EDK10.1 and emaclite

EDK10.1 and emaclite

[Georg Schardt]

Hi all,

im trying to use the emaclite core which comes with the EDK10.1 with the 
2.6.26 kernel from git.xilinx.com on virtex4fx12 minimodul. the emac is 
detect by the kernel:

xilinx_emaclite xilinx_emaclite.0: MAC address is now  2: 0: 0: 0: 0: 0
xilinx_emaclite xilinx_emaclite.0: using fifo mode.
xilinx_emaclite xilinx_emaclite.0: Xilinx EMACLite at 0x81000000 mapped 
to 0xC5060000, irq=0

i can change the mac-address with ifconfig and i can give an ip-address 
to the device,
but a ping is not possible and arp is not working. i think that the phy 
is not working right.

has someone others the same problem ? what can i changed ? i have tried 
out all possible phy driver in the linux  kernel

a setup with the lltemac is working fine, but i want to use the emaclite

thanks
regards
georg

Hi Georg,

I don't really know much about the state of the emac lite driver in the
Git tree. I inherited the Git tree with some stuff already in it.

I test the LL TEMAC driver, but haven't had the bandwidth and priority
to do any emac lite testing.

Thanks,
John

for the EMAC lite you don't need the hard temac. the work done by
the "hard temac" core and the plb_temac (or ll_temac) core together
in your old project will be done by the EMAC lite core alone.

so the signals to/from the broadcom PHY on your minimodule should be
connected directly to the EMAC lite core:

 	BEGIN opb_ethernetlite
 	 PARAMETER INSTANCE = etherlite
 	 PARAMETER HW_VER = 1.01.b
 	 PARAMETER C_RX_PING_PONG = 1
 	 PARAMETER C_TX_PING_PONG = 1
 	 ...
 	 BUS_INTERFACE sopb = opb
 	 PORT IP2INTC_Irpt = emac_interrupt
 	 PORT phy_rx_data = phy_rxd
 	 PORT phy_tx_data = phy_txd
 	 PORT phy_dv = phy_rxdv
 	 ...
 	END

(but this is probably getting off topic for this list.)

as john pointed out you can not access the PHY using only the EMAC
lite core. connect the MDIO and MDC lines of the PHY to a GPIO core.

then and use the bit banging driver of u-boot (start with #define CONFIG_MII
and #define CONFIG_BITBANGMII) or linux (search for CONFIG_MDIO_BITBANG,
i've not used it before).

fyi, on our minimodule boards the PHY is located at address #4, u-boot's
"mii info" command says:

 	PHY 0x04: OUI = 0x0818, Model = 0x0C, Rev = 0x01, 100baseT, FDX


for the inital setup you might want to connect the RJ45 of your
minimodule directly to your host pc, probably that's the easiest way
for you to see exactly what packets are travelling on the wire.

make sure that the negotiated speed is not 1000baseT, as the EMAC
lite can not handle that.

[John Linn]

Hi Georg,

There is no way to configure the PHY using the EMAC lite as that's part
of what makes it "lite".  =


So the PHY on the board has to be configured correctly by strapping it
on the board.

Maybe you can include other PHY drivers to do this as I'm not sure about
that.

Thanks,
John

sorry for the self-reply, but pinging from the minimodul increases the 
interrupts :-)
can you tell me the changes in the driver file ?

Yes, LEDs are blinking, an if a cable is connected the link leds are on. 
while pinging from the host pc the traffic led in front of the jack is 
blinking also

no interrupts on eth0:
  0:          0  Xilinx Interrupt Controller Edge      eth0

Yes, i will try this. i use this board with the edk 8.2 a year ago. with 
this edk version the emaclite was working fine. but in this project 
there was an ip core "Hard Temac" this is missing now. i think i have an 
error in my edk project.

I am using Emac but the configuration is more or less same for the two.

Look at the messages that I am getting at startup

[    3.225313] xilinx_emac xilinx_emac.0: MAC address is now  0:a0:22: 
1: 1:f2
[    3.264036] XEmac: using fifo mode.
[    3.288583] XEmac: *Detected PHY at address 0, ManufID 0x0040, Rev. 
0x61e4*.
[    3.328138] eth0: Dropping NETIF_F_SG since no checksum feature.
[    3.368685] eth0: Xilinx 10/100 EMAC at 0x11000000 mapped to 
0xC3020000, irq=5
[    3.404090] eth0: XEmac id 1.4a, block id 128, type 1

Points that you cant check

First look at ethernet interface RJ45 connector that power is coming, 
LED should blink.

1) check whether IRQ is right, its zero in your case. If it is right 
then issue ping and read interrupts arriving on your ethernet interface 
(cat /proc/interrupts), If number of interrupts are increasing then its 
sure that your PHY is ok , the problem is with mode selection (10 MBPS, 
or 100 MBPS) if that is the issue let me know , I'll tell you where to 
make changes in driver files.

2) If nothing of the above works then there is problem with PHY address 
detection. You have to look in hardware specification (your hardware 
board ) to find out PHY address.

Re: EDK10.1 and emaclite

[Georg Schardt]

Hi again,

mmh, there is no kernel message with PHY detection, but all PHY drivers 
are compiled in.
i looked at my xps project and there is only one ip-core "Ethernet_MAC" 
with type "xps_ethernetlite".
is it possible that the phy connection is missing ? i use the base 
system builder with the board support files supported from avnet.

where can i look for the ethernet speed ? the ethernetlite ip has no 
speed options

thanks for your help

Hi Georg,

Can you post linux bootup message where its says PHY is detected at 
paticular address, and check with your hardware what is actual address 
of PHY. Also I would like to know the configuration of your hardware 
whether its configured of 10MBPS OR 100MBPS.

Hi all,

im trying to use the emaclite core which comes with the EDK10.1 with the 
2.6.26 kernel from git.xilinx.com on virtex4fx12 minimodul. the emac is 
detect by the kernel:

xilinx_emaclite xilinx_emaclite.0: MAC address is now  2: 0: 0: 0: 0: 0
xilinx_emaclite xilinx_emaclite.0: using fifo mode.
xilinx_emaclite xilinx_emaclite.0: Xilinx EMACLite at 0x81000000 mapped 
to 0xC5060000, irq=0

i can change the mac-address with ifconfig and i can give an ip-address 
to the device,
but a ping is not possible and arp is not working. i think that the phy 
is not working right.

has someone others the same problem ? what can i changed ? i have tried 
out all possible phy driver in the linux  kernel

a setup with the lltemac is working fine, but i want to use the emaclite

thanks
regards
georg
