DSPS size

Hi dialog support team,

I'm using Keil uV5 to build the firmware, if I set the optimization -o0, the built firmware sps_device_580.hex(what is your binary image?) is 77Kb, and if I use -o3 the firmware sps_device_580.hex is 52Kb, and I can not get 25Kb or even 15Kb as in the above link indicates.

Can you have a look of the attached, may be there could be improvement of optimization seeting to downsize the firmware?

Or you use other tool to build the firmware?

My DSPS version is DA1458x_DSPS_v_5.150.2, I tested ..DSPS_v_5.150.2\projects\target_apps\dsps\sps_device\Keil_5\sps_device.uvprojx, and I did not do any modification.

Thanks

Hi dialog support team,

If I setUse Cross-Module Optimization, I can't create .Hex, it is said I need to compile twice, but still can't created the firmware.

The output as following:

compiling user_spss_task.c...
compiling user_buffer.c...
linking...
Program Size: Code=16152 RO-data=2420 RW-data=72 ZI-data=10200
".\out_580\sps_device_580.axf" - 0 Errors, 1 Warning(s).

*** Performing Cross-Module-Optimization:
*** Feedback file '.\out_580\sps_device_580.fed' not found.
Target not created

Thanks a lot

Hi dialog support team,

Do you use command Line to build the firmware?

If yes, as I never used commandline to build,can you help to give an example ?

Thanks

Benjamin

Dear Dialog,

I checked the images, the settings are the same.(In the target tab, I also set Use Cross-Module Optimization )
My Keil IDE version is 5.1x, I will update to version 5.26.2.0 if everything is done while still can not solve the problem.
About Keil modification, I installed ARM.CMSIS.5.1.1.pack, I wonder if the pack is the reason why I can not build .Hex.
Yesterday I tried to build a project with SDK 3.x, and I succeeded even if I set Use Cross-Module Optimization , is there any difference between SDK3.x and SDK5.x that can be the reason?
I downloaded DSPS again and still can not build .Hex if I set Use Cross-Module Optimization in the target tab.(I can build without set Use Cross-Module Optimization,but the firmware is bigger than 42Kb)

Maybe Windows(Win7) setting? In mycomputer-(right click)-property-advanced system seetings-Environment Variables, do you have any special settings for user variables or System variables?

Thanks

Hi dialog,

Transferred my project from SDK3.x to SDK5.x, and I will not go back, I simply to have different try to compare.

Can you please tell me the difference between 3.x and 5.x that might come to the different compile result?

I downloaded DSPS again, but the result is the same.

Benjamin

Hi Dialog,

The newly downloaded project can't be compiled successfully if I setUse Cross-Module Optimizationin the Target tab. I need to change the Misc controls in the Linker tab from --feedback=".unused.txt" to --feedback=".\out_580\sps_device_580.fed", and it can be compiled.but still the .HEX is big than expected.

Can you help to have a look of all the settings in the attached. and compare with yours to find out the difference?

Or can you help to give your seetings to me for me to compare?

maybe the reason is in the settings.

Thanks

Benjamin.

Hi dialog,

你设置使用跨模块优化吗?

If I do not set it , the firmware is big.

Benjamin

Hi dialog,

Did you build the project immediately without any setting and you got the firmware less than 42 kb?

Thanks

Benjamin
