    stmhal: Initialise stack pointer correctly. · eaaebf32
    Damien George authored
    Stack is full descending and must be 8-byte aligned.  It must start off
    pointing to just above the last byte of RAM.
    Previously, stack started pointed to last byte of RAM (eg 0x2001ffff)
    and so was not 8-byte aligned.  This caused a bug in combination with
    This patch also updates some debug printing code.
    Addresses issue #872 (among many other undiscovered issues).
