Banana Pi BPI-R4 Wifi 7 router board with MediaTek MT7988A (Filogic 880),4G RAM and 8G eMMC

[fengaiyu]

How to setup or inplement the AFC(Automated Frequency Coordination) in 6GHz? Hardware:Banana pi R4+WiFi7:BPI-R4-NIC-BE14 We have already completed the AFC DUT test Harness on the computer(6 GHz AFC Resources | Wi-Fi Alliance). Is there any information about AFC?

[Avamander]

AFC requires, well, automated frequency coordination. This entails something like running afcd (having it connect to the coordinating organization) and then hostapd (or equivalent) with its support.

I’m not aware of any publicly usable implementations of the former just yet. You have to use the low limits that are allowed without AFC.

[fengaiyu]

Thanks,your answer is useful to me. Maybe the “afcd” is what i want. Like these features:[PATCH v7 1/4] hostapd: afcd: add AFC daemon support (Linux Host AP)

[kvic]

FYI. A different vendor’s board has similar, if not exactly same, traces between MT7988a and memory chips.

AsiaRF Wifi 7 module

[AA] One member asked about the ‘straight traces’ between SoC and memory chips. This board has the same pattern as BPI R4. Hence, I conclude it’s likely from reference design/recommended design by MediaTek. So indeed nothing to worry about.

Atheros AR5BXB63 recycled here…ok, It Is really old, but works fine… Any info about the official wifi7 nic realase?

[Lorem_amicus (Michael Fischer)]

OpenWrt One/AP-24.XY is an upcoming router board developed by OpenWrt and Banana Pi

Did you talking about the wifi 7 modul for BPI-R4?: https://de.aliexpress.com/item/1005007223137654.html But please, there are other chats for the wifi 7 NIC BE14 and BPI-R4: or:

Just putting this out there as cannot find much information on it, other than SINOVOIP’s getting started wiki.

Has anyone managed to get a Quectel RM520N-GL module working in CN16 M.2 B slot?

Device does not appear to initialize upon boot, i’m not wanting to use an outdated verison of OpenWRT (sinivoip BPI-R4 images) due to not being able to install new drivers/packages etc…

[frank-w]

please create own thread for special 3rd party hardware…this thread is about 355 posts log…so the answer gets lost for all who have same problem

[nezar_taima]

I have two 5G modules from quectel (RM520N-GL & RM520N-EU), both works okay inside R4 board. BTW, using mainline openwrt not official image.

[Karasik]

Do SFPs (I have DFP-34X-2C3) work in OpenWRT snapshot? I can’t log into the web interface, build 21.02 works without problems.

ethtool is the same in both versions:

[frank-w]

please do specific extra hardware in separate threads…afaik there is already one for the DFP-34X-2C3 where someone created patches for (afair rejected upstream so far)

this thread goes very messy because of different topics mixed

Does someone have an issue in recent builds (since 2 weeks), that device freeze with kernel panic:

and after reboot, it goes to the initramfs and only unplug power for few seconds and turn on works? I suspect that the microSD card is broken, but on second one (very old) issue comes again.

[frank-w]

Please create new topic with operation system and version. For me it looks like an error-pointer is used as memory address.

0xf…f98 should be -104 which is “connection reset”

[danpawlik (Dan)]

thanks @frank-w . I will do, but first I need to collect some logs Just leave a msg for others, if someone have similar issue- my guess is related to mt7925e and recent update for mt76 in OpenWRT (probably it starts since this: mt76: update to Git HEAD (2024-08-16) · openwrt/openwrt@20bf5f3 · GitHub )

EDIT: Issue created: mt7925: Kernel panic after authentication · Issue #909 · openwrt/mt76 · GitHub

[ljy26 (arkin jade)]

hope experts here can help me with this issue, currently using FM350GL / lastest snapshot , getting good speedtest around 600mbps but when upload starts , R4 will reboot due to kernel panic.

[M10 (M)]

So, wifi be14 module arrived, mounted it , and after i’ve connected power board is not booting, nothing on serial, straight after power red pwr led and next g led green lights up and thats all… Someone have an idea how to diagnose this dead men?

[Mathieulh]

Did you set SW4 to the “on” position? (to supply 12V to the BE14)

[M10 (M)]

Yes, i did, but now without module board is also dead…

[nextgen-networks (raupe)]

… you “may” have touched/changed the sdcard/emmc/nand boot selector switch while installing the wifi module (happened to me a couple of times).

[M10 (M)]

Yes, but all combination don’t work, no boot blue led, also serial console is silent… Maybe later i’ll have some time to compare to my other one ( have three devices).
