iam writing a simple bootloader on a stm32f103ve microcontroller from address 0x8008000 and a userapp code from address 0x8008000
my bootloader code include uart1 configuratin for show some massages and spi2 configuration for communication to a spiflash and my userapp code include...
yes my system is support spi and spi flash
the problem is as i say i dont know how to write a file (bin file) to spi flash without file system and i dont know how to update firmware from spi flash. i can write an array to spi flash but i dont know how to write a file in to that.
hi KlausST
thanks for repling
i have a smd spiflash on my stm32f103 borad. right now i can read and write into spi flash.first i wanna write a bin file (output of a blinky project) into spi flash as a frimware. and second i wanna update micro prgoram whit that bin file.
with attention to we...
i know i can searh. but when i search every one explane how to do that with uart. i didnt find a step by step explnation about how to do that with spi flash. if you now a refrence please introduce to me
