CEC Linux Driver for SECO X86 Boards

Sources for SECO CEC Driver. Based on Linux CEC Framework.

Compatible with:

• UDOO X86 (all versions)

Compile

Make sure you have Linux kernel headers >= 4.10.

# install dependencies (make, git, ecc..)
sudo apt install git build-essential linux-headers-`uname -r`

# clone repo
git clone https://github.com/ektor5/secocec

# go to dir
cd secocec

# compile
make

The module should appear as seco-cec.ko.

Mount

This module depends on the Linux CEC Framework Module, and it needs to be loaded first.

modprobe cec

Note: this module conflicts with the official SMBus driver i2c-i802 and therefore it needs to be blacklisted. On Ubuntu should be already blacklisted.

echo "blacklist i2c-i802" > /etc/modprobe.d/i2c-i802.conf

Load the module:

insmod seco-cec.ko

Done!

Use

To test the device from userspace (/dev/cec0), there are several programs ready to use in v4l-utils tools package (available to install via apt):

• cec-ctl: An application to control cec devices
• cec-compliance: An application to verify remote CEC devices
• cec-follower: An application to emulate CEC followers

Check the corresponding man pages for info.

Debug

To compile the module with debug messages:

make DEBUG=1

Feel free to open issues or mail me directly. Make sure to include dmesg, lsmod, etc.. in the bug report.
