I am trying to use my Mac to connect to a USB device that uses the
Cypress EZ-USB FX2 chip.
Pretty much every device I come across these days is using one of these...
I have read their documentation but I don't seem to be having any
success.
I tried using the EZLoader example program as a guide to how to work
with the FX2.
I made sure to write to address 0xE600 to make the machine reset and
thus enable it to have firmware written to it. I don't get any errors
from the firmware write calls but the machine does not seem to changed
after resetting it.
Generally you go:
write a 1 to address 0xE600 to enter reset
upload your firmware to increasing addresses
write a 0 to address 0xE600 to leave reset
... then the device does its 'renumerate' thingy.
Are you doing that? If so, are you sure the firmware is good?
I read that in November of 2005 philippe wicker solved the problem of
working with this chip but I couldn't find his source code.
Does anyone have any source code that they can share that shows how to
work with this chipset?
I have (at least) 2 examples in the repository on my site but they're
using the KEXT APIs...
How about you post a snippet of your code here, and get some direct
feedback.
Thank you
No worries.
