ROCK Pi 4 resetted in stress test with USB3.0 and Gb Ethernet

#1

Hi

I’m testing to replace my application from Raspberry PI3B+ to ROCK Pi 4 for performance issues.

My ROCK Pi 4 resetted after few days(one or two) in stress test with heavy load on USB3.0 and Gb Ethernet.

Do you know the cause?

Did anyone check whether there is any problem with this test?

Test environment:
Model: ROCK Pi 4 1GB
OS: ARMBIAN 5.67 user-built Debian GNU/Linux 9 (stretch) 4.4.154-rk3399rockpi4b
USB 3.0 device: 128GB ssd(performance 180GB/s)
Attachment: Heatsink, cooling fan
Gb Ehernet : GbE 8port hub

Core temp while testing: 60 - 70

Gb Ethernet test code:
client(rock pi4):
sudo route add -net 224.0.0.0/4 dev eth0
iperf -c 224.0.55.55 -u -T 32 -t 10000000000000 -i 1 -b 1G --udp-counters-64bit

server(pc):
sudo route add -net 224.0.0.0/4 dev eth0
iperf -s -u -B 224.0.55.55 -i 1 --udp-counters-64bit

USB 3.0 test code(rock pi4):
watch dd if=/dev/sda of=/dev/null

Thank you.

Hi,

I don’t quite get it about the testing of USB3.

USB 3.0 test code:
watch dd if=/dev/sda of=/dev/null

This should be running on the ROCK Pi 4, right?

Yes, read all the SSD sectors endless through USB3.0 .

Ok, we will try to reproduce it here.
