F2808 flash programming problem

Ivan Micovic

Hi,

I have been using Spectrum Digital XDS510PP debugger with CCS4 to program F2808 device. All examples that run from RAM work perfectly, so as a project of mine.

However, when I tried to run flash example, in console box message was repeating: "Target did not halt properly during flash operation", during attempt to erase flash sectors.

I had followed the instructions from http://e2e.ti.com/forums/p/12274/50820.aspx#50820, installed update 4.0.2.01003, and flash programming patch 4.0.3.

Now when I try to run the same example, I get this:

Error connecting to the target:
Error 0x80000220/-1156
Fatal Error during: Execution, OCS,
Lost processor clock. Device may be operating
in a low-power mode.  Do you want to bring it
out of this mode?

 

Any help would be appreciated.

    Hello,

    I have the delfino experimenter kit and i had the same problem.

    I think that the reason of this problem is the source code of the user. may be it functions in some way that provocate

    unexpected behaviour of the processor. So if the source code is loaded in flash memory, on power up, the processor executes the "bad code" and go to undetermined state.

    So, the emulator will not be able to communicate with the processor in this state.

    any way, the solution is to make the processor escape executing the "bad code" by booting from another memory where is located this bad code. in my case the flash memory.

    so I configured boot options to be from RAM and i turned off and then on the board and then Emulator could communicate this time with processor !!!! great
