BlueNRG Project Specifics

Stack and Heap Sizes

The default stack and heap sizes are set to be 256 and 256 bytes by default when a project is created.

Target Startup Code

The startup code BlueNRG_Startup.s is common to all BlueNRG processors. There are a set of preprocessor defines that configure the startup code and are documented in the startup file itself. The startup code calls out to a weak symbol SystemInit with the stack pointer set to the top of of SRAM. The SystemInit function can be used to set the CPU clock or configure any external memories prior to the C initialisation code as such it cannot access initialised static data.

Target Reset Script

The reset script BlueNRG_Target.js is used by the debugger to reset the target board.
