OESF Portables Forum _ Gemini PDA - Linux _ camera and fm radio chipset model

Posted by: galodoido Jun 10 2018, 08:57 AM

What is the camera and FM radio chipset model ? Maybe it is possible, if not already in the debian kernel, to compile it. No /dev/video0 and /dev/radio on the debian .
Thank you all.

Unfortunately it looks like Mediatek has not implemented the v4l interface. @see: https://ncrmnt.org/2013/03/19/theres-a-server-in-my-pocket/
For the X25/X27 this is most probably the same. Maybe we can look up how it is being done in SFOS, there the camera seems to be supported.

Thus getting the cameras to work will be quite hard...
