if i put all dsp/bios all sections into DDR2,how to boot from flash? when we build a dsp/bios project ,as defalut,all sections direct to IRAM(tcf->system->mem->porperties(bios data/bios code/compiler sections)),howerver,when our project becomes biger and biger,we cannot put them into IRAM. now ,i put all sections into DDR2,but it can not boot from flash.

my IDE is ccs3.3&ccs4,my bios is "bios_5_31_02", board is evmdm6437,and my way of download is AIS format(hexAIS & genAIS.pl,i try them both). my test project is "DVSDK\dvsdk_1_01_00_15\psp_1_00_02_00\pspdrivers\system\dm6437\bios\dm6437_evm\src\video\sample\vpbe"

I very hope your answer,thanks!

because i use hexAIS, in the doc of "643x bootloader", it say that there is a "JUMP_CLOSE" which direct to the start address of application code. is IRAM as the default start address of application code? so when my sections direct to DDR,it failed.
