Hello

I am trying to build the default mmf2\_video\_example\_v1\_init , I followed instructions and made the changes , The software builds i am able to flash it, it boots and then freezes -

[Driver]: start auth to c4:27:28:fc:1f:07

[Driver]: auth success, start assoc  
[Driver]: listen\_interval: 10, bcn\_interval: 100  
[Driver]: listen\_interval: 10, bcn\_interval: 100

[Driver]: association success(res=5)

[Driver]: set pairwise key to hw: alg:4(WEP40-1 WEP104-5 TKIP-2 AES-4)

[Driver]: set group key to hw: alg:2(WEP40-1 WEP104-5 TKIP-2 AES-4) keyid:1  
(0) Scan: 1, Auth: 1, Assoc: 1, 4way: 1, connect: 1, reason: 0

Interface 0 IP address : 192.168.1.58  
[LwIP\_DHCP] dhcp offered\_t0\_lease: 86400  
init\_thread(59), Available heap 0x69810c0  
[Driver]: TSFValue = 1738357043293, tsf = 0, shift\_set= 0x8000, bcn int = 100

Not sure what is going on here , any tips on how to resolve. I tried clearing build/ and redoing but its the same.
