Other Parts Discussed in Thread: TMS320F2812

Dear Sir/Madam,

Greetings of the day!!!!

I am final year student from VNIT,Nagpur, India. Currently doing my project based on TMS320F2812. Also I am using ezDSP from texas. I am having following problem while connecting to the kit.

Error Code: 1166

Error Class: 0x8000224

Error during:

Register, Execution,

Lost processor clock. Device may be operating in a low-power mode.

Do you want to bring it out of this mode?

Please guide me to get rid of this problem.

    Hi Sakthi,

    Please check your target configuration settings. Check for whether the debugger and device selected are correct.

    Also, which CCS version are you using?

    Regards,

    I am using version 3.1

    target configuration, debugger and device selected are correct only

    I know three possible reasons for this error to occur.  

    1) External clock to the device is missing 

    2) One of the VDD or VDDIO rails are not powered

    3) Device is kept  in low power  mode using idle instruction

    If you have already checked the above three possibilities, then try to get rid of the "lost clock" message by lowering the JTAG - Clock from the default 1 MHz down to (some) 100 kHz..

    Regards,

    Thank you for your fast reply.

    I have changed any settings of eZDSP kit obtained from TI. It was running successfully for last one year.Yesterday suddenly some problem happened i do not know what happened

    Check for the voltage levels on the board then... Are they as per the schematics of the board? Touch the components and see whether any of the components are overheating?

    If possible please download the latest CCS v5.5; this will help us to check the status of your emulator too.

    How to test Voltage Levels on the board?

    Do you mean supply voltage?

    One IC (PS767D301) heats up lot.

    Also I do not have Jtag emulator.

    I am using Parallel port only hence I believe i can not connect to V5.5.

    How to test Voltage Levels on the board?

    Sakthi, if you check the schematics the voltages at different points would be mentioned. You can cross-check those voltages on the board.

    One IC (PS767D301) heats up lot.

    This is a LDO IC; do check the output and input voltage of this IC. (17,18) and (23,24) pins are the output pins; check whether 3.3V is available at the output and is properly fed to the F2812.

    One IC (PS767D301) heats up lot.

    That shouldn't happen. Check the voltages on it I/P and O/P pins.

    I am using Parallel port only hence I believe i can not connect to V5.5.

    No problem!

    Regards,
