New art & good vibes: Acuarela, Fabrica. This application note describes the use of the STM32L476/486 FSMC (flexible static memory controller) peripheral to drive a set of external memories. Thus, we need to set up the DIVM2 and PLL2 "N" multiplier, "R" and the divider right after the output of the PLL2 in a way to get 200MHz to the FMC. You can find this basic layout in the first two sections of the reference manual‘s “Flexible Memory Controller (FMC)” chapter. The BootROM use case is intended to demonstrate how to boot from the internal Flash memory, configure the external RAM memories (SDRAM, SRAM or OSPI-RAM), copy user-application binary from the code storage area (an SDCARD or an SPI-Flash memory) to the external SDRAM, external SRAM or external OSPI-RAM, and then jump to the user application. in STM32 MCU products 2023-04-05; STM32H7 SDRAM IS42S16320F-7, Mem Viewer Works, But Code Generates Mem Access Violations in STM32CubeMX (MCU.

The OpenH743I-C is an STM32 development board with STM32H743IIT6 as the main controller chip, which comes with a rich expansion interface to support access to various peripheral modules. If the STM32CubeMX is configured for an 8 bit data bus, there is no DQM pin generated, although the 8 bit SDRAM has a DQM pin that needs to be connected somewhere. On page 5 it shows that MCU Bank 1 can use a 64M x 4 configuration. It is only 32 and 64-bit variable writes that cause a problem, where the values read afterwards return 0. As I understand, I have several options: Using SD-RAM with the Flexible Memory Controller (FMC) Using some other form, e PSRAM with the FMC.
