Hello,

i will use CONFIG_PRE_CONSOLE_BUFFER and have some trouble.


myboard.h
     #define CONFIG_PRE_CONSOLE_BUFFER
     #define CONFIG_PRE_CON_BUF_SZ            4096
     #ifndef __ASSEMBLY__
     extern char preConsoleBuffer[] __attribute__ ((section(".data")));
     #define CONFIG_PRE_CON_BUF_ADDR            preConsoleBuffer
     #endif

myboard.c
     char preConsoleBuffer[ CONFIG_PRE_CON_BUF_SZ ] __attribute__ 
((section(".data")));


     int board_init()
     {
     .....
     console_init_f();
     .....
     }

u-boot/arch/arm/lib/board.c
     remove console_init_f(); from init_sequence list.

after this changes, u-boot will hang.

use u-boot v2013-04 on arm i.mx6 (Freescale)

Best Regards
   Johann
