Is there quick hint why u-boot does not start up when bdi2000 is connected to mpc5200 board.
Because you did not enter a "go" command, or used a bad address with the "go" ?
problem is simple. I load my flash programming code ( rload ) to mpc5200 internal sram with bdi2000 and program u-boot to flash. So, loading and running code
Why that? Why don't you just use the BDI2000 to load and program the image to flash?
Then when i reset system and try start u-boot it hangs in initialization code but if i remove bdi2000 it boots u-boot without problems.
What is PC pointing to after reset, and what is your correct entry point?
The bdi2000 initializtion file is based one from denx ftp server. I just ask, if this is commonly known problem before spending any bit more time for it.
I guess that reading the docs would help. See for example "doc/README.IceCube"
