[U-Boot] Freescale mpc8641hpcn board saveenv hang

[TP.Thiesen at gmx.de]

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
