Hello Dear Community,I am working on an HMI System and using STM32H7B0 with APS6404L-3SQR. I am able to do all operations including Write in Memory Mapped Mode but when I try to write 1 byte, It writes 8 bytes which is not what I expect.I have read m...
Hello,i am having problems to read data from the QSPI nor-flash if the address changes from 0x90FFFFFF to 0x91000000Everything is fine from 0x90000000 to 0x90FFFFFF but beginning from 0x91000000 there is no data.Example, i have an array stored at the...
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...
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 ...
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...
