That's odd... As long as the object file generated from your assembly source code is included in the project and linked with the rest there shouldn't be any difference between an assembly function and a C function...

I expect that you used a dual port memory with one port connected to the TCM interface and the other on the data master? Do they have both the same address? Did you try to switch the two ports? IIRC I had some trouble when the TCM interface was connected to the s2 port on the on-chip memory. Connecting it to s1 worked better. Something to do with how the BSP tools parse the ptf file, I guess.
