C54X File I/O newbie

Started by cp_1919 July 28, 2003
I'm trying to write a dll which will load a COFF file onto board (via
JTAG), and start the code, and send data to and from the parallel
port/JTAG/board.

It would seem that everything that I want to do is available in the
evmdsk54x.dll. But I can't get it to work. I'm pretty sure that I'm
loading the COFF file correctly, but I do not that that the code
starts running, and when I try and step into evmdsk54x_fifo_write I
never return.

The problem is that there are multiple points of failure here, and I
am not sure what needs to happen to get things rolling properly.
Documentation of what is needed and how it works is pretty scarce.

I would assume that it is necessary only to do this:

evmdsk54x_open
evmdsk54x_hpi_open
evmdsk54x_reset_dsp
evmdsk54x_coff_load
evmdsk54x_hpi_write_single (start address)
evmdsk54x_unreset_dsp
evmdsk54x_fifo_write

what am I missing, or am I totally off base here?
