[Fx2lib-devel] Problem with running bulkloop example from fx2lib against CY3684 eval

[bali a. <bal...@gm...>]

Hello friends:

Let me start by saying that this project is wonderful.  Using sdcc to compile
8051 code is brilliant.

I am running the fx2lib sample code against a CY3684 development platform.
I am using the usb skeleton driver code with the only change being the addition
of VID/PID of the FX2 after re-enumeration.

On the application side, I have written a simple application that opens up
/dev/skel01, and writes and then reads from it.

I have been able to compile the bulkloop sample code in fx2lib, with the only
change being that I had to change the call handle_setupdata().  The
handle_setupdata() call needs a TRUE or FALSE paramater.  What should this
parameter be?  I have currently set this to FALSE.

I have also been able to load the compiled *.ihx file using the
cycfx2prog program,
and the chip re-enumerates itself to PID 0x1004.  However my
application to write
and the read from the device fails, specifically no data is being read back.

However utilizing the compiled Cypress bulkloop.hex firmware, which I
load utilizing
the 'fxload' program the application I wrote works.

Any thoughts or ideas on this problem are welcome, any suggestions on
what to try
next are appreciated?


Thank you.
