TI's OMAP3 SoC family contains an ARM Cortex-A8 core running +at ~600MHz. Additionally some family members contain a TMS320C64x+ DSP ~430MHz +and/or an Imagination SGX 2D/3D graphics processor and various other standard +peripherals. + +Currently the following boards are supported: + +* TI EVM [2] + +* Gumstix Overo [3] + +* TI/DigiKey BeagleBoard [4] + +Toolchain +========= + +While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile +with -march=armv5 to allow more compilers to work.
