[U-Boot-Users] Problem with serial port

[rameah nathan]

Hi all,


    I have configured u-boot (U-boot-1.1.6) for my new board MPC8560ADS as
per the guidelines provided in the README file.I am very new to the
bootloader.I made changes only in the include/configs/MPC8560ADS.h file as
given by u-boot manual like (memory map of flash,DDR,Rapid i/0,pci) and
baurdrate.I have attached my MPC8560ADS.h file for reference.

After flashing my u-boot in to the flash,there is no output from the
minicom .I have check baurdrate and other settings.

When i try to debug u-boot using BDI-2001 it get struck in the file
serial_ssc.c file in the function
serial_putc
and Program counter strucks at this place without futher increment
afte single stepping.
 I am using SCC1 for console.

can anyone tell me what could me the problem.And how to proceed futher from
here.

Regards
Ramesh.K.V

Please first of all update to the top of tree git version of
U-Boot. Debugging old versions is considered a waste of time.

We usually recommend using kermit instead of minicom, which has caused
trouble before. Configuring it is easy:

Please update your U-Boot first of all. If your problem persists, let us
know.
