Re: [Xenomai] Simple application for invoking rtdm driver

[Pintu Kumar <pintu.ping@gmail.com>]

Hi,

Any clue on this?

I guess native and alchemy skin is internally same.
Then why rt_dev_xxx does not work with alchemy skin.
Please let me know the alternate API to invoke rtdm driver with alchemy skin.

Thanks,
Pintu
