Dear,..Hi,
I try to intall a newest u-Boot on a Freescale mpc8641hpcn board.
I have does folloing:
git clone git://git.denx.de/u-boot.git /mnt/sata/usr/src/u-boot/
date -s "??/??/2012 11:20:00"
make mrproper
make MPC8641HPCN_config
make
Flash now u-boot.bin into board (per jtag interface 0xfff00000--0xffffffff)
Booting on u-boot give following output:

I have seen with debugger, the reading environment variablen from u-boot will
oberwrite neighbor data structure during writing.
The logical location of data-strutures with there Addresses:
logical Addresses per Compiler: u-boot.map
eff5ebf0 D _GLOBAL_OFFSET_TABLE_
eff60000 = ? <--- one process write here Environment Variable with big
size(0xeff60000--0x0xeff60600)
eff6031c D step_string_tbl
eff6033c D ddr2_speed_bins
eff60348 D cpu_type_list
eff6039c D cpu_type_unknown
eff603b8 d phy_interface_strings
eff603e8 d failed
eff603ec D init_sequence 0x3ffda3ec
Now I does a new Boot of u-boot (power off, .. on).
u-boot starts and stop the prozess because a problem and hang.
u-Boot read init_sequence with wrong data(pointer) in and stops
at logical address 0xfff00400 (no address translation MMU from FFFF into FFFF
at moment)
On the Stack locate process addr_trans_enabled (0xeff02060).
I am new at u-boot.
What ideas they have for me?
(older u-boot bilds (2011 or...)allso will not run).
The biggest problem is the writing on data with pointer 0xeff60000 into bussy
structures.
Best regards
Mr. Thiesen
