Hi,
I have a touchGFX V4.23.2 project written with CubeIDE at least four IDE versions ago and have not had any upgrade problems until I upgraded from 1.17.0 to 1.18.0.
When I do a clean build I end up with memory link assignment errors:
When I do a build using 1.17.0 of the IDE i get an error free compilation and the project runs fine on the target.
I have checked that the build using 1.18.0 is using the correct linker script and that is OK.
I also checked the section attributes on the variable that go into the external ram and flash.
I note that a new version of gcc has been included, (Updated to GCC 13 as default toolchain) maybe there is a problem with that.
Any ideas on this?
My linker script is shown below.
