Posté : 20-11-2023 13:41 ![icone du post]()
J'ai enfin pu lancer la copie avec la sonde JTAG.
En premiere analyse, elle ne montre rien d'anormale.
Mais le port serie de debug de l'amigaOS montre tout:
Voici le log :

Fault caused by load operation
Kernel command line: serial munge debuglevel=7
Registers pointing to code:
On voit que l'on voulu acceder a l'adresse 0x000000DF et on a pas le doit en mode user.
C'est un bug facile a reproduire et pour aller plus loin il faut mettre un breakpoint avec la sone au bon endroit dans le kernel a condition d'avoir le fichier avec les symbol de debug et les sources .... On doit se trouver vers #0: in module Kickstart/kernel+0x000476FC (0x018476FC) au moment du plantage.
Sinon après avoir regardé le user manual du PPC460EX, il est fait référence à un document d'erratum concernant notamment le snooping sur le cache L2, cela n'a peut etre rien avoir avec ce problème, mais est ce que quelqu'un aurait ce document d'erratum du PPC460EX.
