Linux/PROCESSOR-SDK-AM437X: USB boot

Sriram V

Tool/software: Linux

Hello,

I have connected AM437X GP EVM to my Linux PC. My Linux PC is a Ubuntu 16.04. When i connect it for USB boot.

The Linux PC reports that RNDIS init has failed. I tried it on Ubuntu 14.04 and the latest 17.04 as well as with the same results.

I wanted to check if Linux Ubuntu 14.04 or 16.04 has been used to test USB boot? I have tried USB boot on multiple ubuntu distributions

with the same results. Can anyone share their Linux setup details or host enviroment on which USB boot has been tested.

Thanks for your help.

Hi,

Yes i have. But the problem we are seeing is on Ubuntu 14.04, 16.04 and 17.04.
As soon as we connect the Board to the Host PC. We get the error

[28109.008534] rndis_host 2-3:1.0: RNDIS init failed, -110
[28109.008553] rndis_host: probe of 2-3:1.0 failed with error -110

Also, Do i need any new packages/workarounds on my host pc to get RNDIS working.

Thanks,

Sriram,

I used 12.04 and 14.04 and don't recall any additional steps to get this working. Obviously, to get the whole process to work, you will need a DHCP server and TFTP server, but it seems the problem you are seeing is lower level than that. I did not see this problem and I don't recall any additional packages needed.

Just to add more detail for anyone that finds this later. This problem was confirmed with Ubuntu 16.04, but Ubuntu 14.04 with kernel version 3.13.0-128-generic seemed to work fine. It seems that there is some incompatibility between the AM437x and the later Linux Host drivers for RNDIS.
