I have an issue bringing up 1Gbps speed of ethernet1 on custom board which is modeled on Picozed SDR. It is able to work with 10/100 Mbps speed, but gives frame errors in case of 1000 Mbps. However, 1000 Mbps works well with Picozed SDR with default ADI Linux SD card image.
I know this is not a good place to ask about this issue, but just wanted to know if there were any special modifications done for Picozed SDR in xemacps driver(to support1000 Mbps speed & gmii2rgmii module) available with the ADI Linux SD card image? I don't have the liberty to switch to the latest MACB driver for ethernet1.
I am using the xcomm_zynq branch of ADI kernel source for my project.
