Request for Assistance with NCN5121 Demo Dimmer Project -Incompatible BCU version 07B0 (required 0705)

[Pavancherry12]

Dear PedPak,
I successfully downloaded the Demo Dimmer Project from your GitHub repository and uploaded the code into the NCN5121 device. However, while downloading the configuration using ETS, I encountered an error message indicating an "Incompatible BCU version 07B0 (required 0705)."

Could you please provide me with the 07B0 database file or guide me on how to resolve this issue? Your assistance in this matter would be greatly appreciated.

Thank you for your support.

Hi Pavancherry12, after downloading and checking the source code, there is a compiled macro definition as below in the file project.h in the folder demo_dimmer\src. If you could complied the project, looks like you could try to use the #define EIB_DEVICE_MODEL EIB_DEVICE_MODEL_07B0. Let me know if any progress.
`/**
This onstant defines the KNX device model
possible definitions are (not complete):

• #define EIB_DEVICE_MODEL @ref EIB_DEVICE_MODEL_0705
• #define EIB_DEVICE_MODEL @ref EIB_DEVICE_MODEL_5705
  */
  //#define EIB_DEVICE_MODEL EIB_DEVICE_MODEL_07B0
  #define EIB_DEVICE_MODEL EIB_DEVICE_MODEL_0705`

Hi Betamoojw,

Thank you for your suggestion. You were right—I used EIB_DEVICE_MODEL EIB_DEVICE_MODEL_07B0 because my device model is 07B0. I modified the code accordingly. However, I noticed that the demo_dimmer.knprod database file is version 0705, which is not the version I need (07B0). Could you please share 07B0 database file or help me resolve this issue?Thank you.

Hi Betamoojw,Can you tell me how to modify the code to make compatible with 0705 version database or can you share me 07B0 version database file ?Thank You

demo_dimmer.knprod

Only Test Project DemoDimmer_0705.pr5 is found after downloading and unzipping the repo. Where did you locate the demo_dimmer.knprod? Let me check it and see if we could modify it if you can share me this demo_dimmer.knprod file.

HI,Try to download KAIstack_DEMO_STM32_GCC file and open demo_dimmer ,you may find that file,I think in this site I'am unable to share that file because that file is not showing in that folder while uploading here,Thank You

I believe I have downloaded and unzipped the file per your instructions. You may notice that the Test Project DemoDimmer_0705.pr5 ends with postfix .pr5 if enable to show file extensions on your computer. The file ends with .prj is a KNX project file (not a KNX product database file). It is difficult to modify KNX project file to get the KNX production database file.

I was wondering where you get the demo_dimmer.knprod database file. The plan is to try to modify this file. You could unzip it and check for further exploration.

[Pavancherry12]

you can also find demo_dimmer .knxproj file in this github also(TestRepo),both tapko and this .knxproj files belongs to same version
link.unzip this demo_dimmer.rar and you can see ETS_DB folder inside it and you can find .knxprod file there.Thank You.

Hi Pavancherry12, unfortunately the file ends with .knxprod is still not found. Looks like we have different version source. It will be helpful to read and understand these pdf instructions. Furthermore officially it is required to use the KNX Manufacturer Tool to create/generate/modify the KNX product database file.

[Pavancherry12]

Sure I will read those pdfs and Thanks a lot for your time and valuable information.

Hi @betamoojw ,I need a help to configure individual address of KNX device dynamically from ETS without hardcoding like EX:/** defines the individual address of the KNX device
*/
#define KNX_DEF_INDIVIDUAL_ADDR EIB_ADDR(0x1508)
can you guide me how to implement this functionality?for reference check C:\KAIstack_GCC_ON\appl_example\4in4out_07B0\src\cotab.h file
