Message: 49532    Hello,

 

We are using BF561 customised board with silicon version 0.3.

 

We have update the SDRAM from 64MB to 128MB.

 

I am aware of hardware anomly..... But exactly what is that don't know.

 

Means when we type "free" on hyper terminal it will just show Total memory around 54MB, but actually what?

 

Do we have 128MB RAM memory available?

 

After boot I have tried meminfo & cpuinfo as below

 

MEMINFO as:-

 

MemTotal:        54596 kB

MemFree:         42332 kB

Buffers:           164 kB

Cached:            440 kB

SwapCached:          0 kB

Active:            520 kB

Inactive:           84 kB

SwapTotal:           0 kB

SwapFree:            0 kB

Dirty:               0 kB

Can any body brief me about  hardware anomly & SDRAM through this????

 

Any help highly appretiated.
