Hi,
I am using STM32F070C in one USB application with command line interface. Settings of the device is stored in flash in last 1k bank (device is 32k): 0x0800 7c00 to 0x800 7fff. I have some issues with default setup of a new project after writing to flash. After restart (or reset), the device goes into hard fault exception during startup. I single-stepped all through __scatterload and the hard fault is generated when R0 within __scatterload routine hits address which was modified during my flash write.
Then I changed IROM size in the target dialog from 0x8000 to 0x7c00 and it passed the startup and runs OK. My question now is about the startup process: where can I find some detailed info about startup process and how can I change the sections of the flash memory to r/w and specify that to linker to avoid those sections.
