Part Number:PROCESSOR-SDK-AM335X
When AM335x connects USB Ethernet card with a USB cable, I encounter a USB communication stability problem, the Ethernet card is often lost randomly during operation. Reproduction method:Connect the USB network port to the network, then power on and start the board. After startup, the system continues to print error message cdc_ Ether 1-1:2.0 eth1: kevent 11 may have been dropped.How can I solve this probabilistic problem.

已咨询e2e产品线工程师,请关注下面帖子的回复。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1243107/am3358-usb-ethernet-card-is-unstable

请看下面e2e工程师的回复,建议使用最新的processor SDK。The SDK4.03 is very old and no longer supported. The kernel in SDK4.03 has several bugs in the USB controller drivers, which have been fixed in the newer kernels. Please tested with the kernel in the latest SDK.
