Can't Flash MPC8343 Power PC using VisionClick

Hey Guys,
I want to flash my MPC8343 Target (Freescale 8343 PowerPC by
Embeddedplanet.com.
I´m Using Windriver VisionClick and a Pobe JTAG to write  U-Boot on my
Target.

So i connect the target and enter BKM Mode. Everytime i try to flash, the
system answers " ERROR CANNOT LOAD ALGORITHM AT ADRESS XXXXXXXXX".
So i tried some new adresses but it dosent work.

i think i cant write into ram and so it is, cause i also coukldn´t write
into ram in BKM console. Using the command " sm 0x00001000 5 "
And so on i got the same error message " ERROR CANNOT LOAD ALGORITHM AT
ADRESS XXXXXXXXX".

maybe i need to change some flags before ?

Greetings 
Lee
