Hello,

I work on the M5271EVB board for the moment and I try to run U-boot.

The system is lost during the jump in ram.

It seems that the problem is in the cpu/mcf52x2/start.s file at this lines :

/*

* fix got table in RAM

*/

move.l %a0, %a1

add.l #(__got_start - CFG_MONITOR_BASE),%a1

move.l %a1,%a5 /* * fix got pointer register a5 */

move.l %a0, %a2

add.l #(__got_end - CFG_MONITOR_BASE),%a2

7:

move.l (%a1),%d1

sub.l #_start,%d1

add.l %a0,%d1

move.l %d1,(%a1)+

cmp.l %a2, %a1

bne 7b

If I put these lines on comment the system run in ram until the initialisation of the flash and I have this message:

*** Unexpected exception ***

*** Please Reset Board! ***

I note that before this "Unexpected exception" the global variables are on Flash (!) so the system can't run normally.

Can you help me ?

Thanks
