FreeRTOS+Linux
出于某些原因、我们希望 ATF 直接引导 uboot、这是否可行？ 如果是、我们应该如何处理？

您好！
AM68上的参考示例：
您必须在 TDA4VM 上执行非常类似的操作。
此致、
基尔西
你(们)好
1.我们当前的引导流程是 R5 SBL -> ATF -> OPTEE -> uboot-spl -> uboot -> Linux、然后我们要将其更改为 R5 SBL -> ATF -> OPTEE -> uboot -> Linux。
2. 从上面的参考示例中,我们发现 ATF 没有做任何改变,这是可以的吗? 我们 在 SBL 中将 uboot 加载到0x800000、然后默认 ATF 会直接引导 uboot？
3. 我们发现上面的例子只改变了 Linux,但我们通过 uboot 加载了 Linux,所以我觉得我们不需要做任何改变,是吗?
4. 我们试图移除 uboot-spl、SBL 启动似乎正常、但 A72在启动至 OPTEE 后卡住。 日志如下所示
R5 SBL

您好！
[报价 userid="533595" url="~/support/processors-group/processors/f/processors-forum/1462880/tda4vm-how-does-atf-directly-boot-uboot/5613730 #5613730"]我们尝试删除 uboot-spl、SBL 引导似乎没问题、但 A72在引导至 OPTEE 后卡住。 按如下方式记录在以下位置加载 tisPL 中的 SPL 也称为 A72 spl 0x80080000
默认情况下 U-Boot 设置为 AT 080800000
您是否已更改 ATF 中的 plat/ti/k3/platform.mk - board-support/trusted-firmware-a-2.11+git
Preloaded_BL33_BASE？= 0x80080000
基本而言、ATF 假设下一个引导映像是在0x80080000处加载的、但 U-Boot 是在080800000处加载的。
