Tool/software: Linux
Hello,
I am using TI gel script to init both of ARM and DSP core on AM5716. DSP uses TI rtos, and ARM core uses linux. The script I used are: AM571x_dsp_startup.gel I see it basically just do a memory init. and it works fine when I download my dsp build using emulator.
In our real application, the DSP build will be loaded by linux core in ARM core. To my understand, the memory init should be done before DSP build is loaded to DSP core? if so, memory init job as following code in script: has to be done by linux kernel before it load DSP up?
