你(们)好
这涉及 EtherCAT 从站-工业协议到基于 AM6421 SOC 的定制电路板的开发/移植。
采取了循序渐进的方法：
- 首先、 使用作为"所用工业通信 SDK：ind_comms_sdk_am64x_09_02_00_15"一部分提供的 EtherCAT 示例 在 带有 Beckhoff PLC 的 AM64x EVM 板上进行测试 这个测试很好、并且能够与 PLC 通信并且将参数发送到 PLC
- 定制电路板具有 AM6421、其中 PHY DP83822具有 MII 配置、PRU 端口与 EVM 电路板中相同。
- PHY DP83822驱动程序配置为 MII、下面提供了寄存器转储。
- 在 EVM 上测试的 EtherCAT 示例已移植到定制电路板。
- 通信失败
在移植过程中完成的操作
- 按照原样使用来自 EVM 的 EEPROM 数据。
- 使用 EVM 中的 PRU 固件原样。
- 使用与现在相同的 EVM 示例应用程序。
需要您的支持、以便向我们提供有关如何建立 EtherCAT 连接的一些线索。
这是 DP83822的寄存器转储
