how to produce file awb_calc_data.c in TI 2A under dm365/368?

thanks you for our answer.  i use the awb tuning function in ImageTuningTool step by step, it procude some files in AWB_Tuning directory. such as TI_AWB_Calibration_Config.txt,3000_YUV_H3A_SELECTED.txt,3000_RGB_H3A_SELECTED.txt,3000_RGB_HIGH_RES.txt,3000_RGB_H3A.txt, etc.

 but no file awb_calc_data.c , when I use "AWB Send Parameter" send the parameters to IPNC , the software say "Error: AWB Send Parameters(AWB_Config.cfg) could not be found in c:\Program files\ImageTuningTool_DM36x\Program\AWB_Tuning".

the soft version is 2.2 , what's the error mean? how can i do?

thanks.

Can you please check if the file named "AWB_config_hardware.txt" is generated? the contents of this file are the one that are kept in awb_calc_data.c file.

Regrds,

Uday

thanks , I checked that there has no file AWB_config_hardware.txt . what's the matter?

Best Regards.

Looks like some problem with process of the tuning you have done.

Can you list all the files that tuning tool generated. 

Also please copy the contents of the file TI_AWB_Calibration_Config.txt. I will try to locate the problem.

Uday 

the files under awb_tuning directory are:

TI_AWB_Calibration_Config.txt,3000_YUV_H3A_SELECTED.txt,3000_RGB_H3A_SELECTED.txt,3000_RGB_HIGH_RES.txt,3000_RGB_H3A.txt,4000_YUV_H3A_SELECTED.txt,

Hi All,

I have the same problem with Alex. Could you please tell how to tackle this problem?

Thank you all!
