[参考译文] LP-AM261：工业通信双核示例

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1556333/lp-am261-industrial-comms-dual-core-example

工具/软件：

您好：

我想知道是否有任何将 AM2612 的两个内核与工业通信 SDK 一起使用的示例。 我们希望能够在一个核心中运行现场总线堆栈、并 将另一个核心用于我们的应用、该应用将处理数据、然后将其发送到现场总线堆栈。 我尝试了创建一个示例工程、我的团队成员也可以导入到 CCS 中作为起点、但在正确编译时遇到了问题、我假设我没有正确设置 sys config 文件、因为我不知道如何修改这些文件以使用双核、并尝试复制我在 MCU+ SDK 中从双核示例看到的内容。 具体来说、当我尝试将工程导入 CCS20 并进行编译时、会收到以下错误消息。 我认为我遇到的问题主要是不知道如何正确修改系统配置文件、尤其是内存区域。

我附上了一个尝试导入 CCS20 的工程的 zip 文件。
