USB-to-Quad UART implementation   
Hi All,

We started implementing usb-to-quad uart in qnx 6.6.0, and i am using cp2108 chipset, when i saw silicon lab linux 
sample code there are usb related functionality, and to re-write the usb functionality & usb related structures its 
really taking time, so any one implemented cp2108 or cp21x0 device driver in qnx? or is there any reference to 
understand the concept? kindly help me out.

thanks in advance

Hi Lichun Zhu,

thanks for the reply, and can i know from where i can get the cp210x code?if you provide those details its great help.

thanks in advance

RE: USB-to-Quad UART implementation   
First you might need to move to other forum such as hardware or bsp.
Second, I am not sure how we can give this source out, you might need to talk to your regional sales folk or FAE. 
Any reason why you don't want to use our devc-serusb binary?

Re: RE: USB-to-Quad UART implementation   
Hi,

Following are my answer for your questions,

hardware or bsp: in forum i couldn't find it
you might need to talk to your regional sales folk or FAE.
<Maddy>I contacted local FAE engineer & his name is Mr. Vincent from "Advantrack", he said he will check with QNX team. 
Any reason why you don't want to use our devc-serusb binary?
C<Maddy>urrently i am using "BSP_freescale-imx6q-sabrelite_br-660_be-
660_SVN737103_JBN5" and in this BSPi am not able to find "devc-serusb", so can i know from where i can get(which BSP has
 this devc-serusb), kindly help me out.
thanks in advance.

This is a general SDP component in 6.6.0 and earlier releases:
http://www.qnx.com/developers/docs/660/topic/com.qnx.doc.neutrino.utilities/topic/d/devc-serusb.html

You can find it in the following directory on a Windows install:
C:\qnx660\target\qnx6\armle-v7\sbin\devb-serusb

Regards,

Eric

Re: RE: USB-to-Quad UART implementation   
Hi Eric,

Thank you so much, but where can find the source code?
actually i am trying to implement cp2108 usb-to-quad uart, for that i need some sample code which is already implmented 
in QNX, and i got an information saying that qnx supports cp210x, 
if i have that driver source file, i can refere that and start implementing usb-to quad uart.
so if you know where i can find the cp210x driver source, kindly provide me the details.

thanks in advance
maddy

RE: RE: USB-to-Quad UART implementation   
Have you actually tried it? Cp2108 should be supported, we support cp210x means anything from cp2100...to cp2109, but we
 are not able to test all available variant though.

Re: RE: USB-to-Quad UART implementation   
Hi,

Yes i tried it, but its not working i suspecting its problem with USB, because i just took fro linux cp210x source code 
and implemented in QNX 6.6.0 & tested its not working even i am not able to read VID&PID, that is the reason i am 
looking for cp210x source code which is implemted in QNX, if you can help in this its great.

thanks in advance
maddy
