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. + +Links +===== + +1) TI DaVinci DM355 EVM: +http://focus.ti.com/docs/prod/folders/print/tms320dm355.html +http://www.spectrumdigital.com/product_info.php?cPath=103&products_id=20... + +2) TI DaVinci DM365 EVM: +http://focus.ti.com/docs/prod/folders/print/tms320dm365.html?247SEM= +http://support.spectrumdigital.com/boards/evmdm365/revc/ + +3) DaVinci DM355 based leopard board +http://designsomething.org/leopardboard/default.aspx +http://www.spectrumdigital.com/product_info.php?cPath=103&products_id=19... + +4) TI DaVinci DM6467 EVM: +http://focus.ti.com/docs/prod/folders/print/tms320dm6467.html +http://support.spectrumdigital.com/boards/evmdm6467/revf/ + +5) TI DaVinci DM6446 EVM: +http://focus.ti.com/docs/prod/folders/print/tms320dm6446.html +http://www.spectrumdigital.com/product_info.php?cPath=103&products_id=22... + +6) TI DA830 EVM +http://focus.ti.com/apps/docs/gencontent.tsp?appId=1&contentId=52385 +http://www.spectrumdigital.com/product_info.php?cPath=37&products_id=214
