[U-Boot-Users] Problem while Enabling Data Cache for MPC8260 based custom board

[Dipen_Patel]

Dear Mailing List,

 

We have designed MPC8260 based custom board. I enabled I-Cache and
u-boot still works. But as soon as I enabled D-Cache nothing comes up on
Hyper Terminal.

 

Can anyone suggest regarding this problem? 

 

Regards,

Dipen Patel

It is always a good idea to read the documentation *before*  posting,
especially the README. It has a special "Note" section about this. If
you ignore it you get what you ask for - trouble.

Best regards,

I see this problem here also.

If it is the same problem I noted this when looking at triggers off of the 
backplane but did not see this with the REV 1 transition module.  I will see 
if this is the same problem or maybe something new.  In either case expect an 
answer tomorrow about this.
