Hi,

any hope to have a 5.x server image with support for the M1 bluetooth soon ?

unfortunately it seems till unsupported in last 5.17 official images

Perhaps because due to the lack of /dev/ttyS2 used by BT ?

However it appears in dmesg :

 

[    3.275178] ff130000.serial: ttyS2 at MMIO 0xff130000 (irq = 20, base_baud = 1500000) is a 16550A
[    3.275619] serial serial0: tty port ttyS2 registered

 

What is missing ?

A check of Armbian_22.05.0-trunk_Station-m1_sid_edge_5.18.0_xfce_desktop.img.xz shows same thing.

Looking deeper I see a unit related to bluetooth and it's uart which is dead :

 

root@station-m1:# systemctl status sys-devices-platform-ff130000.serial-serial0-serial0\x2d0-bluetooth-hci0.device
○ sys-devices-platform-ff130000.serial-serial0-serial0x2d0-bluetooth-hci0.device - /sys/devices/platform/ff130000.serial/serial0/serial0x2d0/bluetooth/hci0
     Loaded: loaded
     Active: inactive (dead)

 

Try to restart it :

 

root@station-m1:# systemctl start sys-devices-platform-ff130000.serial-serial0-serial0\x2d0-bluetooth-hci0.device
Job for sys-devices-platform-ff130000.serial-serial0-serial0x2d0-bluetooth-hci0.device timed out.

So there is something broken around that unit (dtb ?).

An idea ?

Maybe another track around the firmware :

dmesg |egrep -i "RTL|hci0"

the files exist

ls -l /lib/firmware/rtl_bt/rtl8723ds*
-rw-rw-r-- 1 root root    47 May 20 12:25 /lib/firmware/rtl_bt/rtl8723ds_config.bin
-rw-rw-r-- 1 root root 48988 May 20 12:25 /lib/firmware/rtl_bt/rtl8723ds_fw.bin

 

but the loading fails.

Bad firmware ?

Or something to do with this (old ?) bug :

Realtek Bluetooth controller failed to download firmware larger than 32K ?

This bug is fixed in current module.

 

Does anyone know where to look to debug or help to debug the bluetooth on Station M1 ?
