STM32F429 DISCO board use SDRAM for PNG support

trial · Jun 7th 2018, 10:54am

Hello,
i want to display a png file on STM32F429 DISCO board, but i have no enougth memory in internal RAL. So i want to use the external 64-Mbit SDRAM for that.
It seems that i have to change the .ld file and refer to it in conf file.

What is the value to put in .ld file ?
Have you an example for that ?
Hoping for help
Thanks

Hi,

On the STM32F429 Discovery board the SDRAM starts at 0xD0000000.
I'm not sure what exactly you should add to your .ld file.

You could try out our eval package for this board, it includes a lot of our middleware and is configured ready to use.

All you need is Embedded Studio which can also be downloaded for free.
