[Barrelfish-users] 答复: 答复: barrelfish on scc, how to ping the cores

Wed Mar 7 10:45:46 CET 2012

Hi Pravin,

Thank you for your advice, I have tried your solution, but it doesn’t work.
Because my scc board doesn't have a useable PHY 2 ethernet ports (Usable GB ETH 1101), I replace "eMAC_eMAC2_" with "eMAC_eMAC3_" to use the emac d ( PHY 3).

Do I have to use the echoserver if I want to ping the cores? But the echoserver seems doesn't work (after printing chips: client waiting for eMAC3_0_CTRL, it seems stall).
When I ping rck00~rck47, /dev/crbif0rb0c0ttyS0 outputs something like 
EMAC: ######## interrupt came!
EMAC: #### interrupt handling!

But I get "From rckhost.ex.rck.net (192.168.10.254) icmp_seq=5 Destination Host Unreachable".

Menu.lst.scc
......
# modules needed to start the networking
module  /scc/sbin/eMAC core=0 device=3
module  /scc/sbin/netd core=0 cardname=eMAC3_0
module  /scc/sbin/eMAC core=1 device=3
module  /scc/sbin/netd core=1 cardname=eMAC3_1
module /scc/sbin/echoserver core=0 cardname=eMAC3_0
......

The crbif output is as follows:

Hi Zhuwangbin,

By looking at your menu.lst.scc and output, my understanding is that you are using PHY connection 0 out of 4 PHY ethernet ports provided by SCC.  Unfortunately, the eMAC driver was programmed to work with PHY 2.  This is mostly due to some hard-coded function calls in file usr/drivers/eMAC/eMAC_hwinit.c.  You can find these function calls by searching for a string "eMAC_eMAC2_".  In all these function calls,
eMAC2 specifies that PHY2 is to be used.  Ideally this should have been decided by device-id provided as command line argument, but this driver was written in little hurry and hence ended up having hard-coded PHY.

So, my suggestion will be to re-connect the ethernet cable to PHY2 on SCC and modify the menu.lst.scc accordingly, and hopefully this should work.  Other option is to keep the ethernet cable on PHY0 and edit eMAC_hwinit.c to replace "eMAC_eMAC2_" with "eMAC_eMAC0_".  I have attached a patch with this email for this.  As per my understanding, this patch should work, but I haven't tested it!  So, I can't assure that it will work.  I would recommend connecting the cable to PHY2, as we know that our code works with PHY2.

I hope this helps.
Pravin
