Hi everyone,I'm using a STM32F769BGT6 with an external SDRAM (IS42S32400F). This SDRAM is composed of 4 banks. Each bank contains 12 Rows (4096), 8 Columns (256), and each cell is 32 bits. So : 4096*256*32 = 33 554 432 bits, or 4MBytes/Bank. That mea...

Hi Clive,Ok I tested the DISCO code, with proper conf for my board, and the behaviour is exactly the same. It's working for 32 bit, but not for 8 bit.I updated the schematics from my previous post with more hi-res files, sorry about that. I noticed s...
Do i need to do something specific to have those BYTE LANES pins NBL[3:0] to properly mask data when I try to write bytes? I assume it is handled by the FMC, but maybe I have to use exclusively HAL methods to have it working?
