CCS/MSP430FR5994: CRC on the MSP430FR5994

Randhir Kalsi

Part Number: MSP430FR5994
Other Parts Discussed in Thread: MSP430WARE

Tool/software: Code Composer Studio

Hello team,

Hope you are doing well. When you get a chance please help with below customer question:

I'm trying to use CRC on the MSP430FR5994 so the MCU can verify its own program memory. I want to verify the calculated CRC value externally from the MCU. Is there a way to generate a human readable CRC value from the binary file in Code Composer Studio? I just need to see the number. I don't need a bootloader feature or anything like that.

Any hints, tips, or tricks would be greatly appreciated.

Hi Randhir,

An older e2e post https://e2e.ti.com/support/microcontrollers/msp430/f/166/p/744049/2780279#2780279 suggests customer can use srec_cat.exe utility to generate the CRC.

Srinivas,

Please see below customer response and let me know what you recommend.

I decided to try out the software mentioned in the forum post (SRecord). I am using it with little success. It seems to struggling with the TI_TXT hex format. Does CCS itself have any tools that would output a CRC value at compile time? I am still trying out the SRecord program

Hi Randhir,

One option is to use one of the CRC computing code examples in MSP430Ware and pass the binary file as an input. There are couple of code examples that computes the CRC: crc_ex1_buildSignature & crc32_ex1_calculateCrc16. The 2nd one has a SW CRC calculating function calculateCRC16() that he might be able to use. It is clumsy but TI does not seem to have a tool that automatically does what he is looking for.
