Hi,
I am doing a aduio processing test using Logic PD eXperiments kit.(OMAP-L138) the demoe code works fine the code is load on L2 memory, but did not work if it is loaded on external memory(DDR2). below are the two .cmd files I used. the first works fine. with second .cmd(.text on DDR), program did not start(not pointing to _c_init() although I can see _c_init() is at the location( 0xC0000000 in my case).
------------------------------------------

dsp_l2_ram: ORIGIN = 0x11800000 LENGTH = 0x00040000

shared_ram: ORIGIN = 0x80010100 LENGTH = 0x0000FF00
external_ram: ORIGIN = 0xC0000000 LENGTH = 0x08000000

}
