Hi,
my investigation show that :
1) If CC3000 dosen't perform falling edge on its IRQ you will never be able to load a new firmware or do a normal start
2) My XCC3000 are.....empty. No bootloader and no firmware (or they aren't functionnal).
The good SPI messages for init can be now found at http://processors.wiki.ti.com/index.php/CC3000_Host_Programming_Guide#CC3000_Init_Operation
Best regards.
