<DIV>Dynamic loader say: Duplicate symbol BSP_output_char</DIV>

<DIV>2. Also after allocate .bss section it not zeroed and static uninitialized
symbols have undefined value.</DIV>
<DIV> In standart linker bss section zeroed in startup procedure.</DIV>
<DIV> May be need memset after allocate bss section?</DIV>
