Hello Swaminathan,

We are the team at IIT-Madras trying to port Genode on imx6. We are currently trying to create a shell for Genode natively. Towards this end, we would like to create a native keyboard driver on Genode. It would be great if you could give us a few tips to getting started on it.

assuming that you want to connect an USB keyboard, you will need a USB driver. In the 'repos/dde_linux' repository, you can find a USB stack ported from Linux. Currently, the driver supports the Pandaboard (OMAP4), the Arndale board (Exynos5), the Raspberry Pi, and x86 PC hardware. To use it on i.MX6, you will need to add the corresponding support code for the host controller as present in the i.MX6 SoC.

The details vary a lot between the different SoCs. E.g., for the Raspberry Pi, I had to integrate the dwc_otg driver using a separate repository because this driver is not present in the vanilla Linux kernel. I'm afraid that i.MX6 puts you in a similar position: You will need to extract the driver i.MX6-specific driver code from a vendor kernel.

Alternatively, you may have a look into other USB-driver implementations that support i.MX6 and port such a driver to Genode.

Best regards Norman
