标题: RK3568跑Ubuntu20.04遇到的Ethernet问题
我想在RK3568上测试一些APP,安装Package等,但是烧上系统之后,发现不能访问外网。
显示的错误如下:
[   54.867839] rk_gmac-dwmac fe2a0000.ethernet: Failed to reset the dma
[   54.867878] rk_gmac-dwmac fe2a0000.ethernet eth1: stmmac_hw_setup: DMA engine initialization failed

哪位大佬看一下,这个问题怎么解决?

你们是自研的产品吧,出这提示应该是硬件层导致的,芯片与phy芯片之间连接有问题用示波器抓一下波形分析下
