esp8089 on licheepi_nano with 4.15 kernel #45

Hi, I tried to compile and install the driver on my board but I get the following output in kernel log (I'm not sure if it is an error):

    broken-cd;

};
...

The chip is connected within the memory card slot. I can see the wlan0 with ip a command but I can't connect to any network with wpa_supplicant, I get the below error (I'm not sure if this is related to driver or not):

# wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D wext

Thanks.

I haven't tried this driver with any other platforms than Pi Zero / A+ / 2B+ so I can't help much with platform specifics. I know that @Icenowy has a branch for LicheePi plus their custom SDIO card in this fork: https://github.com/Icenowy/esp8089/tree/cleanup .

It's been a while so I could be mistaken, but I thought it was normal to see some probe errors. Out of reset the ESP is running a bootstrap program out of ROM that establishes SDIO comms with the host and waits for the runtime firmware to be downloaded into RAM. Once the firmware is downloaded and starts executing, the ESP has to redo the SDIO handshake which produces that error. (edit: the message is expected as I noted here.)

As for the ioctl error, that may have to do with wpa_supplicant (first Google hit here), but I wonder if the RFKILL error may be related.

Feel free to respond to this, but as I'm certain it's not a driver error I'm going to mark this closed.

Thanks for the info, I tried the driver you mentioned but get the exact same behavior. The /etc/network/interfaces didn't work for me as it can't connect to my AP. I tried to use wpa_supplicant and then try the wpa_cli, but whenever I scan for APs I get only one or two APs and I even can't see my own AP in the scan result list. So I can't connect to either network. I'm also using an external antenna on the board. After one or two minutes of the scan, I get some error messages in the console. I'm adding the full console log maybe it helps. (I updated the kernel to 5.2)
