BQ76PL455EVM: unable to communicate BQ76PL455EVM with TMS570LS12 launchpad

Part Number: BQ76PL455EVM
Other Parts Discussed in Thread: TMS570LS1224


I am using TMS570LS12 launchpad (it has TMS570LS1224 controller) with bq76pl455evm. I have connected EVM with 16 cells and I am unable to communicate and read any response from BQ76PL455EVM. The program is getting stuck in the while loop of the SCI module.

my connections are as below:-

EVM                          TMS570LS12

Tx                               SCI1_Rx

Rx                              SCI1_Tx

nWAKE                     GIOA0

nFAULT                     GIOA1

VIO                             +3V3

GND                           GND

I have modified my code from the example code to work for TMS570LS12. I have attached my code below.  Can anyone help me with this issue?

Thanks in Advance.
