Subject: [U-Boot] U-boot 2010.12 Ping failed on DP83849C
Date: Fri, 6 May 2011 08:05:18 -0700 (PDT) [thread overview]
Message-ID: <341234.23759.qm@web111806.mail.gq1.yahoo.com> (raw)
I have a custom MPC8313ERD board loaded with u-boot 1.1.6 and the network PHY is
NetSemi DP83849C. The PHY info is copied from DP83865 and the network works
fine.
Recently I am trying to upgrade u-boot to 2010.12 but I got Ping failed and host
is not alive message when I ping the same host.
After enabling debug, it shows:
Trying TSEC0
Speed: 10, half duplex
Using TSEC0 device
sending ARP for 0a350275
ARP broadcast 1
TSEC0: tsec: tx error
ARP broadcast 2
TSEC0: tsec: tx buffers full
ping failed; host 10.53.2.117 is not alive
After googling the problem, I learned this may be related to the some kind
of bus conflict when DMA move ip packet to transmit bugger.
My question is what caused this error in 2010.12 version and not in 1.1.6?
