Yocto 1.5 with FTDI - CGTQMX6

[joshcollins]

I have successfully built the 'fsl-image-gui' image and installed it on my cqtqmx6. I require FTDI drivers to be installed to detect a usb device as a serial port. I am unsure how to go about adding these drivers. I have tried modifying my local.conf file with the following line:

PACKAGECONFIG_append_pn = " libftdi"

which didn't seem to do anything. I also tried:

IMAGE_INSTALL_append = " libftdi"

Which caused bitbake to fail with the error: "ERROR: QA Issue: libftdi: The compile log indicates that host include and/or library paths were used."

I don't have a great understanding of knowing how to add more features to my yocto image, and would appreciate any help with enabling FTDI support.

Cheers,

Josh

Hi Josh,

in order to enable the driver on the Linux Kernel you can change the defconfig file with:

CONFIG_USB_SERIAL=y

CONFIG_USB_SERIAL_FTDI_SIO=y

Thanks Alex! I had just discovered this myself, it was exactly what I needed!

Cheers,

Hi Josh,

Although FTDI devices are enumerated as Virtual COM Ports, they usually have a custom driver instead of the standard CDC driver. So, you could ask to FTDI if they provide such driver.

Hope this will be useful for you.

Best regards!
