Dear sir,i have a problem in flashing of my dsp processor tms320f28335. i cant use flash memory for loading the code but in same time  i can load my code through ram memory . when i am loading my code through ccsv7  it shows the below error. Plz give me some suggestions for clearing this issue.

C28xx: Error occurred during flash operation: Timed out waiting for target to halt while executing FlashAPIInterface28335V2_10.out
C28xx: Can't Run Target CPU: (Error -1041 @ 0x429) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 7.0.100.1)
C28xx: Trouble Reading Register PC: (Error -1156 @ 0x0) Device may be operating in low-power mode. Do you want to bring it out of this mode? Choose 'Yes' to force the device to wake up and retry the operation. Choose 'No' to retry the operation without waking the device. (Emulation package 7.0.100.1)
C28xx: Failed CPU Reset: (Error -1140 @ 0x0) Lost debug connection to device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 7.0.100.1)
C28xx: Error occurred during flash operation: CPU Reset error. Error code 1

    Hi Afzal,

    Can you quickly try loading the flash based sample code? Following example:

    C:\ti\controlSUITE\device_support\f2833x\v142\DSP2833x_examples_ccsv5\flash_f28335

    Do share your observation.

    Regards,

    Gautam

    Afzal,

    If this is a unique problem to this device only, can you check to make sure that the CSM Passwords are still erased?

    http://www.ti.com/lit/ds/symlink/tms320f28335.pdf

    If these are not all 0xFFFF, then there is a programmed password that will need to be written back to the device to allow flash programming.  Assuming this wasn't intentional did you have a power fault while trying to program this particular 

    Best,
