Hi, I am new to this group and would appreciate assistance in how to use a device which has an ARM cpu and Mali400 gpu for the purpose of sending CEC commands via pin 13 of the HDMI port of my device.
I understand that the Mali400 "supports" CEC but expect to utilize this feature I would need to download a special driver or library.
Any advice or direction is very much appreciated.
Mali-400 is only the 3D GPU block in the chip. ARM licenses the Mali-400 design to other companies, who then add their own parts like the HDMI controllers and turn into a real silicon chip. The HDMI controller is outside of the GPU, so you will need to check with your chip vendor to see what is possible there.
Sorry I can't be more help,
Pete
