From the README file:
 

        Note:   Don't enable the "icache" and "dcache" commands
                (configuration option CFG_CMD_CACHE) unless you know
                what you (and your U-Boot users) are doing. Data
                cache cannot be enabled on systems like the 8xx or
                8260 (where accesses to the IMMR region must be
                uncached), and it cannot be disabled on all other
                systems where we (mis-) use the data cache to hold an
                initial stack and some data.

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

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
