Zahada FreeRTOS

[Jaroslav Buchta]

Pri vytvareni tasku se vytvori be TCB strukture reenrantni systemova 
struktura takto:

     #if ( configUSE_NEWLIB_REENTRANT == 1 )
         /* Allocate a Newlib reent structure that is specific to this task.
         Note Newlib support has been included by popular demand, but is not
         used by the FreeRTOS maintainers themselves.  FreeRTOS is not
         responsible for resulting newlib operation.  User must be 
familiar with
         newlib and must provide system-wide implementations of the 
necessary
         stubs. Be warned that (at the time of writing) the current 
newlib design
         implements a system-wide malloc() that must be provided with 
locks. */
         struct     _reent xNewLib_reent;
     #endif

Cili jako vlozena do struktury tskTCB.

Pri volani vTaskDelete(NULL) se vola na tuto polozku:

         #if ( configUSE_NEWLIB_REENTRANT == 1 )
         {
             _reclaim_reent( &( pxTCB->xNewLib_reent ) );
         }
         #endif /* configUSE_NEWLIB_REENTRANT */

coz vede k pouziti funkce free a to zase k destrukci struktury heap...

V cem je chyba? V pouziti knihoven EmBitz, nebo ve zdrojaku FreeRTOS? 
(Je to vygenerovano CubeMX)
kdyz radek _reclaim_reent( &( pxTCB->xNewLib_reent ) ); zakomentuju, 
vsechny alokace pameti funguji OK.

Dalsi problem je s SD kartou (pres 1b SDIO) cteni celkem funguje, pri 
zapisu je potreba vkladat 2ms pauzy mezi zapisy, zatim jsem to 
podrobneji neanalyzoval ale je to divne. (zase vse - SDIO, FatFS, 
nastaveno z CubeMX)
