Tool/software: Code Composer Studio

Hi,

I wanna implement a safety related feature with MSP430F5419A--a ROM test at the startup of MCU for verifying checksum created by CCS using the polynom 0x11021, can CCS do that?

Hello Bob,

We do not have a checksum integrated in the MSP430 tool chain. However, the MSP430F5419A does feature a CRC module. The CRC signature is based on the polynomial given in the CRC-CCITT-BR polynomial, f(x) = x^16 + x^12 + x^5 + 1. You can read more about it in Section 14 of the User's Guide.

Hopefully this helps.

Regards,

James
