@simon I have one question regarding DRAM traces on board. I noticed, at least for DDR4, that many board route the circuits in a weird way, this is apparently to make them same length and improve stability.
On R4 I don’t see this pattern, is it achieved in another way?
do we know if the current BPI-R4 revision is the last? I read something about when using the NVMe port one of the sfp+ ports doesn’t work correctly. Is that fixed?
Afair this is fixed in last version (1.2) and nvme put the i2c down so both sfp and the other devices connected to the same i2c are not usable (eeprom,rtc).
Hey friends
I recently purchased the WLE600VX (https://www.aliexpress.com/item/1005006980760083.html) wifi card to connect it to my router (banana pi bpi-r4) and the router fails to recognize it.
when I run the command “lspci” the output return empty.
I tried to install the following packages also without success:
ath10k-firmware-qca988x kmod-ath10k.
Has anyone managed to solve this case by any chance?
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?
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.
