Resolved! Write/Read issues with HyperRAM S70KL1282 on OctoSPI2 (STM32H7A3)

I am currently ramping up a new project which has a HyperRAM installed (S70KL1282 - like in the example project of STM32H735G). With the help of this sample project code I can successfully write and read with memory mapped mode from the 16 MB RAM - b...

Resolved! STM32U5A5: PSRAM (4MB external RAM) via QSPI (OCTOSPI1) - for you

Not a question: just to share with you my experience and "tricks" to connect a QSPI PSRAM on STM32U5A5/STM32U575 and potentially other MCUs (from a FW point of view, not HW).BackgroundI want to extend my own PCB, STM32U5A5 (LQFP64) with an external R...

NOR Flash(external memory )- Status error

Hi all, I'm working on the NOR Flash via OSPI(using as QSPI) with the STM32U585 board. implementing this via filex and levelx, i have done all the configuration referring to the example provided by ST with the minor changes. I'm getting error in the ...

Resolved! OctoSPI Flash in memory mapped mode also used for application data

Hi,We have a customer board with STM32H735 and OctoSPI flash in memory mapped mode.Memory is used for TouchGfx elements and as external code memory.Now we should add a simple file system for saving some data on the board.Is it possible to use a file ...

Dear support I have a problem reading the data from the hyperram octal memory, can anyone help me please?

Memory mapped mode write sizes for PSRAM APS6408L on B-U858I-IOT02A Discovery Kit

@Alex - APMemory I am trying interface APS6408L on the B-U858I-IOT02A Discovery Kit in OSPI DTR memory mapped mode for both read and writes. The datasheet for APS6408L mentions that the page size for it is 1Kb. In the memory mapped mode, is it possi...

STM32H7R/S XSPI flash wirte when on XIP mode

Hi, I'm wondering if write and erase external flash menory can be done when XIP mode on the same external Octal-Flash?I read RM0477 Rev 4.pdf and it told not recommand to programm the flash in this mode, and indirect mode can do that.Since the MX66UW...

Resolved! STM32u585 Memory Mapped Read/write on B-U585I-IOT02A

While using memory mapped mode for APS6408L using STM32u585 on B-U585I-IOT02A, how is the row boundary crossing handled?* If I want to write across multiple Rows in memory mapped mode, do I need to handle this manually or is it automatically handled ...

Is IS25LP064D supported to work on STM32U5 series.

Hi, im trying to work on external Flash with filex and levelx, and the external flash chip is "IS25LP064D ". i was trying to configure the OSPI, in the memory type other than micron, macronix, AP memory and Macronix RAM. I'm not able to see any other...

Setting up HyperRAM S70KL1282 with STM32H735 issues

Hi,I'm trying to setup this new RAM chips on STM32H735 in OSPI/HyperRAM mode. The HW connection is the same as on ST STM32H735 devkit. I found a driver for similar chip S70KL1281 but there are some differences, e.g. in latencies, but generally S70KL1...
