WL1805MOD: Crash issue during long time running

Part Number: WL1805MOD
Other Parts Discussed in Thread: WL1271

Hi experts,

Environment:

Use WL1805 to provide WIFI solution.

Linux version: Yocto-4.9.11.

Firmware version:

wlcore: PHY firmware version: Rev 8.2.0.0.240

wlcore: firmware booted (Rev 8.9.0.0.75)

Scenarios:

  1. Start wifi, provide ap service and stop wifi.
  2. Make it longtime working.

 

Issues:

  1. During test wifi Long-Time working, the wifi module crash sometimes in less than 12 hours, 2 related traces attached.

Other issues need your suggestions,

  1. If we not power off wifi chip, run ap_stop and ap_start again, the kernel will crash.
  2. If we run ap_start twice, the wifi will stop work.
  3. If we move attached station out of the wifi signal covered zone, and after hours, we move back, the station can attach wifi but no IP received.
  • Hi,
    - can you pls re-test with latest firmware ? git.ti.com/.../wl18xx_fw
    - pls confirm 'ifconfig wlan0 up" , 'ifconfig wlan0 down", 'ifconfig wlan0 up" seq works ok

    Saurabh
  • Hi Saurabh,

    We will try with the latest firmware. Before that, it will crash when execute your mentioned commands.

  • Hi, Please make sure WLAN_EN is getting de-asserted/asserted b/w ifconfig wlan0 down/up. Thanks
  • Hi

    It use FPGA to control WLAN_EN. So, it’s why we must use another script to power down WL1805. Seems it is a trouble maker.
