你(们)好

我尝试在 u-boot 之前启动远程进程以运行 MCU-R5应用程序。

(参考网页：https://e2e.ti.com/support/processors-group/processors/f/processors-forum/903161/compiler-processor-sdk-dra8x-tda4x-compiler-processor-sdk-dra8x-tda4x)

MCU-R5应用程序(@MCU 域)用于与主域中的 a72进行 SPI 通信。

但看起来，rproc 不起作用。

首先，从 MMC 加载环境后，在 ARM64内核上启动 ATF。

所以我在 u-boot 命令上执行了'etenv dorproboot 1'和'aveenv'。

重置后，没有任何变化。在 VISION _APPS_Build _FLAS.MaK 中将“build_CPU1_0”设置为“是”后，我就完成了构建。

我应该如何配置启用 rproc 的任何附加功能？

您好，Yongsig，

IIUC，您正在尝试启动自己的 MCU1_0固件映像，对吗？

MCU1_0固件必须与 A72 SPL 二进制文件结合使用，并内置于 tifl.bin 中。如果尚未重建 U-Boot A72二进制文件，则仍在运行旧的 MCU1_0固件。

这仅是 MCU1_0的要求，因为它是一个特殊的处理器，涉及到启动过程。

所有其它处理器都可以在 U-Boot 提示符下进行早期引导。
