Other Parts Discussed in Thread: AM3352, TPS65910
How to reproduce
I am using two AM3358 AR8035 chips.
$ udhcpc -ieth0
$ udhcpc -ieth1
Eth0 IP: 192.168.100.29
Eth1 IP: 192.168.0.14
On a linux pc
$ iperf -c 192.168.100.29 -u -i 1 -t 10000 -b 1000M
On board
after $ifconfig eth0 down
After confirming that packet is not transmitted in Linux PC
<Linux PC>
[3] 92.0-93.0 sec 3.92 MBytes 32.9 Mbits/sec
[3] 93.0-94.0 sec 0.00 Bytes 0.00 bits/sec
[3] 94.0-95.0 sec 0.00 Bytes 0.00 bits/sec
[3] 95.0-96.0 sec 57.5 MBytes 483 Mbits/sec
[3] 96.0-97.0 sec 97.0 MBytes 813 Mbits/sec
$udhcpc -ieth0 or ifconfig eth0 192.168.100.29 up
Even though it is linked, it does not receive data.
The workaround is
$ ifconfig eth1 down; ifconfig eth0 down
$ ifconfig eth0 192.168.100.29 up
If you do, you can communicate again.
When testing ping or iperf -c 192.168.100.29 -i 1 -t 1000 (TCP transmission) on a Linux PC
No problem occurs.
The cause seems to be that the internal CPSW is broken when data comes in through UDP during the Ethernet initialization process.
I'm looking for a solution.
