Sequence after POR

• A circuit runs on POR to ensure that the device is in a predictable state
• RCC is automatically initialized. It uses HSI to begin with, which is 16Mhz
• We then query BOOT MODE to select where we want to boot from
  • Since we’re booting from FLASH anyways, we don’t need to touch this. However, this could be different in the future
• After this is done, we have control of the execution via Start.S

What this Means

• We can write our custom start.S script and linkerscript to initialize things
• Then, we’re good to hop into main (as defined in the given linkerscript, after settings up environment for C to run)
  • This main is loaded into ____ to execute
• We can then from there setup peripherals like we would a normal bootloader (as according to the project plan)
• Then hop into the kernel (project plan for this is coming soon)
