STM32N6 FMC SDRAM: what does "Primary interfaces used" mean, and which pins are the primary ones?

Hello, We are designing a board with STM32N647X0H3Q (VFBGA264) and a 16-bit SDR SDRAM (512 Mbit, x16, 3.3 V LVTTL) on the FMC, and we would like to run SDCLK at 133 MHz and 166 MHz. In DS14791 Rev 10, section "SDRAM waveforms and timings", the

STM32N657 revision B: NRST workaround without an initial software reset?

Hello,Our STM32N657 appears to be revision B. We use a battery-powered board with an STM6601 power-button controller. The MCU asserts PSHOLD early in the FSBL to keep power enabled.ES0620, section 2.2.18 specifies setting SYSCFG_CM55RSTCR.CORE_RESET_

VL53L9 software package for low resource microcontroler ?

Hi, I’m trying to use a VL53L9 with a microcontroller which have 128kB of RAM. For this I use the STM32CubeExpansion_53L9A1_V1.0.0 package. The problem is the streaming library delivered within the package is not made for low RAM usage. It’s stack us

STM32H757 system bootloader (SPI2) never sends ACK

SummaryWe program a slave STM32H757 through its system bootloader over SPI (AN4286), driven by a second STM32H757 acting as SPI master. About 20 % of our production boards cannot be programmed: after the 0x5A synchronization byte, the bootloader ret
