Hello,
I have a problem viewing static ram chip off of GPMC bus.
I am using the Lauterbach emulator and setting up the nCS2 signals with nADV, nWE and nOE with a scope and they all look good.
I am using address/data multiplexing. If I disable MUXADDDATA I can read and write memory in the CS base address.
If I enable MUXADDDATA I then cannot write memory and when I view memory it is sequential numbers in memory which I cannot change.
Is there any suggestions I can try ???
My address and data lines are setup in hardware for extended addressing using data-lines as A1 thru A16 and A1 thru A8 as A17 thru A24.
And I am using the 16374 for multiplexing the data-lines to address-lines.
Please help - because I am behind in my project.
Thanks in Advance,
John
