Improving Download Speed

[amspurge]

Hello,

I am working on an application that is somewhat large and each time I upload to my Disco Board it is taking three to four minutes because all of the TouchGFX images are being re-generated and uploaded. Is there a way to only upload the code from XCUBE with the screens staying the same? This would greatly reduce my development time. 

Any help would be great. 

Thanks,
Alex

Yes it is possible to build your app so that content in the external memory is excluded. Make additional project configuration for this, like "Debug internal only" or "Release internal only". Search the forum, this has been asked before.

Which DISCO board, they make a few.

Yes, would help if ST have some more robust processes for incremental build/update

The devices with ST-LINK/V3 run a lot faster. USB 2.0 HS helps, with right ports and cables

Writing multiple megabytes of QSPI NOR FLASH can be quite involved.

Got any links you could share?

I’m using the STM32F769I-DISCO. We were able to get from 3 min to 1:15 min by adjusting the settings. The problem seems to be that it spends over a minute searching for the STLink/Device. Any thoughts?

Hello @amspurge ,

Do you use TouchGFX Designer to run on target (F6)? Or maybe you compile with another compiler (like STM32CubeIDE), and flash using STM32CubeProgrammer?

Please give more detail here.

As @Osman SOYKURT said, what is "it" here?

Are you unplugging the ST-Link after each use?

Do you get the same with non-TouchGFX projects?

Have you been able to move on with your issue?
