Errors if run DOA application on Orange Pi 4 LTS

1

Hi,
I have an Orange Pi 4 LTS (Orange Pi 4 LTS - orange pi 4 lts) and want to use it with KrakenSDR.
Everything was installed well through the installation script krakensdr_aarch64_install_doa.sh. I can get into the web interface. But after running kraken_doa_start.sh in dmesg I see errors in dmesg: [ 3305.712876] usb 2-1-port2: disabled by hub (EMI?), re-enabling…
And status in web application is red.

Full output from dmesg:

Kernel version:

# uname -a
Linux orangepi 5.15.80-rockchip64 #22.11.1 SMP PREEMPT Wed Nov 30 11:12:47 UTC 2022 aarch64 GNU/Linux

I checked the USB cables, everything works with a regular computer.
Question: how can I fix this problem?

Thank you!

Are there any messages in the KrakenSDR log files in the DOA or heimdall folders?

What OS are you running?

One thing i’ve noticed with the OPI4 is that it’s very sensitive to it’s own power requirements. Are you powering via USB-C or the DC Barrel port?

Are there any messages in the KrakenSDR log files in the DOA or heimdall folders?

Will show in the evening.

What OS are you running?

i tried original OS (Debian 11 and Ubuntu) for OPI4 and different versions of armbian.

Are you powering via USB-C or the DC Barrel port?

I use USB-C.
Also thought about it. I’ll look for a power supply to test your assumption.

I had major issues trying to get the OPI4 to work nicely via USB-C as well, so I recommend trying the DC barrel port first if possible.

Found a 5V 4A power supply DC Barrel port for OPi4
Nothing has changed - it doesn’t work.

Based on what I see here: Orange Pi 4 LTS - orange pi 4 lts
It advertises 1x USB 3.0 and 2x USB 2.0

Someone on RR had your same error, and fixed it by going to the USB 3.0 port. Double check that perhaps?

OR if it is still a power issue, what kind of power supply do you have for your KrakenSDR?

If connect KrakenSDR to USB3 (Above) I get errors:

It’s on original OrangePi 4 LTS image Orangepi4-lts_3.0.6_debian_buster_server_linux4.4.179.7z with Linux4.4. I took version 4.4, because, the documentation says that all devices are supported on this version.

8

As a result, it worked using the interface Type-C <-> Type-C.
I don’t know why USB2 and USB3 interfaces don’t work. I do not think that this is due to insufficient power supply KrakenSDR. Because if instead of OrangePi4-lts I take RPi4 B+, then everything works.

9

There’s no power supplied through the data USB cable anyway.

Hmm odd finding. I have the OPI4 working with the KrakenSDR via the regular USB ports, on both Armbian and Orange Pi’s distro. I have not tried the USB-C power for data yet.

The USB-C doesn’t work for powering the OPI4 though.

Could be some weird variances between OPI4 devices.
