John in older similar processors(omapk178) to halt ( not sure about disabling) DSP we poked a value in a register from ARM side before calling the RTOS not sure where this needs to be done in Linux our code wasn't in user space.The TRM and maybe some sample code will point you to the register and hopefully a description of freeing up that DSP memory. Typically a gel script needs to do the same thing when loading either core over JTAG but it's doubtful finding that scriptwill be easy. Mark
