[U-Boot-Users] Re: Why exceptions are enabled before exception vector code is copied

Can I ask you why exceptions are enabled before exception vector code is copied to the low RAM pages ? (I am talking about U-Boot/PPC)

No exceptions are supposed to happen until then.

On my board, U-Boot crashes before relocation (when debugging) since Xilinx Microprocessor Debugger (XMD) makes a spurious "Machine Check Exception". For other reasons, such an exception could arrived before u-boot starts.

Well, then fix this problem. What do you suggest hoiw such a situation should be handled while running from flash?

Finally, it is a bug or a very strange coding behaviour...

It does not happen on other systems.
