when i use MC56F84789, i program code of DAC output, and waveform is sine. if i debug the program through OSJTAG, the program runs well. but when I power down the chip and then power up, the DAC of DSC cannot output right wave.
I try other form of wave, like sawtooth wave, code runs well with OSJTAG or without it. i dont know why the code of sine-wave-output cannot run without OSJTAG.
