Hello,

I was wondering if it was possible to generate code for a TMS320F28377S using the configuration for the TMS320F28379S?

My code builds successfully using UniFlash, but the External Mode fails to connect (the target does not respond).

Thanks!

Yes, the F28377S is supported so long as you don’t use any dual core features. Note that the 28377S LaunchPad has different GPIO pins for serial communication than the 28379D LaunchPad. The GPIO are configured in the **Coder options + Target + External mode** tab. The documentation highlights this, copied below.

There are many other reasons why a target would not respond. First try with a simple model from the demo library to test connection issues. If your application specific model doesn’t run, refer to [this article on debugging these issues](https://forum.plexim.com/t/cpu-overruns-and-cpu-usage-a-debugging-guide/2877).

Thank you for your reply. I was indeed using the wrong GPIO.
