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...
