Hello Team TI,
I am using MSPM0L1105 for a communication module.
Kindly consider our below requirement:
Hello Rahul,
I will reply to you tomorrow because I am out of office today,
Best Regards,

Hello Janz,
We are looking forward for your response...
Meanwhile Kindly find the below update of developments at our end, for the objective we have:
For (1 & 2): We used a utility called SRecord to calculate the CRC of .hex and writing that CRC at a particular location in hex. I think it quite an awesome tool for these stuffs.
Link: https://srecord.sourceforge.net/
It would be really great if these features are included in CCS environment.
For (3): i. We use Lammert Bies website for all our CRC needs, we have verified and tested its correctness of results on multiple MCU platforms.
Link: www.lammertbies.nl/.../crc-calculation
With that regard we evaluated the Hardware CRC accelerator provided in MSPM0.
gData32 = 0x01;
gCrcSeed = 0xFFFFFFFF;
crcChecksum = DL_CRC_calculateBlock32(CRC, gCrcSeed, &gData32, 1);
We tried all sort of possible combination in CCS settings for CRC accelerator. The value calculated by MSPM0 never matches the CRC calculated at Lammert's website for any input string say gData= 0x01. FYI, the website calculates CRC_32 for following settings: Big Endian, init value = 0xFFFFFFFF.
ii. So we used open-source code from Lammert's website for CRC calculation of MSPM0 flash in run-time instead of its own CRC accelerator.
As of now using all these external patches we have achieved all our objectives (1, 2 & 3). We are further validating the results, but we still want to hear from you about these issues.
Thanks and Regards.
Hello Rahul,
I am sorry that our current tool can just do CRC verification when you download the file into MCU. We don't have related demo code about this requirement currently. Maybe we will develop related tools and demos in the future, and you can continue to use the external patches now.
