Problems with plb_temac+hard_temac+2.6.24rc3
Hi,
I am working with a ML403 platform and I have my kernel 2.6.24rc3 perfectly running on it. Almost everything seems to work but the ethernet. I am using the IP cores that come with the EDK 9.1sp2 ( plb_emac 3.00a + hard_temac 3.00b). The weird thing arises when I try to bring up the interface and use it. If I do "ifconfig eth0 up" the interface shows up but, strangely, it eithers not receives or send packets. I will explain myself, if I assing an IP manually and try to connect to another worksatation within the network ( by pinging from just one of the sides for example ) the interface seems only to send or receive packets , but generallty not both at the same time ( I can see this through the evolution of the Rx/Tx bytes in ifconfig). The only few times that both tx/rx work at the same time is when I do (ifconfig eth0 down and ifconfig eth0 up), but this only works sporadically and only for around a second or less.
This is what I get after the first "ifconfig eth0 up":
[ 293.258765] eth0: XTemac: Options: 0xb8f2 [ 295.253048] eth0: XTemac: speed set to 10Mb/s [ 295.256042] eth0: XTemac: Send Threshold = 16, Receive Threshold = 2 [ 295.256095] eth0: XTemac: Send Wait bound = 1, Receive Wait bound = 1 [ 297.252047] eth0: XTemac: PHY Link carrier lost.

and this after some ifconfig up/down:

It also seems to negotiate wrongly the speed since my network is 100Mb/s.

Try using hard_temac_v3_00_a with the ML403 board. There's an incompatibility (posted previously on this list) with PHY access. This could be causing the strange behavior you're seeing.

Subject: Problems with plb_temac+hard_temac+2.6.24rc3
Hi,
I am working with a ML403 platform and I have my kernel 2.6.24rc3=20
perfectly running on it. Almost everything seems to work but the=20 ethernet. I am using the IP cores that come with the EDK 9.1sp2 (=20 plb_emac 3.00a + hard_temac 3.00b). The weird thing arises when I try to
bring up the interface and use it. If I do "ifconfig eth0 up" the=20 interface shows up but, strangely, it eithers not receives or send=20 packets. I will explain myself, if I assing an IP manually and try to=20 connect to another worksatation within the network ( by pinging from=20 just one of the sides for example ) the interface seems only to send or
receive packets , but generallty not both at the same time ( I can see=20 this through the evolution of the Rx/Tx bytes in ifconfig). The only few
times that both tx/rx work at the same time is when I do (ifconfig eth0=20 down and ifconfig eth0 up), but this only works sporadically and only =20 for around a second or less.
This is what I get after the first "ifconfig eth0 up":

That is correct. I changed to hard temac 3.00.a and everything seems to work perfectly now.
Thank you very much for your help,

Try using
hard_temac_v3_00_awith the ML403 board. There's an incompatibility (posted previously on this list) with PHY access. This could be causing the strange behavior you're seeing.-Rick

Subject: Problems with plb_temac+hard_temac+2.6.24rc3Hi,
I am working with a ML403 platform and I have my kernel 2.6.24rc3
perfectly running on it. Almost everything seems to work but the ethernet. I am using the IP cores that come with the EDK 9.1sp2 (plb_emac3.00a +hard_temac3.00b). The weird thing arises when I try tobring up the interface and use it. If I do "ifconfig eth0 up" the interface shows up but, strangely, it eithers not receives or send packets. I will explain myself, if I assing an IP manually and try to connect to another worksatation within the network ( by pinging from just one of the sides for example ) the interface seems only to send or
receive packets , but generallty not both at the same time ( I can see this through the evolution of the Rx/Tx bytes in ifconfig). The only few
times that both tx/rx work at the same time is when I do (ifconfig eth0 down and ifconfig eth0 up), but this only works sporadically and only for around a second or less.
This is what I get after the first "ifconfig eth0 up":
[ 293.258765] eth0: XTemac: Options: 0xb8f2[ 295.253048] eth0: XTemac: speed set to 10Mb/s[ 295.256042] eth0: XTemac: Send Threshold = 16, Receive Threshold = 2[ 295.256095] eth0: XTemac: Send Wait bound = 1, Receive Wait bound = 1[ 297.252047] eth0: XTemac: PHY Link carrier lost.[ 299.251657] eth0: XTemac: PHY Link carrier restored.and this after some ifconfig up/down:
