的 TI 专家：

我想从 SD 卡运行编译后的 mcub10 程序。 是否有任何有关此流程的文档？
我的硬件是 J722S-EVM 板、使用最新的 J722S V11 RTOS/Linux SDK

1.目前,我使用预编译的固件创建了 SD 卡, Linux 正在正确启动。
2.按照与 J721E V9 类似的过程、我编译了“cu_plus_sdk_j722s_11_00_00_12/examples/drivers/ipc/ipc_rpmsg_echo_linux"工程“工程并获取 ipc_rpmsg_echo_linux.release.out 文件

3.将其置于 sdk_builder/makerules/makefile_uboot.mak 内的 vision_apps_linux_dm 变量中。 然后、使用 Linux SDK 编译 tispl.bin、我将其替换在 SD 卡的引导分区中（其他文件保持不变）。

给电路板上电时、Linux 串行控制台无法正常工作、显示以下错误：

我的 tispl.bin

e2e.ti.com/.../tispl.bin.txt

我应该如何修改它？ 谢谢你。
