Description
Hi guys... I am probably asking an irrelevant question so sorry:
In this makefile you utilized these lines of code related to SRecord:
%.vmem: %.bin
srec_cat $^ -binary -offset 0x0000 -byte-swap 4 -o $@ -vmem
if I want to extend the memory width to 64 how can I do that here?
I tried this:
%.vmem: %.bin
srec_cat $^ -binary -offset 0x0000 -byte-swap 4 -memory-width 64 -o $@ -vmem
It gives error (unknown option)
Note: Suppose I have a vector coprocessor attached to ibex that utilizes a same bus with ibex to the memory and I want to extend this memory bandwidth to 64 bit
Should I even do that in the makefile?
So the Ibex is 32bit and the coprocessor is 32bit but just the bus will be 64 to get more data for vector each time I load or store.. This is what I want to do

Research direction
Start with examples/sw/led/Makefile and the %.vmem rule, then check the srec_cat documentation for supported binary-to-vmem options. Trace whether the requested 64-bit width belongs only to image conversion or also to the Ibex–coprocessor memory bus. Done means documenting the required scope and a validated conversion or hardware design path.
