TMS320F28377S: SCI boot & SCIA communication GPIO84 schematic design

Part Number: TMS320F28377S

Hi Team,

GPIO84 is used as SCI boot, and should pull up to High because of SCI boot mode, Does the below design can achieve SCI boot?

After SCI boot, we need to config GPIO84&GPIO85 for SCIA function, Does the below design can achieve SCIA communictation?

Best Regards,

Zane

    Hi Zane,

    Below is from F28377S datasheet, please make sure TRST as zero as shown. 

    Secondly,  I would recommend a weak pull-up(10k ohms) on GPIO84 . Since you are using it for SCI-A later. 

    Otherthan this everything looks ok. Yes, you can get SCI-A communication as of default shown below.
