Problems upgrading from 4.9.6 to 4.10.0

Hi @Martin KJELDSEN​ !

You usually support me with TouchGFX, this must be a simple one for you but I can't find the solution in the community.

I'm having an issue trying to update my project from TouchGFX 4.9.6 to 4.10. I get the build error:

undefined reference to `touchgfx::HAL::copyFBRegionToMemory(touchgfx::Rect, unsigned short*, unsigned long)'

I think it is because I miss the function copyFBRegionToMemory(touchgfx::Rect, unsigned short*, unsigned long) in \touchgfx\touchgfx\framework\source\touchgfx\hal\HAL.cpp. Where can I find the latest version of source code to update?

Hi @Sandy.Dahl​,

Back from vacation. There's just one version of 4.10.0 and the signature for copyFBRegionToMemory() hasn't changed.

Did you figure anything out while i was gone?

Hi Martin!

I didn't figure out why I got that error. I deleted the TouchGFX-lib (4.9.6) and added 4.10 again, and the error somehow didn't return! So the issue is solved.

Thanks!

Okay, that's great :)
