DSK6455 CCS 4.2.3.00004 GEL Errors (Driver did not attempt to write memory at ...)

Hello Gents,

I have recently received a DSK6455 and I was trying to get proper communication with its on board emulator. I have everything working as a charm under CCS 3.3 so I can rule out the hardware failure here.

I have created a new target using "Target" menu and then "New Target Configuration ...". I have named the configuration file "dsk6455.ccxml" and saved it to a shared location ("Use shared location" checked). Then I choosed "Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator" as connection and checked "DSK6455". In the advanced tab I could see DSK6455 GEL is selected abd the GEL file selected seems to be the correct one (C:\Program Files\Texas Instruments\ccsv4\emulation\boards\dsk6455\gel which is also the same one as on spectrum digital website).

From the "Target" menu I have chosen "Launch TI Debugger" and no specific errors are triggered. I can see the debugger attached to the embedded USB emulator.

Then still from the "Target" menu I have chosen "Connect Target" and I get the following errors to the console:

C64XP_0: GEL: Error while executing OnReset(0): Driver did not attempt to write memory at 0x02AC002C.

C64XP_0: GEL: Error while executing OnTargetConnect(): Driver did not attempt to read memory at 0xA0000004.

And a few seconds after (30-60 seconds):

C64XP_0: Power Failure on Target CPU

C64XP_0: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

Not sure if I do something obviously wrong here. I was thinking the problem is memory map related and placed some GEL_TextOut() around setting up the memory map and everything is fine!

Any help would be greatly welcome

Best Regards,

Arnaud
