STM32H7 Hyperram Write sequence not correct

Dear ST-community, im Niklas Diehm and currently working on a student project, developing a Formula Student racecar. This year, we want to build a new dashboard for the driver. Therefore, we want to use a STM32H725ZGT6 with an external Hyperram S70KL...

STM32H7B3I-DK OctoSPI Memory Mapped Mode disable/enable problem

I've created a project using STM32H7B3I-DK eval board with all settings default, unmodified, taken from TouchGFX. UI menu is working fine with some resources stored in OSPI Flash memory.Now I wish to store some data in this OSPI memory. The procedure...

Resolved! Help needed for tuning 64Mb HYPERRAM (S27KL0642DPBHI020) on STM32H735IGT6

I need help with configuring HYPERRAM for my STM32 on a custom PCB. The HYPERRAM pins are about 32mm away from the MCU pins.The HYPERRAM works, but I get strange flickering on the display even with static data in RAM which I think comes memory errors...

Resolved! STM32U5xx: QSPI and SPI3 in DMA mode - callback comes too early - for you

I have my OCTOSPI1 as QSPI working - in "indirect mode", now using DMA: it generates a very clean waveform (no gaps between words or bytes as in "polling mode", a smooth waveform).I use also OCTOSPI1 as a "regular SPI transmitter" (acting as SPI Tx)....

about Execute in place using dual quad spi

What I want to do is XIP with DUAL QUAD SPI.The environment is as follows.Use Board : nucleo l4r5ziIDE : Atollic TrueSTUDIO® for STM32, Built on Eclipse Neon.1a.(Version: 9.3.0)FLASH : W25Q64JVThe connection diagram of the board and FLASH is shown be...

Resolved! STM32U5A5: DCache as "memory"?

My question might sound "strange" for HW experts.My STM32U5A5 MCU has DCache (16KByte). Datasheet says: used when external memory is connected (e.g. NAND/NOR flash, OCTOSPI).DCache is not used for internal memory (when running from MCU flash or inter...

Resolved! STM32H747: PDM MIC voice/audio via network (VBAN) - for you

If you need an example, how to use PDM microphones (MICs) on STM32 MCU and how to bring the voice/sound via network to a host computer (PC) - here is my project:https://github.com/tjaekel/PortentaH7_VFR_CubeIDE Here is a YouTube video with a demonstr...

Resolved! FLASH data cannot be read as expected using Memory Mapped Mode

I would like to read external FLASH data using Memory Mapped mode, which is a function of OctoSPI.The environment is as follows. Use Board : nucleo l4r5ziIDE : Atollic TrueSTUDIO® for STM32, Built on Eclipse Neon.1a.(Version: 9.3.0)FLASH : W25Q64JV C...
