cc3000_hostdriver_mbedsocket combined with SDFileSystem not working
Hi mbed-friends,
If I only use SDFileSystem or cc3000_hostdriver_mbedsocket in a project, they work, so the configurations seems right for each. But if I use them together in the same project it doesn't work. It does not matter if they share the same SPI bus or use different SPI busses.
I use a Adafruit Wifi Shield (cc3000) which also has an SD card slot on it used on SPI1. The platform is an Seeed Arch Max, which also has an SD card slot on SPI2. I tested cc3000_hostdriver_mbedsocket in together with either SD card slot (SPI1 or SPI2).
Has anybody been successful to let both libraries work in one project? Any help is much appreciated. I will also try to print more information to debug it.

Be the first to answer this question.
I haven't tested this. We know cc3000 is sensitive to timing so there might be a problem there (my initial guess). If you pinpoint the problem, please share.
posted by Martin Kojtal 02 Sep 2015Thanks Martin. Time is limiting me at the moment, hence I postponed narrowing down the problem, a bit. I would best start trying other platforms.
