 ## Stack usage
-In the previous documentation Segger mensioned they reserve 256 bytes of stack for Open flash loaders. In newer versions the documentation mentions 512 bytes of stack with a fallback to 256 bytes for devices with low amounts of memory (for testing, the linkerscript configures 256 bytes of stack).
