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:
U-Boot 2012.04.01-00424-gfedab33-dirty (Jun 18 2012 - 13:16:53)

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.
