Hi all!
Yesterday i encountered problems with BCM4356 wireless chip (it is built-in on Firefly RK3399, so SDIO bus is used to access it): i cannot connect to my wireless AP in 2.4GHz band. At the same time all is OK if i am connecting to 5GHz AP. When connecting manually i get following output from wpa_supplicant:
wlan0: Trying to associate with SSID '1473'
wlan0: CTRL-EVENT-ASSOC-REJECT bssid=00:00:00:00:00:00 status_code=16
So, AP is detected but it can't connect to it. iw list shows 2.4GHz channels from 1 to 13 working (AP works on 3). Also i have following lines in dmesg:
[ 16.315372] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4356-sdio for chip BCM4356/2
[ 16.315715] usbcore: registered new interface driver brcmfmac

If i try to create an AP from it, i get messages like
failed to set tx queue parameters
and other devices don't see this AP
So, what could be the problem and how could it be solved?
The issue was resolved after reinstalling bootloader. I don't know how
