器件型号：AM62A7 主题中讨论的其他器件：SysConfig
尊敬的团队：
我们需要在终端评估 MCU r5f 上的 i2c1从站、
I2C 1从器件(MCU r5f 侧)、I2C 2主器件(A72 Linux 侧)
我们已经回顾了链路、可以在 MCU R5f 中实现 I2C 从器件
AM62A7：AM62A7主域 I2C 控制器支持从模式？-处理器论坛-处理器- TI E2E 支持论坛

已在 A72上识别了从器件、存在一些问题、 在 A72 i2c2中找到了新地址、但在尝试读取或写入时、发生了超时类打印
Pinmux 是正确的

如何实现中断模式从器件和主器件对从器件的读写
您能帮我检查我的代码是否有问题吗
或者
您能提供一个用于实现从模式的演示程序吗
