Hi,
I am coding a driver for our device under Linux,
When i finished download a firmware(suffix is .fw),The device will not be able to communication,
I think this may be the firmware problem, My firmware is coming from the hex conversion.
Can anyone help?
What did i wrong?
Thanks!!!

I am using the CY7C64013 USB controller and have a question.
I have set Endpoint2 to be Interrupt OUT and Endpoint4 to be Interrupt IN. I am using visual basic to generate a writefile API call to trigger the Endpoint2 Interrupt. This works fine. However, while in the Endpoint2 interrupt service routine, I need to send data back to the host using Endpoint4.
Question: While in the Endpoint2 interrupt service routine, is the CY7C64013 capable of seeing another interrupt on Endpoint4? I am not able to do this. I believe the CY7C64013 interrupt system is disabled as soon as an interrupt is generated, although I do not know if this is true.
I have re-enabled interrupts a soon as I enter the Endpoint2 service routine, but my code is not able to see the Endpoint4 interrupt.
Is there any test code that would show me how to do this?
Thanks,

I use the cy7c68013 with slave fifo and auto in-out mode.
And now 4 bulk pipe is used with endpoint address 2,4,6,8
but I want to chage last endpoint 8 to 10, so edit and compile and download iic file of dscr.a51(8051 firmWare). But and then can't communicate.
Sure i change the driver and do the other needed things.
Is there something wrong?
And there is some singular note in ch 8.1 of technical reference manual. "Direct connection is available only on endpoints 2,4,6,8"
What's this?, what's meaning? Show Less

Hi,
There is a function of "Supports mode page 5 for BIOS boot support" on CY7C68300C.
I don't really know what is it?
It means that can boot cd(I connect it to dvd drive)on BIOS?
Because I have a issue on another USB bridge chip:
USB bridge chipuse on a ATA DVD Drive.There ia s bootable CD on Drive.
When I cold start PC,display show "press any key boot from cd"-->it is normal.
But There will be no message "press any key boot from cd" when I restart from windows(warm start).
If "Supports mode page 5 for BIOS boot support" function of CY7C68300C can avoid
this issue?
Thank you

We ordered the Full-Speed and Low-Speed USB 2.0 Compliance Test Boards from the USB-IF ( http://www.usb.org/developers/estoreinfo/) but they came with no documentation.
These boards are manufactured by Cypress and have part numbers PDC-9058 (Full-Speed) and PDC-9051 (Low-Speed). Searching for these part numbers on the Cypress site gives no matches.
The boards use Cypress chips CY7C64613 (EZ-USB, Full-Speed) and CY7C63743 (Low-Speed).
Is there any documentation for these boards beyond what is in the Compliance Test Device Functional Spec ( PDF link)?
The boards have a bunch of switches and LEDs and I'd like to know what they do.
Thanks.

We have a test set using primer.exe to prime CY7C683000 devices.
The host PC crashed and was re-installed with XP (including a reformat).
Primer.exe runs, but no longer detects new devices.
I have tried installing the drivers that came on the AT2LP CD, but it makes no difference. There is no installer as such on this CD.
If I plug the unit in without primer.exe, it comes up with Found New Hardware AT2LP RC42, but won't recognise any of the available .inf files.
If I then plug the unit into a machine with a working installation, the device primes OK. I need to get the test machine working again.
Anyone got any ideas?
Thanks
Malcolm
