(如下 log 获取自 orangepi_one， 基于H61X 的 orangepi zero3, zero2w 也有一样的问题)
我在最新的uboot 上，尝试使用 RNDIS 功能，
uboot 中做了如下设置，
setenv ethact usb_ether
setenv ipaddr 192.168.2.100
setenv serverip 192.168.2.1
然后尝试使用 tftpboot zImage 来获取文件， 工作正常
=> tftpboot zImage

以后再次尝试也无法恢复， 除非重启
在网上找了很久，没有线索，是不是和 auto suspend 有关？
各位有遇到这种情况的吗？
