Hi All,
We have interfaced 1 SDRAM to LPC3250 (Lower 16 bit data line) .This SDRAM is from Micron technolgies 32 MB(MT48LC16M16A2).
Now problem is that we are not sure whether ,can we run our application code from the SDRAM ,because access from processor will be 32 bit wide , since we didn't connected anything on upper data line we will read junk values .
After seeing the refrence schematics provided by NXP we concluded that there is mistake in our hardware we should have connected 2 SDRAM (one on upper 16 bit and othe on Lower 16 bit) .
Question :
Is there still some way to run our code , can we build our code with THUMB instruction (16 bit)and run the code.
Please give your valuable feedback.
Thanks & Regards Sumit
