Hi, I'm on the apparently simple task of porting to a STM32F412 but I'm getting a mess with the startup file, cmsis, and linker file. Searching for an answer I found :
1) It jumps to "main" at the end of the Reset_Handler. You need to change it to jump to "_start". 2) There is already zeroing of the "bss" section, but you also need to add zeroing of "corebss". Of course the linker script also has to be updated accordingly (sections/labels that match). >From this devlist on an STM32F427 but still no success. I find hard to believe >you have to get into assembler with all the support and files STM gives. I can execute the main function but the timers just do not work, the blinker goes really fast (oscilloscope) and can't see where the clocks are configured. Has anyone done this port or can guide me a bit on the steps to follow? How are the clocks configured? Thanks!
