Hello,I have a STM32H75x design and suffer from read errors in DDR timing, no matter if run at 50MHz or slower.It seems that the data hold time of 1ns the H7 is violated. The data output hold time of the SPI NOR MX25L12845 flash is 1ns, which seems t...
Hello everyone,I’m working on an STM32H7S3L8H6H with two XSPI interfaces:XSPI1 (Quad-SPI) connects to an external PSRAM. XSPI2 (Octo-SPI) drives an external NOR flash, from which my application code executes directly.In my bootloader I configure both...
Hi all,I am working on a QSPI driver for W25Q512 flash memory (extloader for stm32cubeprogrammer and main firmware driver). I had a look at the errata ES0392 - Rev 13 and I have a question about paragraph 2.8.4: 2.8.4 - QUADSPI internal timing critic...
Hello Support, I am not able to find the QSPI config in the STMCube 1.18.1version. I have attached the snapshot. According to the EvalBord it supports QSPI. CAN you guide me here for the setup. Best Reagrds, Manikanta
We are creating a driver for a W25Q128JV Winbond Nor Flash chip. We are working with a STM32 H743ZI2 board and communicating on the QSPI peripheral with the help of the HAL libraries. Currently the driver can successfully Write to the chip using stan...
We are currently using the STM32H723VGT6 MCU (1MB Flash) in our application.We would like to clarify whether this MCU supports execute-in-place (XIP) from Quad-SPI flash or if Octal-SPI is required for XIP functionality.In the future, if our applicat...
I am trying to communicate with an external flash chip “MX35LF1G24AD” using QSPI protocol, but I am not able to. Simple test I implemented was to read chip ID to validate I could get data from external flash (I am using OCTOSPI1 interface). From manu...
Hello, I am using QuadSPI in STM32H723ZGT6 which has OCTOSPI and I am changing octospi to quadspi in pin configuration and writing code also I had written same code for STM32H750VBT6 which only supports QUADSPI and I am using W25Q128JVSIQ Flash for t...
I am trying to debug some functions to write to the memory mapped QSPI. When I go to debug it, I notice that before any functions even run the QPSI is in HAL_QSPI_STATE_ERROR, therefore I cannot test my code to see if is running because it is depende...
Hello,I am attempting to set up QSPI to operate in classic SPI mode so that I can transmit data to another STM32 processor. I have set up my code as followed and have connected my QSPI lines to an oscilloscope and a half duplex SPI slave on the same ...
