hello
I have a stm32f030c8t6 which I wish to save some data in its FLASH memory. I use Address Page30 which is 0x08007800 in memory map. it is in 7th Sector. I've developed my code and easily saved some data in that Address. recently I tried to add some lines to my code(note: it is just some lines, for example detect if a is key pressed) but as soon as I add these lines of code, the memory on Page30 Address corrupts!
here is the buffer I tried to save
int32_t flash_buffer_w[DATA_SIZE]={0,0,9999,0,2000,20,280,1200,7000,180,650,850,63,50,3,25,3};and here is the memory map in debug mode
and here the memory when I added only lines of code(which by the way are executed in certain conditions and in startup these conditions are not happening)
what I have noticed is that: every time that I added one line of code, I monitored the memory. it seems like every time the written code proceeds to the Address which I wish to read and thus I get false saved data(maybe because this is the code data and not my saving data).
so my question is: how could this be possible? I mean I cared about the boundaries and didn't go beyond them. but how can the code violate into FLASH MEMORY Addresses?
here is the memory map in page 33 of stm32f030c8t6 datasheet
