U-Boot Network Setup (MitySOM-5CSX-H6-42A)
Added by Jose Berlioz over 2 years ago
Hello,
I was trying to load the kernel and fpga files through a TFTP server. I have to use a static IP for this as a requirement (cant use dhcp).
Is there any setup I have to do besides establishing environment variables on U-boot? I can't seem to be able to ping my server or my gateway (192.168.1.1) from my devkit, even though I am able to ping it from Yocto.
I am using a 5CSX-H6-42A Mitysom with the standard CriticalLink image.
This is the console message I get when I use ping:
MitySOM-5CSx # ping 192.168.1.1
designware_board_phy_init: enter
Waiting for PHY auto negotiation to complete............. TIMEOUT!
ENET Speed is 10 Mbps - HALF duplex connection
Using mii0 device
ping failed; host 192.168.1.1 is not alive
This is the environment variables loaded on U-boot:

Hi Jose,
Are you using a MitySOM-5CSX Development kit board, or a custom carrier board?
The first couple of lines:
aiting for PHY auto negotiation to complete............. TIMEOUT! ENET Speed is 10 Mbps - HALF duplex connection
are very suspicious. I assume you are using a switch that is at least 100 Mbps?
This could be because the ethernet reset line is not being asserted or released correctly, or it could indicate other issues with the PHY MII interface to the SOM. I thought that our default u-Boot scripts included GPIO commands to toggle the ethernet reset pin as part of the bootcmd script to ensure the PHY reset with the correct boostrap options (after the SOM was powered). I am not seeing that in your environment. There should be an "initphy" or "initeth" u_boot script command in the stock environment.

Hey Mike,
Yes, I have a 300Mbps switch, but I can test it in a faster one. I am also testing it in the devkit, not the custom board.
When yocto comes up, it looks like it is able to get to 100Mbps:
socfpga-dwmac ff702000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx
and is able to ping too:
root@mitysom-c5:~# ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=1.35 ms
I also had issues with my image so I was trying this with the SD Card image given in the CriticalLink website for the 5CSX-42A. The only thing that was changed were adding the ip address environment variables. Can you post the script in here since I can't seem to find it? I can add it manually.

Hi Jose,
You can make the following changes to the U-Boot environment to enable Ethernet:
initphy=gpio clear 28; gpio set 28; sleep 1
preboot=run initphy; run setup_usb; ab1805 cs ${rtccal}
You'll also need to set the ipaddr environment variable to assign a static IP to the board.
Note that although the sleep in initphy is only one second, it may take another few seconds for the PHY to actually come up. After that, you should be able to ping/TFTP.

That did it.
MitySOM-5CSx # ping 192.168.1.1 designware_board_phy_init: enter Waiting for PHY auto negotiation to complete. done ENET Speed is 100 Mbps - FULL duplex connection Using mii0 device host 192.168.1.1 is alive
