Subject: [U-Boot-Users] Why exceptions are enabled before exception vector code is copied
Date: Wed, 6 Jul 2005 09:45:23 +0200 [thread overview]
Message-ID: <c8f10050706004556bcca54@mail.gmail.com> (raw)
Dear Wolfgang.
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)
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.
Finally, it is a bug or a very strange coding behaviour...
Cedric VINCENT.
