STM32H723 - Problem with Serial RAM in memory mapped mode
Hi everyone,I’m testing a 32Mb serial QUAD SPI RAM (ISSI – ISS66WVS4M8) with the nucleo – H723ZG development board.It works fine if I use all the QUAD SPI commands but my need is to use it in memory mapped mode.When i use the memory mapped mode confi...
MDMA write error writing to DMA registers
Hello, I have a DMA stream working in Normal mode (Mem to Peripheral). This by itself is working properly (without MDMA). I want to configure MDMA to set the next parameters for the DMA to handle. I configure 4 words (4 uint_32) in memory for writing...
STM32l496: Clocking timer using LSCO
Hi, I wanted to clock my timer output using LSE crystal, but unfortunately only tim2 is supported with this feature. But then I saw an option of LSCO as output in cubemx, this enables the pin on MCU and according to documentation this output LSE cloc...
Resolved! Disable Flash ECC NMI Issue
Hello,I am currently developing a Bootloader for a STM32H562. The Bootloader checks, if there is a valid application present by calculating a checksum over the application area. To avoid getting ECC errors during the checksum calculation, I disable t...
what are the MDMA setting for OCTOSPI
Those are the setting for STM32H7A3IIT6Q ? (there is AN5050 where they show but DMA setting only)I am trying to useHAL_OSPI_Transmit_DMA(&hospi2, aTxBuffer)(I have this chip working in interrupt mode fine , HAL_OSPI_Transmit_IT(&hospi2, aTxBuffer) b...
STM32H7: no execution from flash while erasing or programming
Heyho,I'm currently working on an ethernet bootloader, I have it all working now.File upload via browser using http POST, into HyperRAM (~200 ms for 400kB bin file),from HyperRAM to external SPI flash (for now octal on H735-Discovery, later changed t...

STM32H7 QSPI in normal SPI mode for interface external DAC
My only need is to use QSPI (dual mode bank1) as a simple/normal SPI to drive external DAC (AD5066). I should only use the Data phase, I don't need the Instruction, Address, Alt and Dummy phases of the QSPI.I have to use:QUADSPI_CLK---> DAC_CLKQUADS...
recording audio with pdm microphone using SAI + PDM Interface
Hello, does anyone have any simple code for interfacing a digital microphone with the Serial audio interface? The MEMSMIC1 example project seems too complicated to start with. I am using the stmwb55rg nucleo board
