Just after posting the message "Interrupt management under PPC4xx platform", I noticed the thread "405Gpr timer interrupt" describing the same problem I encountered with the Ethernet interface (I work with the 405EP eval. board). I think it is due to the incorrect interrupt management, too. For this reason, and since this is my first experience with U-Boot, I posted the message "Interrupt management under PPC4xx platform" http://sourceforge.net/mailarchive/forum.php?thread_id=1968232&forum_id=.... I got a more stable situation by intializing the EVPR register like this: #if 1 /* OpenBIOS' way */ addis r4,r0,CFG_MONITOR_BASE@h /*! set exception vector prefix */ mtevpr r4 /*! to high ROM address */ #else /* U-Boot's way */ mtevpr r4 #endif
but unfortunately I still have the problem with the Ethernet interface. Did you figure out what is wrong?
