Porting SW from 28335 to 28377D

luca mattonai

Hi,

I'm porting an application the uses two SCIs and one timer in SW prioritized interrupt mode. The application works well in the 28335 but on the 28377D (CPU1) seems that one uart interfere with the other and they doesn't work together. If necessary I can attach relevant code.

Best Regards

Hi Luca,

I'm not sure I understand the problem well enough to offer a suggestion. It probably would help to see the code if you don't mind sharing it.

Thanks,
Whitney

Thanks, Whitney
I solve the problejanus_cpu01.zipm, I made a mistake in the interrupt procedure writing the wrong Group register. I have added the project files for your verification.

Glad to hear you figured it out! I glanced over your code and didn't spot any issues with the way you're doing the interrupt prioritization. Looks good.
