Summary
|
|
=======
|
|
|
|
This README is about U-Boot support for TI's ARM Cortex-A8 based OMAP3 [1]
|
|
family of SoCs. TI's OMAP3 SoC family contains an ARM Cortex-A8. Additionally,
|
|
some family members contain a TMS320C64x+ DSP and/or an Imagination SGX 2D/3D
|
|
graphics processor and various other standard peripherals.
|
|
|
|
Currently the following boards are supported:
|
|
|
|
* OMAP3530 BeagleBoard [2]
|
|
|
|
* Gumstix Overo [3]
|
|
|
|
* TI EVM [4]
|
|
|
|
* OpenPandora Ltd. Pandora [5]
|
|
|
|
* TI/Logic PD Zoom MDK [6]
|
|
|
|
Toolchain
|
|
=========
|
|
|
|
While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
|
|
with -march=armv5 to allow more compilers to work. For U-Boot code this has
|
|
no performance impact.
|
|
|
|
Build
|
|
=====
|
|
|
|
* BeagleBoard:
|
|
|
|
make omap3_beagle_config
|
|
make
|
|
|
|
* Gumstix Overo:
|
|
|
|
make omap3_overo_config
|
|
make
|
|
|
|
* TI EVM:
|
|
|
|
make omap3_evm_config
|
|
make
|
|
|
|
* Pandora:
|
|
|
|
make omap3_pandora_config
|
|
make
|
|
|
|
* Zoom MDK:
|
|
|
|
make omap3_zoom1_config
|
|
make
|
|
|
|
Custom commands
|
|
===============
|
|
|
|
To make U-Boot for OMAP3 support NAND device SW or HW ECC calculation, U-Boot
|
|
for OMAP3 supports custom user command
|
|
|
|
nandecc hw/sw
|
|
|
|
To be compatible with NAND drivers using SW ECC (e.g. kernel code)
|
|
|
|
nandecc sw
|
|
|
|
enables SW ECC calculation. HW ECC enabled with
|
|
|
|
nandecc hw
|
|
|
|
is typically used to write 2nd stage bootloader (known as 'x-loader') which is
|
|
executed by OMAP3's boot rom and therefore has to be written with HW ECC.
|
|
|
|

several TI employees.
