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. - -Environment Variables -===================== - -The DA850 EVM allows the user to specify the maximum cpu clock allowed by the -silicon, in Hz, via an environment variable "maxcpuclk". - -The maximum clock rate allowed depends on the silicon populated on the EVM. -Please make sure you understand the restrictions placed on this clock in the -device specific datasheet before setting up this variable. This information is -passed to the Linux kernel using the ATAG_REVISION atag. - -If "maxcpuclk" is not defined, the configuration CONFIG_DA850_EVM_MAX_CPU_CLK -is used to obtain this information. - -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=203&osCsid=c499af6087317f11b3da19b4e8f1af32 - -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=192&osCsid=67c20335668ffc57cb35727106eb24b1 - -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=222 - -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 - -7) TI DA850 EVM -http://focus.ti.com/docs/prod/folders/print/omap-l138.html -http://www.logicpd.com/products/development-kits/zoom-omap-l138-evm-development-kit |
