DUAL USB example code ?

I'm looking for some USB dual port example code. (I'm using the LPC4337)

I want USB0 to be HOST from EHCI driver (Flash based) .

I'm using USB1 as a HS device in ROM API (using ULPI), so  i have this part done.

Looking to now add the USB0 HS EHCI Host.

Isn't there a CMIS driver somewhere for USB0 Host ?

Wasn't there a DUAL HS Explorer board using ULPI being sold awhile back ?

Seems there should be some Demo code for that ?

Anybody done this ? I think someone has.

I assume the ROM API can't support both a HS HOST and HS DEVICE simultaneously ? 

Please point me to a USB0 Host driver example that isn't using the ROM API.  

I've used the EHCI driver in the LPC54608. Would that back port to the LPC4337 ?

Hi,

Please check below thread about LPC43xx USB0 EHCI driver example:

https://community.nxp.com/thread/472522

There is an application note AN11309 about using USB1 as high speed USB host with ULPI interface.

Please download LPC4357 USB Certification Support Pack(REV 1.0) from here.

Wish it helps.


Have a great day,
Mike
