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 ?
