Re: [Fx2lib-devel] Trouble running speed.py

Hi Dennis,

Thanks for your reply, and thanks for fx2lib!

It's not a typo. Cypress claim "the CY7C68013A is identical to the 
CY7C68014A in form, fit, and functionality". The only difference is that 
it has a lower suspend current. They market it as appropriate for 
battery-powered devices (not that mine is battery powered...the 14A 
happened to be the only FX2 chip farnell.co.uk had in stock).

Unfortunately I cannot try Cypress's CyStream.exe, they seem to have 
pulled the CY4603 reference design from their site. Thanks for the offer 
to try my firmware on your board. You can get it from here: 
http://makestuff.eu/dennis/firmware.bix.bz2. It is built from unmodified 
source with unmodified tools.

The version of libusb I got was the latest version (1.0.2) from 
http://sourceforge.net/project/showfiles.php?group_id=1674. I built it 
from source. Similarly I built the latest sdcc (2.9.0) from source 
downloaded from http://sourceforge.net/project/showfiles.php?group_id=599.

I suspect it may be an issue with the USB host controller on my Linux 
PC. It's a very old motherboard (Asus/nForce2) and has definitely seen 
better days. Initially I thought of building all your stuff on Windows, 
but I'm not sure the build of libusb will work (the latest version of 
libusb-win32 seems to be from March 2007). So rather than waste time 
with Windows I'm going to install a fresh Ubuntu build on a spare HDD on 
this PC and try everything from scratch again.

I'll keep you posted.
