First of all, thank you very much for the wonderful tech support and assistance! I have recently purchased a F28P55X LaunchPad as an alternative to my F28069 and to use as HIL setup based on the recent post I made earlier.
I have already run a sample code of a PWM + phase shift in the F28P55X using CCS to ensure that it is working. However, the same cannot be said to PLECS where this error shows up:
Attached here is the sample model I made to initiate a PWM + phase shift for review.

Some information that may be useful:
-
TI C28 version is ti-cgt-c2000_22.6.1.LTS (I have downgraded from 22.6.3)
-
Uniflash version is uniflash_9.3.0
-
Version of my computer is macOS 26.2
-
PLECS version is 5.0.2
-
XDS110 firmware is 3.0.0.41 (updated already using xdsdfu)
-
F28P55X LaunchPad Serial Number is CL55250800741 (updated already using xdsdfu)
Thank you so much in advance!
Hello!
I would verify the following things:
- Ensure that if you wish to specify the serial number, that it is correct. Note that if Specify Serial Number is not checked, PLECS will automatically detect any P55 that is connected to your computer and program to it. My serial number is CL550001, I noticed the one you entered is significantly longer. You can see the Serial Number by opening the Uniflash GUI application.
- Ensure that you are abiding by the DIP switch settings specified in our user manual (https://www.plexim.com/sites/default/files/c2000manual-2-2-3.pdf). For example, S2 should have both switches set to the “0” position to correctly route the GPIOs needed for serial communication.
- Verify your USB cable is a data cable (and not a power only cable).
I tested on my side and your software versions should work fine for programming the LaunchPad. I imagine given you got it working via CCS that number 1 is the culprit, but if this doesn’t work we can explore further!
Hello Sean! Thank you for this. Turns out I just need to not check the serial number and I got my LaunchPad working. Thank you for this!
