4 Booting and WLAN Bring-Up

The following steps use HW setup using AM335x EVM along with WL1837MODCOM8I module. The SD card can now be mounted to SDMMC1 slot on AM335x EVM. Connect UART cable from J12 UART connector to PC. Run any terminal program (ex: TerraTerm) with baud rate configured to 115200, 8 bits, no parity. BeagleBone Black along with Element 14 Wireless Cape can also be used as an alternative to the below setup.

The following message should appear during the kernel boot, which indicates that the driver is up and WiLink8 FW is downloaded. 

[   28.358451] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11)
[   28.478778] wlcore: loaded
[   29.515823] wlcore: PHY firmware version: Rev 8.2.0.0.244
[   29.662595] wlcore: firmware booted (Rev 8.9.0.0.84)

Also, the default wlan0 interface should be up once login is complete. 

root@am335x-evm:~# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 0C:1C:57:BB:60:5E
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
root@am335x-evm:~#

The above steps confirms that the driver is up and running.
