cc3000 buildtest initialization fails

[spicybrains]

When I connect my arduino (a Mega 2560) and launch buildtest, it gets stuck at initializing the CC3000. Digging into the drivers, it appears as though there's some sort of issue with the hci handler.

My configuration:

Code: Select all

// These are the interrupt and control pins
#define ADAFRUIT_CC3000_IRQ   3  // MUST be an interrupt pin!
// These can be any two pins
#define ADAFRUIT_CC3000_VBAT  48
#define ADAFRUIT_CC3000_CS      49
// Use hardware SPI for the remaining pins
// On an UNO, SCK = 13, MISO = 12, and MOSI = 11
// On a MEGA, SCK = 52, MISO = 50, and MOSI = 51

Wiring:
the cc3000 breakout circuit, on a prototype board
overall arduino
closeup, pins 48 to 52



The output from my Mega2560:

Code: Select all

Hello, CC3000!

RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 6374

Initialising the CC3000 ...
- starting WLAN
- init WLAN
-- init spi
-- checking irq
-- enable wlan en
-- wait till the IRQ line goes low
-- simple link start
--- u8 to stream
--- hci command send
--- simple link wait
---- hci handler
---- hci handler init

Any help in getting this to the point of connecting would be most appreciated.


ETA: it worked a few days ago, after I transferred it to the prototype board, and I didn't change anything when it started failing here. I did move the interrupt pin back to 3, on the offchance that my 19 pin (also an interrupt) got damaged.

I can't tell from the picture - are all of those jumpers soldered to the proto board?
