How do I set the memory when I use TouchGFX on stm32f429IG?

PKunK.1

If you set TouchGFX in the stm32f429IG setting, an error appears for the memory below. External SDRAM is in use, FMC setting is done.

We drew a background from TouchGFX and loaded that background, which resulted in the above problem in compilation.

I don't know which setting is wrong.

If there is a problem with SDRAM settings, does this error appear?

Who can help you solve this error?

Hello,

What IDE are you using ?

I believe you haven't modified your linker file to tell the compiler to link the framebuffer to the external RAM. Have a look at the F429-DISCO Application Template available on TouchGFX Designer for reference.

Thank you for your advice.

As you said, the above problem is being used well now because of the linker disconnected.

Happy New Year and wish you good health.
