C2000-CGT: The naming rule

Luke Chen

Part Number: C2000-CGT

Hi champs,

In C2000-CGT-19 we can find the latest version is 20.2.6, release date is 21 Jan 2022. This release date is later than the latest version of C2000-CGT-21(05 Jun 2021).

I would like to understand C2000-CGT naming rule, where can I find this information please?

Regards,

Luke

Luke,

Naming Convention is explained in this page:

Santosh,

If my customer would like to use latest version of compiler, should they determine by release date or CGT version? If we say below two compilers, which one should my customer use please?

21.6.0.LTS (05 Jun 2021)
20.2.6.LTS (21 Jan 2022)

Regards,

Luke

Luke,

Latest version of the compiler is 21.6.0.LTS.

Release date and CGT version should match. I just looked at

https://www.ti.com/tool/download/C2000-CGT-21#previous-versions

There were some bug fixed in 20.2.6.LTS. You can review the release note at:

https://software-dl.ti.com/codegen/esd/cgt_public_sw/C2000/20.2.6.LTS/README.html

It is recommended to use C2000-CGT-21_21.6.0.LTS compiler. If the customer has already late in development cycle and do not want to switch to a new compiler series, then they can pull latest from that series:

C2000-CGT-19_20.2.6.LTS.

Hope it helps.

Santosh,

I ask this because my customer is facing a strange problem, he uses compiler v16.9.1 LTS and do below simple calculations in ISR,

{

uwVBUSMovingCnt++;

uwVBUSMovingCnt &= 0x003F; //uwVBUSMovingCnt = 0~63

sdwVBUSMovingSum += (s32)((s32)iuwAdcVBUS - (s32)uwVBUSMovingRecord[uwVBUSMovingCnt]);

uwVBUSMovingRecord[uwVBUSMovingCnt] = iuwAdcVBUS;

}

All variables are defined global variable, sometimes variable sdwVBUSMovingSum gets unreasonable value and the system reports error. My customer conducts experiments and uses compiler v20.2.6 LTS for comparison, the system works well so far, no error reported.

Same code gets two different results with different compiler versions, my customer is thinking this is a compiler problem, what should I do and help my customer figure out the root cause please?

Regards,

Luke
