BQ76PL455EVM: unable to interface BQ76PL455EVM with TMS570 launchpad

Hello Amit,

Can you please provide some more details. You modified the BQ76PL455 sample code, correct? And what did you change exactly?

sample code is for TMS570LS4X so i have created driver library using Halcogen that supports TMS570LS1224 which i have attached in previos post.

Amit,

Are you sending a comms clear command and are including the CRC in all the communications?

Hi Alexander,

As you can see in the code attached in the previous post, I am sending comms clear command after wake up. can you please check the code if I'm missing something? Thanks in advance.

Hi Alexander,

Can you please guide me further? Thanks in advance.

Can anyone help me with this issue?

Thanks in Advance,

Amit,

Without additional information from your side, it is not possible to debug your setup issue. Please provide a description of the changes you made to the code and also provide the details for the hardware configuration for your connection.

Hi Alexander,

Thanks for the reply. In halogen, I have enabled GPIO, RTI, and SCI communication and enabled sci interrupt on VIM. I have copied pl455.h and pl455.c file from Example code. After that, I have configured channel select and the number of channel registers as I have connected 16 cells to EVM, later I am sending a sample and send result command to the command register but I am not receiving any values in bFrame.

my hardware connections are as below:-

EVM                          TMS570LS12

Tx                               SCI1_Rx

Rx                              SCI1_Tx

nWAKE                     GIOA0

nFAULT                     GIOA1

VIO                             +3V3

GND                           GND
