[FAQ] MCU-PLUS-SDK-AM243X: 如何在 MCU+ SDK Enet LLD 中使用调试 GEL 文件获取 CPSW 诊断统计信息？

可以通过以下步骤打印 CPSW 统计信息 -

1) 启动 CCS 并连接到主 R5F0_0 内核

2) 在顶级菜单中点击“Tools”-->“Gel Files”选项

3) 在新打开的“GEL Files”窗口中，右键点击并选择“Load GEL”

4) 选择文件 mcu_plus_sdk_xx_xx_xx\source\networking\enet\core\tools\debug_gels\cpsw_startup.gel

5) 点击“Scripts”-->“CPSW Statistics Print”-->“cpsw_2g_ststsprint_nonzero”，您将在 CCS 控制台上看到统计信息寄存器。

以下是 examples\networking\lwip\enet_lwip_cpsw 的样例输出（使用端口 1）：
