[参考译文] PROCESSOR-SDK-AM62P：编译 TI boot3 启动错误

尊敬的 Pu Jia：

您是否可以按照说明使用顶级 makefile 来构建 u-boot、并看看这样是否有助于创建 bootimage tiboot3.bin 映像。

https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/latest/exports/docs/linux/Overview/Top_Level_Makefile．html

下载 Processor SDK 安装程序二进制文件后、发出 make u-boot 应该能够在 output directory/r5 文件夹中创建 tiboot3.bin。

请告诉我该怎么做。

此致、

Suren

是的、我使用本指南构建 R5 引导加载程序。 全部制作&&制作 u-boot-R5。 现在我尝试将 defconfig 更改回默认值、img 正在工作、我尝试使用早期启动界面构建 uboot、您能提供指南吗？  

您好：  

明白了、 如果可以在 R5 SPL 中执行操作、早期启动画面是在 A53 SPL 中？

尊敬的 Pu Jia：

您使用 SPL 引导流程并希望在 R5 SPL 中执行启动操作的原因是什么？  在我们的 SBL 引导流程中、我们已经支持 R5 SPL 上的 DSS、这将允许提前启动。

请检查以下链接：

你好, Suren Porwar,

现在、我们计划先使用 Falcon 模式启动 EVM、然后是 MCU SDK、

我想在 MCU_R5_NORTOS 中添加 bmp 启动画面吗？

尊敬的 Pu Jia：

请按照 MCU+SDK 文档中提供的说明进行操作。

https://software-dl.ti.com/mcu-plus-sdk/esd/AM62PX/11_01_00_16/exports/docs/api_guide_am62px/EXAMPLES_DRIVERS_DSS_DISPLAY_SHARE.html

如果您有任何问题、请告诉我。

此致、

Suren

您好、Suren Porwar

演示运行正常、但我有一些问题：

1.演示应用程序是构建 stage2 SBL 加载器吗?

2、图标闪烁前仍有闪屏标志,何时以及如何加载闪屏?

3.闪存至 eMMC 时,无法加载操作系统内核。 有一些奇怪的是从 eMMC 加载在第 1 阶段、但加载第 2 阶段在 OSPI 中、然后我不知道它是如何运行的

您好、

您是否尝试使用双引导介质 (OSPI 和 eMMC) 运行？ 或仅 eMMC。

此致、

Suren

您好团队

否、现在我尝试更改了 SysConfig 中的 demo dss_display_share 设置、以将所有启动设置为 eMMC：

然后启动等待

您好、

您运行的是 Linux 还是 QNX？

此致、

Suren

尊敬的 TI 团队

QNX、  

我已经解决了这个问题、我将启动时的代码更改为初始化 EMMC、然后引导就可以了。
