CC3300: Driver compatibility and firmware upload

Tool/software:

Hello,

We want to use the CC3300 for a WiFi Application. We already have ported to driver and have it running with the CC3351. 

Unfortunately, when switching to the CC3300 our application do not work anymore and we get stuck at this point : 

// RAM Bootloader download
printf("wlan - download rambtlr....\r\n");
ContainerDownload("rambtlr");
  
if(FwEvent_wait( OSI_WAIT_FOREVER ,HINT_SECOND_LOADER_INIT_COMPLETE) == -1)
{
printf("wlan - didn't receive RAM init complete");
assert(0);
}

// RAM Bootloader download
printf("wlan - download rambtlr....\r\n");
ContainerDownload("rambtlr");
  
if(FwEvent_wait( OSI_WAIT_FOREVER ,HINT_SECOND_LOADER_INIT_COMPLETE) == -1)
{
printf("wlan - didn't receive RAM init complete");
assert(0);
}

the Ram bootloader seem to be uploading and the CC is responding but the process seem to fail at the end. The condition 

HINT_SECOND_LOADER_INIT_COMPLETE never append.

Is their something to configure in the driver ? Do we miss something ? Is the driver fully compatible with the entier familly ? 

Thank you for you help.
