[参考译文] AM62P：如何在安全重新启动时为 Linux 生成映像并进行引导？

您好：

Processor SDK 没有加密引导支持。

MCU+ SDK 具有相应的支持功能、可以使用"devconfig/devconfig.mak"文件中定义的标志"ENC_ENABLE"和"ENC_SBL_ENABLE"来启用这些支持功能。

此致、

Prashant

您好、

ti/mcu_plus_sdk_am62px_10_00_00_14/tools/boot/linuxAppimageGen/board/am62px-sk/linux.appimage.hs ->linux_a53_image   

有我怎么做的。 这种行为合适吗？  

我是否需要刷写所有映像才能在 hs 器件上启动？

我认为是的。 引导应该成功。

以下是我的 tiboot3.bin 中的日志(我添加了一些日志)。

您能告诉我们可能出了什么问题吗？

Unknown 说：

日志中没有任何内容可以提供任何见解。

您能否检查"App_loadImages"函数内执行到底失败的位置？

谢谢！

您能否检查在作为 Bootloader_parseMultiCoreAppImage 一部分执行的函数"Bootloader_socAuthImage"中执行是否失败 ：

github.com/.../bootloader.c

如果在此阶段确实失败、则可能没有不同内核的正确签名的映像。

这是 TI 官方电路板中相同的 SD 卡输出。  

您是否可以一次尝试以下图像：

e2e.ti.com/.../appimages.zip

我共享的映像是使用相同的 MAK 配置构建的、只是"ENC_ENABLE"设置为"NO" 您也可以尝试同样的方法吗？

如果您的映像仍然无法启动、请将其共享给我以评估差异。

Unknown 说：

现在、我想了解为什么 我的客户主板和 TI 官方主板中相同的启动 SD 卡显示方式不同。

我没有得到这个。

您说过将 ENC_ENABLED 设置为 NO 后、您生成的映像将成功引导。 然后、在哪种配置下、您在定制电路板上仍然会出现故障？

是的、您给我和我的映像在 ENC_ENABLED 后重建为 NO、以在 TI 的官方电路板上引导。但两者都以相同的方式在我的客户电路板上失败。

你好、Prashant

解决 DDR 问题后,我遇到了一些新的问题.

第一个输出在客户电路板上。 第二个来自官方委员会。

你能告诉我这可能的原因吗?

请参阅以下指南中提到的权变措施是否有帮助：
