您好！
我正在使用评估板" TMDS243EVM - PROC101C (005)"以使用 ICSS-EMAC 使用示例" hsr_mII_demo_am243x-evm_r5fss0-0_freertos_ti-arm-clang "(此样本使用 ICSSG1 )。
我的目标是查看电路板是否能够回复 Ping。
-一切都好, ping 工作正常。
我们正在开发一款使用 DLP 技术的 ICSSG0 (而不是 ICSSG1)。
为了对其进行测试、我在.syscfg 文件中将 ICSSG1更改为 IGSSG0、但无法对其执行 ping 操作。
我们是否需要更改 PRU 固件以使其正常工作、还是我漏掉了其他内容？
此致
更新主题：
用于测试的演示是 SDK 中的 HSR/PRP 演示。 在其电路板上运行此示例时、不会发送或接收任何内容。 这两者的日志如下所示。

实现的支持定制电路板的更改包括：
从".syscfg"文件禁用不必要的组件：
文件修改：
#hsr_prp_soc.c
#ifdef HSR_PRP_RGMII
void hsrprp_rgmii_init()
{
ETHPHY_DP83869_LedSourceConfig ledConfig;
…
hsrprp_configure_rat();
}
#endif /* HSR_PRP_RGMII */
