The source package provides the source code for the Linux BSP (kernel 3.7, U-Boot 2012.10), packages for the root file system, and the tool chain (Linaro GCC 4.7 HF). The BSP sources are built with Yocto/OpenEmbedded (Denzil). A pre-built Linaro tool chain is provided. The package of pre-built images provides binaries (pre-loader, U-Boot, kernel and RFS as well as an SD card image) that are ready to be used.

Known Issues

Issue#	Headline
103239	Intermittent loss of transmission with the STMMAC ethernet driver
117859	seq 10000 > /dev/LCD0 causes I2C to lose arbitration
118160	Tilda displays as small arrow on the Newhaven LCD
