Rarely on power up I will get a console print out that stops at the WWD SoC intialization and it will not continue booting or running the application. To me it appears something hangs while initializing the WLAN core but I have not tracked anything down.

Console print on issue

Starting WICED vWiced_006.002.000.0072

Initialising LwIP v2.0.3

DHCP CLIENT hostname WICED IP

WWD SoC.43909 interface initializing with US/0  

Console print on normal boot

Hi:

     just a suggestion, recommend this newest WICED Version: Wiced_006.002.001.0002.

I met some hang on 006.002.000.0072 before, didn't remember  which application had the issue.

but after upgrading to 6.2.1.2 I didn't meet the issue again.

Then this is very strange.

I asked the changes between sdk-6.2.0.72 ~ sdk-6.2.1.2.

AFAICT, nothing mentioned the hang fixes for sdk-6.2.1.2.

Thanks, upgrade to 6.2.1 is in my short term road map.

This start up issue happens very rarely and i have not been able to reliably reproduce it.
