Hi,
I need help regarding how to operate a SRAM with BF518.
I'm using the BF518f and connected it to a SRAM 1MB = (512X16)
CY6215EV30.
I'm using the ASYNC outputs:
A1-A19 , D0-D15 , AMS0n, AREn, AWEn. I read the Hardware reference the
chapter about the EBIU and the AMC and configured the AMC registers so I
will use Bank0.
My goal is to make the external SRAM chip 'glue-less', and have the
same
functionality as the internal SRAM.
I want the application to recognize that it has more memory (exactly like it
does when I check the '*use external SDRAM*' box in the project
options.
*I'm probably still missing software support:*
1) How do get the data from the processor to the external SRAM?
2) Looking at the architecture I think I have to use the PAB (Peripheral) /
EAB (External) Access Bus or the / DEB (DMA) to bring the data to the AMC
(part of the EBIU). I did not find any examples on how to do so.
3) I tried to use the examples of the parallel FLASH from the evaluation
board (which is connected similarly) but did not succeed. Is that the right
direction?
I'm not a very experienced software engineer.. so please make it simple
and
easy :-)
Thanks,
