Versioning
Software
This BSP release supports various configurations of the phyBOARD-Mira i.MX6 SBC. You will need to know which Yocto machine configuration corresponds to your kit in order to build the appropriate BSP. By default, only the standard kit configurations are shown in the table. If you have a different kit, use the filters below to search by SBC part number or population. The barebox images and kernel device tree file names are important when creating custom Barebox and kernel images outside of Yocto development.
Linux Devicetree Summary
The following is an example describing the structure of the device tree for the standard phyBOARD Mira (machine configuration phyboard-mira-imx6-3).

BSP Features
The following table lists the interfaces available from the phyBOARD-Mira.
- Implemented - driver support exists in the kernel.
- Tested - the interface has been configured in the device tree and was tested by PHYTEC
Enabled in DTS - the corresponding device tree nodes are enabled in the device tree imx6q-phytec-mira-rdk-nand.dts
The "Enabled in DTS" column is specifically for the standard phyBOARD-Mira (machine configuration phyboard-mira-imx6-3).
Please look at the dts file corresponding to your machine configuration for differences.
