RTDX in assembly for 55x - Thomas Shen - Mar 4 12:55:34 2007

Hi,

I would like to be able to use the RTDX functions (RTDX_readNB,
RTDX_write etc.) in assembly on the 5510. The TMS320C5000 DSP/BIOS API
reference guide (spru404g.pdf
http://focus.ti.com/lit/ug/spru404g/spru404g.pdf) says that there is
no Assembly Interface for the RTDX module on the 55x. I have tried
copying the assembly code generated by the compiler for the
corresponding C functions but that has not worked. Also, I have
attempted to call C functions and that has not worked, but it does
compile. Is there some register bit I need to set?

Does anyone have experience in using RTDX from assembly and know how
to get the RTDX functions working in assembly?

Thanks for any help.

Thomas
