A> Is there a way to simply test the Debug UART alone to see if it works? - We are working on doing a boundary scan to make sure this and other pins are connected/not shorted.
B> Can we get a write up of logical steps or validation that this should work using JTAG only?
C> Is there a document/diagram that shows all the connections and signals needed for USB OTG needed to do serial download?
D> Anything else we can check?
E> Everything always references - check with your local FAE? How do we get one?

Hi Peter
- with boundary scan one can toggle pad, for testing uart
it is necessary to run some program using jtag debugger, please
check attached sdk example. Full sdk can be provided using service request.
How to create service request :
https://community.freescale.com/docs/DOC-329745
- for validation one can use sdk it has tests for many modules
- for serial download one can check MCIMX6Q-Smart Device Board schematic
and Boot Chapter of Reference Manual
- please refer to i.MX6 System Development User’s Guide
http://cache.freescale.com/files/32bit/doc/user_guide/IMX6DQ6SDLHDG.pdf
- one can create service request or use Live Chat [in section SUPPORT]

Best regards

Igor,
Update:
- We ran boundary scan and tested our UART1 TX and RX pins - everything works / is connected / not shorted
- USB OTG will not enumerate in windows - we can't boundary scan D+/D- because they are listed as linkage in BSDL - we simplified this connection based on the schematic in MCIMX6Q Smart device board - are any of the N/C a problem?
- We will request the SDK through support and possibly initiate a Live Chat/support session.
