Hello, I am developing a bootloader which communicates with an external flash memory (AT45DB041E) in order to check if a file is written inside the flash. This file that my bootloader is searching for is written from another program which is on the e...

Microcontroller : STM32L476RG, External flash : AT45DB041E (4Mbit, 256 bytes of page, 2048 bytes of block),SPI2 communication protocol, using HAL.I am not able to use the LittleFS library in order to read a file that is written into the flash or any...

Hi,I am facing a strange issue with the configurations of the SPI. I have an external module which I am communicating with that with SPI2. In order to read its ID I am driving the CS pin low send the command to the device receive the data and CS pin ...

Hello,I am trying to implement a bootloader, which will take a look each time it starts to an external flash memory (AT45DB041E) to see if something is written into it. If the external flash contains new data I need to read that data an write it to m...

Hello,I am trying to implement a flash erase function, which is based on the reference manual. I am using the STM32L476RG nucleo board. From there the instructions are: To erase a page (2 Kbyte), follow the procedure below: Check that no Flash memory...

@SHs Hello, you were right I redefined some parameters in the cfg structure and I have change the logic of the functions that I have implemented for block write and read and now my program works as expected! Thank you for your time to reply in my pos...

@Saket_Om Found the solution. I have added this *((volatile uint8_t*) &(sSPIx->DR))in the SPIx_receive function and everything works fine.

@Saket_Om After the second use of the SPIx_receive it stops at the while loop and can't continue.

When I am using HAL library the SPI init function is being configured like this(I know that those configurations are correct since I have implement the project with HAL and works as expected): hspi2.Instance = SPI2; hspi2.Init.Mode = SPI_MODE_MAS...

I lower the baudrate as maximum it can get and the OVR flag is still set after the second use of the SPIx_receive function
