Hi all

I tried to run u-boot-1.1.6 on my old MBX860 board (Version 20C). I tried several version but I always get the same behavoir.
No communication on the serial line. Only when I press a key on my keyboard I get a strange string back (for example RETURN give the ASCII code 170 back "¬")

What have I done:

1) build own GNU environment ( I follow for this the guideline from Dan Kegel). I did that in  cygwin under Windows XP
2) then download u-boot-1.1.6
3) make CROSS_COMPILE=powerpc-860-linux-gnu- MBX_config --> works fine
4) make CROSS_COMPILE=powerpc-860-linux-gnu- all --> works fine with a few warnings
5) I use the EPPC of the MBX to download the u-boot.bin and flash it with "pflash 4000:xxxxxxxx fc000000
6) I can check the entries of the flash with md fc000000 and their I see some text like "u-boot Version 1.1.6" --> so flash is written
7) Then I set the jumper J4 to 2-3 but then I got this strange behaviour.

I set in include/configs

#define CONFIG_MPC860                1        /* This is a MPC860 CPU                */
#define CONFIG_MBX                1        /* ...on an MBX module                */

#define        CONFIG_8xx_CONS_SMC1        1        /* Console is on SMC1                */
#undef        CONFIG_8xx_CONS_SMC2
#undef        CONFIG_8xx_CONS_NONE
#define CONFIG_BAUDRATE                9600
/* Define this to use the PCI bus */
#undef CONFIG_USE_PCI

#define        CONFIG_CLOCKS_IN_MHZ        1        /* clocks passsed to Linux in MHz */
#define CONFIG_8xx_GCLK_FREQ    (40000000UL)   /* --> my MBX has only 40MHz */

Any Idea why I do not see the startup dialogue of the u-boot bootloader ?
