The APF51 Linux distribution can be found here: latest stable installation tarball from SourceForge
Current version
Currently (armadeus-5.3) default supported Linux version for APF51 is: 2.6.38.8.
Details concerning the drivers usage can be found below.
- NT = Not Tested
- NA = Not Available / Not possible
There is an ongoing work to have mainline vanilla kernels (3.x+) working on the APF51. Board is already mainlined in Linux sources. See How_to_use_vanilla_kernel_on_APF51 if you are interested.
