QSPI in STM32 || Write and Read || N25Q 

Of course we want to see how do it for the STM35 ! Always a pleasure to watch your video !

You are the KING!

Very, very helpful. You are a true lifesaver.

just the video I was looking for !

Thanks a lot for those Qspi tuto so clear I have developed my own stm32h75vbt6 mini pcb board and follow your tuto for flah spi and Qspi all is working as expected 😊😊😊 I have a question about erase function. Do you erase by convention before write or because it is not recomanded to overwrite data on the same adress. 2 _ how to well manage adress function when you want to acces small data to many adresses.

Awesome video, just when I needed it! Is there a chance that you will make tutorial about recording and playing sound from these two microphones on STM32F750dk? Or at least some directions where should I look for help, because documentation almost doesn't even mention microphone nor provides example of usage Thank you in advance, best luck!

​ @Controllers Tech Is there a way to look at external flash chips in the CubeProgrammer if they are not listed in the external loader list? Still looking at the W25Q128J Winbond chip.

Will there be a tutorial how to store firmware or some firmware function in qspi?

Thank you for your hard work explaining this stuff! I did this for STM32H750VB and W25Q64, but stumbled across the problem with memcpy - it throws me into MemManage_Handler. Regular read and write commands work fine, i have set up MPU parameters accordingly. Can you please tell, what could be wrong? I use a single/dual line QSPI setting, can this work with memory mapped mode? By the way, for some flash like W25Q64, chip erase delay can be much higher than default HAL_QSPI delay of 5s, so i had to ta add extra 20s delay, so loooong

Nice video, thanks :)

Hello great video, just a question can this tutorial work on STM32H750 Discovery bd? is it the same QSPI flash ?

Hello Controllers Tech! Do you know any method to emulate the external NOR flash memory? Ofcourse they have very high erase/program cycles but still how to manage writing to flash memory by avoiding writing to the same address?

When I build project with release mode on STM32CubeIDE it stop working, same code works if build with debug configuration...Any Suggestion/ Help ??

in respond to your reply : could you please do a video on STM32H745 Discovery QSPI flash MT25QL512A ?

Hi, thanks for the tutorial, you said that what you did is not the effective way for storing numbers, is there another way to store numbers or other data types without converting them to strings ? will the memcpy() do the job ?

Great tuto as usual! Is flash memeory limited regarding writing operations number?

i am not able to read more than 256 bytes in externnal spi I am reading 4 bytes of structure after 256 bytes data is rollover

Hello @ControllersTech thanks for the video. you said in the beginning that you will tell what changes will be required for MX25 chip. Can you please make a video or explain it

Hi, very interesting video!!! I'm using H743ZI2 with dual IS25LP032. Do you think the MT25TL example can be adapted to my case? If so, may you suggest me which modifications I've to do, please?

good thanks, i can run now the n25q with your libreries. With these modification can be delete the warnings uint16_t number = 1234; uint8_t buf[5]; sprintf ((char *)buf, "%u", number); if (CSP_QSPI_Write(buf, 0, strlen ((char *)buf)) != HAL_OK) { Error_Handler(); }

Thanks for your videos, they are really helpfull, I am using your driver in the 32F746GDISCOVERY , it has the same flash memory N25Q128A. The code is stopped when the I try to execute the CSP_QSPI_Erase_Chip() function. When I debug the program, I saw that the program is stopped when I execute the HAL_QSPI_AutoPolling() function if I press "stepover" to continue to debug, but if I press "stepinto" everything is OK. CSP_QSPI_Erase_Chip(){ ... QSPI_AutoPollingMemReady(){ ... HAL_QSPI_AutoPolling() ... } ... } The program run without any problem if i don't use the function CSP_QSPI_Erase_Chip() function. Is there any update for that function? Could you help me with that?

How did you choose the fifo threshold?

Great movies i like your works a lot. So i have board STM32F508-DK F7508-B05 and normally memory chip is N25Q128 and unfortunately i have a problem, i do not pass the step QSPI_AutoPollingMemReady in the function CSP_QUADSPI_Init and i do not why.

Can this solution be easily modified to support Winbond chips? I've tried the solution as is with a W25Q128J but fail on the QSPI_WriteEnable() in the CSP_QUADSPI_Init(). Any suggestions? Update: reducing my clock speed from 108MHz passed the CSP_QUADSPI_Init() but it still times out in the CSP_QSPI_Erase_Chip() during the QSPI_AutoPollingMemReady() call.

Hi, thank you for video and code. Is this code compatible with QSPI w25q64 chip?

Please make tutorial about stm32+ros(robotic os).

Hello Controllers Tech, Thanks a lot for the video, it was very helpfull! I am facing an issue with the "Write Enable". When I call the Autopolling Function for changing the mode, the status match flag is not set and I know why. Unfortunately, I don't have an oscilloscope to check the HW part. Do you have an idea about what could be the issue? Thanks a lot and keep going :) Issue Resolved: Thank you, I have resolved the issue by using the 2 banks (MT25QL512) in the STM32H750-DK Board. But I still have an issue with the read. When I read from memory and check in the DR register, I don't find the correct information, always I get 0x88888888 and erase state of the memory 0xFF.
