The official OpenEmbedded/Yocto BSP layer for Altera SoCFPGA platforms

This layer works with poky and Angstrom

Please follow the recommended setup procedures of your OE distribution.

Choosing Kernel Versions

This layer has a few providers for the kernel. These are the linux-altera, linux-altera-ltsi, and linux-altera-ltsi-rt kernels. There are also linux-altera-dev and linux-altera-ltsi-dev kernels which follow the current development versions of those kernels.

To specify a linux-altera kernel, add the following to your conf/local.conf

PREFERRED_PROVIDER_virtual/kernel = "linux-altera"
PREFERRED_VERSION_linux-altera = "4.3%"

or for the linux-altera-ltsi kernel

PREFERRED_PROVIDER_virtual/kernel = "linux-altera-ltsi"
PREFERRED_VERSION_linux-alterai-ltsi = "3.10%"

Please note that older kernels will not compile with GCC 5+ and you will need to specify in your conf/local.conf to revert to older 4.9 toolchain.

Choosing Toolchain Versions

The default Toolchain for ARM in Angstrom is the linaro toolchain. To specify the use of this toolchain in Yocto add the following to conf/local.conf

GCCVERSION = "linaro-5.2"
SDKGCCVERSION = "linaro-5.2"
DEFAULTTUNE = "cortexa9hf-neon"

To use older kernels not supported by GCC 5+ you will need to use the 4.9 toolchain.

For Yocto: GCCVERSION = "linaro-4.9" SDKGCCVERSION = "linaro-4.9" DEFAULTTUNE = "cortexa9hf-neon"

For Angstrom:

ANGSTROM_GCC_VERSION_arm = "linaro-4.9%"
