Summary
|
||
|
|
=======
|
||
|
|
|
||
|
|
This README is about U-Boot support for TI's ARM 926EJS based family of SoCs.
|
||
|
|
These SOCs are used for cameras, video security and surveillance, DVR's, etc.
|
||
|
|
DaVinci SOC's comprise of DM644x, DM646x, DM35x and DM36x series of SOC's
|
||
|
|
Additionally there are some SOCs meant for the audio market which though have
|
||
|
|
an OMAP part number are very similar to the DaVinci series of SOC's
|
||
|
|
Additionally, some family members contain a TI DSP and/or graphics
|
||
|
|
co processors along with a host of other peripherals.
|
||
|
|
|
||
|
|
Currently the following boards are supported:
|
||
|
|

Bootloaders
|
||
|
|
===============
|
||
|
|
|
||
|
|
The DaVinci SOC's use 2 bootloaders. The low level initialization
|
||
|
|
is done by a UBL(user boot loader). The UBL is written to a NAND/NOR/SPI flash
|
||
|
|
by a programmer. During initial bootup, the ROM Bootloader reads the UBL
|
||
|
|
from a storage device and loads it into the IRAM. The UBL then loads the U-Boot
|
||
|
|
into the RAM.
|
||
|
|
The programmers and UBL are always released as part of any standard TI
|
||
|
|
software release associated with an SOC.
