Hi Aarti!

Ive followed your advice from the your answer to the post:

After i pressed Run from the debug session, I enabled the real time mode, but the same error message flashed from the console window:

C28xx: Trouble Writing Register ST1: (Error -2012 @ 0x6) Requested operation cannot be done while device is running. Halt the device, and retry the operation. (Release 5.0.333.0)
C28xx: GEL: Error while executing OnTargetConnect(): target access failed.
C28xx: Failed Software Reset: (Error -1138 @ 0x0) Device refused to allow debug mode. Power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Release 5.0.333.0)
C28xx: Failed Software Reset: (Error -1138 @ 0x0) Device refused to allow debug mode. Power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Release 5.0.333.0)

Please help! Thanks!

Cyrus,

Try  enabling real-time mode after establishing connection to target but before running/debugging. Basically start the debug session, enable real-time mode when target is halted and then run the code. Let us know if this sequence fails as well.

Hi Aarti!

There is another error when i connected to the target. the following messages appeared from a dialog box:

Error connecting to the target:
(Error -151 @ 0x0)
This utility failed to open the adapter for a custom emulator.
The adapter returned an error.
(Release 5.0.333.0)

Thanks!

Hi Cyrus,

There is another thread with people reporting the same issue. Some have got it working now.
