New Kernel Wi-Fi AP6212 driver is no good.

[JimmyChangJY]

I follow the guide. And build the whole system again. BTW The new system can run Chromium smoothly.

But I found the Wi-Fi is not working.
So I update the driver frome below https://github.com/BPI-SINOVOIP/BPI_WiFi_Firmware/tree/master/ap6212 Right now the wifi work perfectly.

Below is before I fix the driver dmesg log.

dmesg|grep fail

Thanks for the info, you must have a new revision board with updated Wifi chip. My board is rather old. You have A1 chip.

[ 15.652584] dhdsdio_download_code_file: Open firmware file failed /lib/firmware/ap6212/fw_bcm43438a1.bin

[ 8.211648] sunxi-mmc 1c11000.sdmmc: smc 1 p2 err, cmd 52, RTO !! Don't worry, It is not really an error per si, it's trying to detect some mmc memory type.

[avafinger]

Can you please check if BT (Bluetooth) is working with this A1 chip?

[avafinger]

BT will possibly not work if you have not manually changed it to load the A1 firmware, so i just made this script to do it, please try: https://github.com/avafinger/bpi-m64-firmware#things-you-should-do-after-flashing-the-os-image

Note: If BT is not working it will eat a lot of CPU if you try to use BT.

[JimmyChangJY]

BT also need to modify new driver https://github.com/BPI-SINOVOIP/BPI_WiFi_Firmware/tree/master/ap6212 And BT work smooth.

My wifi has new issue. dmesg|grep fail [ 673.825828] dhd_aoe_hostip_clr failed code -1 [ 673.825832] aoe_update_host_ipv4_table failed

I can see the whole wifi connecting info is correct. DHCP setting can let me get the correct IP. But I can't ping my router IP address. Any Idea?

[avafinger]

Please, run the script and check again: https://github.com/avafinger/bpi-m64-firmware/commit/c439b5be30dc4606f56d48d2c50a9b0332ad4fd9

[JimmyChangJY]

:+1: FYI In the C439b5b 91 line

• wget https://github.com/avafinger/bpm64-firmware/raw/master/update_wifi_bt.sh is wrong !

It should be https://raw.githubusercontent.com/avafinger/bpi-m64-firmware/master/update_wifi_bt.sh

[avafinger]

Fixed, thanks.

[JimmyChangJY]

GOOD for you !! avafinger
