In STM32CubeIDE, the NOR Flash seems to work fine that data was correct both by reading to variable and reading 0x90000000 of memory mapping address.But if terminate the session and restart and just read the data, it is all gone.And there is another ...
Hello,I'm implementing QSPI on STM32L451 with a NOR FLASH memory (Micron MT25QL512ABB, 64Mbytes) for the first time, using DMA, for the moment it seems to work, but I'm surprised by the timings.CPU runs at 16MHz, QSPI clock speed is 8MHz. For this ex...
A few days ago I successfully tested erasing the NORFlash as entire chip erase, block erase, and sector erase. I also was able to write a string to Flash and read the string back out of Flash into a buffer. After working on other development I came ...
Hi every one ..I designed custom board for stm32h745xit6 .My TouchGFX working fine with internal flash .The core board has mt25ql256a and connected as under PB2 CLKPG6 NCSPF8 D0PF9 D1PF7 D2PF6 D3I generated STLDR as explained in ST videos tutorial.my...
Hello,we are trying to flash the external NOR flash at address 0x90000000 with Openocd 2-times and get an error at the second flash try: Open On-Chip Debugger > program /home/xyz/kr.elf [stm32h750xbh6.cpu0] halted due to debug-request, current mode: ...
I'm using MX25V1635F on WB55Below, read/write functions work fine#define SECTOR_ERASE_CMD 0x20#define QUAD_IN_FAST_PROG_CMD 0x38But in memory mapping mode, only few bytes correctly or even nothing right,CS, SCLK work as expected but D0 seems like out...
I am using QUAD SPI in STM32H747 in dual mode. 2 x W25N01GV flash memory chips are connected. The problem is that the odd data (bank 1, flash 1) is written / read normally, and the data of the second bank (flash2) is shifted by 4 bytes (in the first ...
I want to read and write to w25q128jv with stm32l5 octo spi insted of quad spi.. is there anybody help me. ı could not write correctly.. and ı could not erase. correctly. first problem is when ı was write whiel start addres 0 my code write start to t...
Working with the STM32H747i-Eval board with a touchGFX application. Need the QSPI for assets and not wanting to use the BSP due to wanting to have more control over clock speeds and pinout configuration.I'm in need of some more experienced advice whe...
Hi there!I am using STM32F413ZH based custom board, Also having Wi-Fi Module along with 32MB×2 QSPI. Wi-Fi module is connected with MCU over UART3 in interrupt mode. I am looking into transfer a 1MB file from a server to QSPI. Especially I will be ge...
