hi expert

sdk7.3 qnx+rtos

When I use SGMII MAC2MAC driven by cpsw9g,and test communication using iperf3 udp，i have some problems

problem 1：

SOC1 COMMAND:

io-pkt-v6-hc -d cpsw9g tx_descriptor_cnt=256,rx_descriptor_cnt=256

ifconfig an0 192.168.0.100

iperf3 -s

SOC2 COMMAND:

io-pkt-v6-hc -d cpsw9g tx_descriptor_cnt=256,rx_descriptor_cnt=256

ifconfig an0 192.168.0.101

iperf3 -c 192.168.0.100 -u -p 5201 -t 10 -i 1 -w 200k

then i run the soc2 command four seconds later ，SOC2 No response from terminal ，SOC1 running log is next

if i test communication using iperf3 with iperf3 -c 192.168.0.100 -p 5201 -t 10 -i 1 -w 200k , do not use udp it is ok

Does mac2mac not support UDP transmission？

What problem caused this ？

how can i fix this？

problem 2：

at the some board sdk7.3 qnx+rtos

i use RGMII + PHY drived by cpsw9g

i test communication tda4 and pc，

pc command is iperf3 -s -d

tda4 use the same command “iperf3 -c 192.168.0.100 -u -p 5201 -t 10 -i 1 -w 200k”

it runs ok but thepacket loss rate is too high ，The packet loss rate is as high as 75%，CPU utilization is basically 0.01%

What problem caused this ？

how can i fix this？

hi expert

problem 2 Has been resolved

but problem 1 ,TWO pcs TDA4 SGMII3 MAC2MAC communication test uesing iperf3 -c -u Still exist

Hi,

MAC2MAC has nothing to do with UDP or TCP/IP. It's likely that there is a basic issue with the connection. How have you verified SGMII MAC 2 MAC ? Do you have any Hardware statistics ?

Can you run the GEL files located in pdk/packages/ti/drv/enet/tools/debug_gels/ and get the statistics dump ?

Regards

Vineet

hi vineet

thanks for your replay

Maybe you don't understand my description ，i use sdk 7.3 QNX + RTOS

I use two tda4. They communicate with sgmii4. At this time, only sgmii4 is working normally between the two tda4 I think The connection has been successfully .

the log is

then i use command on one of sgmii4 like

ifconfig an0 192.168.0.100

iperf3 -s

another tda4 use next command

ifconfig an0 192.168.0.101

iperf3 -c 192.168.0.100 -p 5201 -t 10 -i 1 -w 200k

the communicate is ok the log is

but if i use

iperf3 -u -c 192.168.0.100 -p 5201 -t 10 -i 1 -w 200k

the iperf server is still running but the iperf3 client no respon

the log is

so i mean if is use iperf 3 -c, test the communication it is ok

if i use iperf 3 -u -c ,the clinet no repsone and i cannot input anything with terminal

and i found if reduce the parameter -w 200K to 20K which is iperf3 the client Normal operation for two seconds
