Need Help with M2U as WIFI Access Point


(Matt Johnson) #1

I followed the instructions here and in the forum and was not able to see the SSID from my mobile. I then followed the instructions in section #4 here: BananaPi BPI-M64(A64) New Image Android 8.1 & Ubuntu Release 2018-08-17 and was able to see it!

The problem is once I try to connect I see the following in ‘dmesg’:

[ 2881.570166] INTERNAL ERROR: FIRMWARE HALTED : set BUS DOWN

and the SSID disappears from my client machines even though it appears that hostapd is still running. If I do an ‘ifconfig’ the wlan0 interface is gone. Everything is fine until I attempt to connect.

It looks like a pretty hard error and not something related to a config file but just in case here they are:

Here is the full relevant ‘dmesg’:

Any idea what is happening here?

Here is the load module switches:

root@MyShowStudio:/var/lib/bananapi/bpi-init.d# more S10-bpi-hw-wifi.sh
#!/bin/bash
BOARD=$(bpi-hw)

load_modules()
{
  case ${BOARD} in
  bpi-m3)
    modprobe bcmdhd
    ;;
  bpi-m64)
    modprobe bcmdhd
    ;;
  bpi-m2m)
    modprobe bcmdhd
    ;;

    modprobe bcmdhd op_mode=2 firmware_path=/lib/firmware/ap6212/fw_bcm43438a1.bin
