Support for Raspberry Pi 3B+

[JonM]

A little more info:
This seems to happen with one Dell keyboard so far. Changing keyboards will cause the issue to disappear.

Enclosed is the output of dmesg -w. Look at [ 217.993749]. Hopefully it is helpful.

Hi @JonM, i think that you don't see the errors, because you haven't set up correctly the blue interface.
In my case the issue shows up when i enable hostapd and sent/receive some traffic over blue interface, and in parallel receiving/sending traffic over red and green interfaces. It seems like the hardware does not support too much traffic, maybe because all the three interfaces are using the same bus. I will try the new core 127, maybe works. I will post my tests in the next days.

Regards

@Challenger - I went from a red/green setup to a red/green/blue setup and I don't see the same errors. (disclaimer - I am not one of the experts. I am just a user like you).

My setup:
• Raspberry Pi 3 Model B+
• IPFire 2.21 (armv5tel) - Core Update 126
• green = Onboard LAN ethernet port - Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
• red = USB-to-Ethernet adapter - Trendnet TU3-ETG (with AXIS AX88179 Gigabit internals)
• blue = on-board wifi via sdio: brcmfmac
• addons = hostapd, nano, iperf3

I don't see any of the errors like the ones in your log and I don't have any of the kernel panics. But I also cannot get the hostapd add-on to work correctly. I cannot connect from the blue network to the Internet. I can access the IPFire box and connect to the WUI just fine. So I think I've set something wrong!

These are the only issues I see:

More testing to do!

The WLAN Module on the RPi 3B+ doesn't work if the Region is not configured ("00"). Other modules falls back to "World" - channel 1-11 bg mode.
Configure your region on the WlanAP page in the webgui then the wlan should work.

Updated my RasPi3+ to Core 128 (test).

My setup:
• Raspberry Pi 3 Model B+
• IPFire 2.21 (armv5tel) - Core Update 128
• green = Onboard LAN ethernet port - Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
• red = USB-to-Ethernet adapter - Trendnet TU3-ETG (with AXIS AX88179 Gigabit internals)
• blue = USB-to-Ethernet adapter - CableCreation CD0026 (with Realtek RTL8153 Gigabit internals)
• addons = nano

Hast du da noch USB Geräte dran die du nicht brauchst. Sieht für mich aus als ob der keine DMA Kanäle mehr frei hat und da ein Gerät zu viel dran ist. Der USB Treiber ist da echt verbuggt. Und der Gigabit/Hub chip braucht noch einen Kanal (da es intern zwei Hubs hintereinander sind) mehr als der alte 100mBit chip vom RPi3B (ohne plus)

[JonM]

Hi Arne! In English please.

I tried the Google translate but I'm not sure I understand.

[DJ-Melo]

"Do you have there still USB devices to which you do not need. Looks to me as if the DMA channels no longer has more free and because a device is too much. The USB driver is really bugged. And the Gigabit / Hub chip still needs a channel (because there are two hubs in a row internally) more than the old 100mBit chip from the RPi3B (without plus)".

Try less usb devices
