Robert, Sorry I can't help at the moment, too many other things to do! You have beaten me to doing a port for my LPC4357. The only comments I can make is make sure you are using the correct spi mode, and you have the interrupt and ISR working correctly. You just need to keep at it, running as much debug as you can. Keep posting and I will try and keep an eye on what you are doing.

Dave.

Robert, One more thing. It would be much easier to first write an spi driver and test it on something other than the CC3000, so that you are confident that it works. Otherwise you may well lose a lot of sleep trying to put bits into the CC3000 drive and finding they don't work.

Dave.

Accidentally I added an answer instead of comment, how can I delete that?

just to be on the same line , this is not related to mbed , neither to cc3000 host driver shared on mbed ?

Martin, Correct! Robert appears to be porting C code to his LPC4337, not mbed related. If Micromint get their board across to mbed, then it might be related.

Dave.

Hi Dave, I just made an earlier port, I achieved a connection to my router, unfortunately I couldn't get the DMA work, but I will keep trying. The other problem was the DEBUGOUT function, when I used in the code sometimes I got HardFault. I am using FREERTOS, should I use semaphores to avoid such a problem?

Regards, Robert

Robert, Using an OS is not going to be easy. I don't know of anyone who has gone that yet! Due to the original TI C code using blocking methods, you would need to change that to polling. You will need to take special care with the CC3000 interrupt. Using semaphores would be one way.

Dave.
