Hi all,

I bought a new odyssey board, but this one, unlike the ones I aquired last year, does not connect to wifi, and shows the following on the uart:

debian@npi:~$ sudo ip link set wlan0 up
[  858.685673] [dhd] dhd_conf_read_pm_params : PM = 0
[  858.690247] [dhd] dhd_conf_read_nv_by_chip : nv_by_chip_count=2

Also, the SD card used is the same I used on my older boards.

Please check the status and configuration of network interfaces by using the ifconfig or ip addr show command.

I did it, and it shows that wlan0 is down all the time. Also when using connmanctl it gives the following output:

debian@npi:~$ connmanctl
connmanctl> scan wifi
Error /net/connman/technology/wifi: No carrier

Hi there,
You won’t get any command response’s, I appears as if there’s NO radio…
or low level Driver issue , However the command errors look like the driver is wrong?

There is no battery. The board is being supplied by my computer usb port.

Idk about the NV chip. The board is brand new, but maybe some component is doa as you suggested.

:wink:

Hi.
Can you perform the Preparatory Work in its entirety with a new SD card? WiFi requires additional configuration as shown below
