Looking good. FWIW, when I load a processor on the RT-IHU, the current goes up by 50-100ma (at a bit over 5 volts). As soon as the program is loaded and starts, the current drops again.

All,
I have worked on the board a few hours over the past few days.
I got the JTAG interface put together and set this up for testing with the PC and a XDS110. When I connected them together and powered things up I initially saw the LEDs on the PCB come on which is what I expect. Unfortunately when I started trying to communicate with using the JTAG I so the LEDs go off and immediatly I checked the 3.3V supply and found it was bouncing up to about 4 volts. Not good. So I powered down and after some thought I decided the 3.3 voltage regulator was not stable enough to support out board. It's working in a feed back mode trying to hold the 3.3V while adjusting Pulse Width Modulation of the LC circuit.
I tested the board with an external 3.3V supply and noticed the current draw had increased to about 240 mA. Concerning.
I have removed the MAX regulator and put a LDO fixed 3.3V regulator on hanging in the air. #.3V supply now seems solid.
I got everything reconnected to JTAG and started again trying to test. When I tried Test Connection I was seeing a message about missing a file which I later realized was the HalCoGen file defining the board info. I then tried the one from the PAcSat project that I had but this was not working either. So I used the setup system to create a basic interface with a 4 wire JTAG. The I select Test Connection and this time it seems to be working. Still more work needed to learn what it is telling be but the two successes at the bottom of the listing below are encouraging.
In this mode the supply current is down to 190 mA feeding into the 5V supply which feeds everything on the board. May be believable.
Now time to create a proper HalCoGen file.

-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver or utilities.
The value is '-382' (0xfffffe82). The title is 'SC_ERR_LIST_SUBPATH_DELETE'.
The explanation is: An error occurred when deleting a sub-path from the sub-path select list. The sub-path may already be off the list. Thus it cannot be deleted from that list.
