CCS/TMS320F28377D: Low Power Mode Error

Hi, I have problems with programming my DSP, TMS320F28377D. I am having an error telling me the DSP runs in low power mode which I dont intent to do so. I was using TMS320F28379D (LAUNCH pad) and the code was OK. everything was running smooth . Now I am trying TMS320F28377D. I built my own circuit and I am using an XDS200 emultor. Changed my target configurations.  TMS320F28377D can be detected, no problem with that. However, while programming, it shows an error telling the device is in Low power mode. I checked my power supplies. Both 3.3 and 1.2 volts are ok. I have ADC reference voltages 3.0V. And all my libraries are designed for TMS320F2837x series. So I am thinking the code should be fine. I also have the GPIO41 pulled down which is done so in launchpad too. So what would you think the problem is? Any idea or suggestion is appreciated.
