VAYU M2M Capes

SW Images and Drivers

We provide active support for Debian Wheezy for all our capes. We are actively developing Android and Angstrom support and notes for these will also be here soon. To get started with our capes, you can take any of these paths:

Operating Systems supported (Debian, Ubuntu, Angstrom, Android)

We have tested the VAYU capes in the following configurations on different operating systems:

• Debian Wheezy: We provide full support for this. Pre-compiled images for both SD Card based use and for flashing to the eMMC are provided (see Section above).
• Ubuntu: We have tested our capes on Ubuntu. GPS (NMEA over serial tty port) is known to be working, PPS requires PPS support to be compiled in the kernel. The 3G modem (of the 3GH* and 3GC* capes) as well as the 2G modem (of the 2GD* and 2GQ* capes) have been tested to work on Ubuntu. We are in the process of generating Ubuntu images and making all configuration files available online.
• Angstrom: See Click Here.
• Android: We've been able to partially test our cape. Again, there are no known issues but we will put images and configuration files after fully verifying them.
