MSP-EXP432P4111: Is there more information available about the "XDS110 UART transfers corrupted" bug fix in the XDS Emulation Software, release 9.2.0.00002?

Mark Quinn94

Part Number: MSP-EXP432P4111

I am using an MSP-EXP432P4111 evaluation board to receive data via the XDS110 UART connection to my PC. I noticed some strange behaviour in the data received and it appeared corrupted. That is when I discovered the latest release of the XDS Emulation software had a bug fix for the following in the release notes:

XDS110: UART transfers corrupted in some versions (DBGTRC-5418)

I'm hoping to get more details about this bug as I was previously using old drivers for testing and if this bug was present in the version used, it may be the case that I redo tests to ensure any failures detected were not as a result of the bug in the XDS driver.

What version of the XDS emulation software / driver was this bug first detected?
Has the bug fix completely solved the problem or have there been any reports of this bug since the latest release?

Any information would be greatly appreciated.

Thanks in advance ,

Hi Mark,

Please could you let me know the baud rate you are using? This will help us answer your questions.

Thanks,

Hi Ashwini,

I'm using 250kbaud on the UART connection to the PC. Since I updated the XDS driver (installed the latest CCS version), I haven't had any data corrupted. I was previously using an older version of the driver, I believe from CCS 8.3.

It would be helpful to know what driver version of XDS110 the bug was present in and if the latest version has had any reports of corrupted transfers.

Thanks,

Mark

Hi Mark,

The failure was first found in Emupack 8.3.0.00003 which was released in 3Q 2019. The issue was fixed in Emupack 9.2.0.00002 released in 2Q 2020. We did receive reports from customers about UART issues in our 3Q 2019 and 1Q 2020 releases. However since fixing the issue in 2Q 2020 we have not heard of any issues.

Hope this helps.

Thanks,

Ashwini
