When running Debugger on DVP3 with STVD7 on a ST72321AR6, I get no I2C running. Looking in MCU Configuration, I see there is no I2C defined from 0x18 to 0x1E in the Config map.

Is there any way I could be able to config that MCU for I2C running ?

Thanks

Hello,

It seems that you are right, the I2C registers are correctly defined in the SFR descriptions but the memory area is declared as NEM (Non Existant Memory) in the maping. The error exists for the st72321 (A)R6, st72521 (A)R6, st72521 B(A)R6.

The error does not exists on the EMU3. This will be fixed in the next release of STVD7.

Opening the mdb file in ..\dvp3\config and correcting the appropriate lines in the memory area map table would probably correct the problem.

Be aware that any change to the files of STVD7 after installation can cause severe problems and can be done only at your own risks.
