hi,
Could you tell me which configuration should I use? There are 4 
configurations for MPC8313ERDB...
 >> MPC8313ERDB_33               powerpc     mpc83xx     mpc8313erdb 
freescale      -           MPC8313ERDB:SYS_33MHZ
 >> MPC8313ERDB_66               powerpc     mpc83xx     mpc8313erdb 
freescale      -           MPC8313ERDB:SYS_66MHZ
 >> MPC8313ERDB_NAND_33          powerpc     mpc83xx     mpc8313erdb 
freescale      -           MPC8313ERDB:SYS_33MHZ,NAND_U_BOOT
 >> MPC8313ERDB_NAND_66          powerpc     mpc83xx     mpc8313erdb 
freescale      -           MPC8313ERDB:SYS_66MHZ,NAND_U_BOOT
