I ended up thrashing around for the cable to connect the '913 and '914 eval boards. In the interest of saving time && ... helping .. TI improve their User Guide:
Obviously, prices may change. This is accurate as of may 2018
In reply to Mike Leister:
I have a deeper problem.
I have the 913 and 914 eval boards mounted on a piece of plywood. Cable between them. Both powered at 5v via a power supply.
I have a USB2ANY to the 913. Unfortunately, the USB2ANY is bricked. I have tried a number of things to try to reload the firmware. Tried codeLader4, but it does not see the USB, only LPT. Tried the USB2ANY explorer, but it needs proper FW in the USB2ANY. Tried pressing the button && releasing it. Tried the "Gary Pajer" in "Motor Drivers" forum (//531779??) to no avail.
The firmware loader splash screen is
It then does the below screen (but not with the text) and says "waiting.." with the "..." as progress.
It then shows
I would point out the text is COMPLETELY USELESS AND INCOMPLETE.
Line #1 does not tell me what to do with the USB cable. Line #2 does not tell me what to connect.
I have tried the FW download tools I have been able to find. They all agree the FW is wrong. The closest is one thinks the FW version is 255.255.255.255, which is clearly wrong.
I would post this to another forum, but the few posts for USB2ANY failures are in forums connected with specific products. I AM STUCK.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Sorry about the issues with USB2ANY dongle. Thanks for getting the debug log on this issue.
I think this issue is related to USB2ANY firmware version loaded on your board. I have enclosed here USB2ANY firmware version 2.7. Could you please update USB2ANY dongle to this version of the firmware and let me know if you still face "MainGUI.exe has stopped working" issue. Also, you should be able to run without USB2ANY explorer running (it holds the USB port otherwise and ALP would not be able to see it)
I see you already figured out updating USB2ANY firmware: Switch S1 is used to put the MCU firmware into bootstrap loader (BSL) mode. The BSL mode is used to load or update the USB2ANY firmware and is entered whenever the board is powered-up while Switch S1 is depressed.
In reply to Vishy Viswanathan:
I have 2.7.0, but thanks. I will compare what you sent to what I have - looks like SREC format
I figured out my first problem: YOU NEED TO BE ADMIN to do the install of ALP. Normally, I can install most things without dragging in the blessed IT guy - this is a *huge* company and all that implies.
POINT #1: IT WOULD BE NICE IF THE DOCUMENTATION SAYS YOU MUST BE ADMIN TO INSTALL!!! - Lost 2 days to that little factoid...
I finally figured out the BSL mode from the various breadcrumbs in various posts. Plus, I have been doing low-level embedded projects for decades, and am quite familiar with the problem the BSL mode solves.
POINT #2: THE DOCUMENTATION ON HOW TO USE BSL MODE SUCKS. IT NEEDS TO BE CLEARLY SPECIFIED HOW TO USE IT IN ALL USB2ANY DOCUMENTATION. Lost 5 hours to *that* little factoid...
You may also want to look at the different descriptions/pictures for what is pin 1 on the USB2ANY in SNLU135B (pg 13) and SNAU228 (pg 14) - they are OPPOSITE. Plus, if you look at the PCB itself, pin 1 of the connector is on the left (square pad). If you look *very closely* at the picture on SNAU228/pg 14/Figure 13, you will see the square pad on the left, not the right. It is also explicitly called out in SNLU135B/pg 13/
POINT #3: THE DOCUMENTATION SUCKS - IT IS INCONSISTENT. I have a forum post to that effect.
My biggest frustrations are:
1. The documentation is scattered all over the place. Finding the information requires knowing this. THE DOCUMENTATION SHOULD BE BETTER ORGANIZED.
2. The documentation is inconsistent and contradictory. One finds that out the hard way.
3. The documentation LEAVES OUT the little pearls of wisdom that are critical (eg needing to be admin to install ALP) (eg. how to use BSL mode). This ends up wasting a *lot* of time && makes TI look bad.
4. A tool (ALP) tells me, when I bang into a fatal condition, where to find the log file. THERE IS NO LOG FILE. ALWAYS CREATE A SLIME TRAIL.
5. There should be a mechanism that if you search the forums for, say, USB2ANY, it would bring up, AS THE FIRST ENTRY, the forum dedicated *exclusively* to the USB2ANY. It took reading down the USB2ANY page for me to realize there was a dedicated forum. I admit I may be slow to see the obvious...
My goal is to help TI do a better job of supporting us poor developers sitting in a lab, beating our head against the wall. We don't need extra frustrations from our vendor's tools.
