Hi, Margarita
thanks for your reply!

Is the operatint on dm8168' c674x same as on TMS320C674x?

i'm using tms320dm8168, and using it's dsp core(c674x) , not TMS320C674x.
on dm8168' c674x, L2RAM has only 256KB.

Hello,

I am sorry my misunderstanding. Let me check .

 The DSP subsystem on DM8168 includes TI’s standard TMS320C674x megamodule.

My operation is according to http://e2e.ti.com/support/embedded/linux/f/354/p/202453/904792#904792.
define one section "DSP_L2" , then put the code to "DSP_L2".
