Thank you Jerry,
This removes some magic!
Do you know by any chance what the reason can be for
Loading u-boot.bin , please wait ....
# PPC: timeout while waiting for freeze
*** TARGET: reset detected, restarting target
I have HRCW 0x0E74B20A, (ISB100), so I have changed my BDI config
; init core register
WREG MSR 0x00001002 ;MSR : ME,RI
WM32 0xF0010004 0xFFFFFFC3 ;SYPCR: disable watchdog
WM32 0xF00101A8 0x04700000 ;IMMR : internal space @ 0x04700000
'md', some other commands work fine but 'load' is 'timing out'?
u-boot as stand alone starts without problems (HRCW come from flash),
BDI is not resetting anymore apart from case when I do 'load'.
