CCS/TMS570LS3137: CAN Bus Bootloader for TMS570LS31x MCU. Not enough files to build the project.

Part Number: TMS570LS3137

Tool/software: Code Composer Studio

1. In accordance with the "CAN Bus Bootloader for TMS570LS31x MCU" (SPNA187) I assembled the bootloader, uploaded it to the board (HDK tms570ls3137). When I got to "11 Sample Code for PC-Side Application" it was not clear where to find the files for the project. The instructions say "The library and header file for NI-CAN 8473 are included in the project". But this is not so. The files nicanmsc.lib, can_bltest.c, Nican.h are missing. Where can I find all the files for building the project?

I saw similar problems here

But the issue is not solved.

2. Can I use PCAN-USB instead of NI-CAN 8473 as a CAN adapter?
