若要启动处理器，SOP 引脚需要根据从哪里启动而正确设置。开关 SW1 在复位时通过 U15 连接，并为处理器提供相关配置。

由于该参考设计使用的闪存比 AM261 EVM 和所有软件示例更大，因此需要修改 SDK 中的引导加载程序相关文件，以便 syscfg 生成的 ti_board_open_close.c 文件如下所示。该配置允许以高达 133MHz 的速度在高速 OSPI 模式下引导。

该处理器包含两个实现 IO-Link 及工业以太网的 ICSS。所有八个 IO-Link 端口都由一个 ICSS 处理。该以太网与第二个处理器接合。有关 AM261 可用堆栈的详细信息，请参阅工业通信 SDK 发行说明。
