Not sure why you are getting a warning for something you may not have set,

but look at global resources, and bump up the Trip Voltage in the global settings.

 

Regards, Dana.

Look at the TRM page 292, it gives you the information concerning the POR. According to the TRM(Technical Reference Manual) there is 3 available voltage for the POR.

 

I don't think you can get rid of this messsage since you can't set this parameter in the global resource pane.

 

Hope it helps

Yes, I originally just noted and disregarded this, ( and it was in configuration step, not build, sri) It was  a "Level 1 warning". Just thought that power on reset might be important, but not in 'main.file'.

Will check suggestions, and thanks.

According to the DC POR and LVD Specifications from a 28xxx datasheet,

 

 

I cant seem to find any options to change POR from the GUI, so I guess this warning is to let you know about the current POR setting. The 2.9 V corresponds to the default value for the POR bits in VLT_CR register, which is 00b

 

If you want to set any other POR level, you have to modify the VLT_CR value in your code.
