Hi guys,

i have a custom board on which both, LTDC and FMC conneted SDRAM, is used.

If I enable the burst access to the SDRAM the board crashes after a while. Assuming the accesses between SDRAM and LTDC are not handled properly. If I disable the burts access to sdram everything is fine.

 I tried also to set the SDRAM as shareable memory with the mpu.

I'm using the SDRAM for heap and framebuffer.

But no success with that.

Anyone an idea ?

Regards
