Part Number: LP-MSPM0G3519

Tool/software:

Hello team,

We are using MCAL : MCAL_MSPM0_00.02.05.00 package

We are encountering a compilation issue in the Cdd_Uart module with the following error:

Upon investigation, we identified that the issue is due to a missing entry for UART2 in the schema file under the CddUartInstanceName range.

To resolve this, we made the following changes to the schema:

Added UART2 to the CddUartInstanceName range.
Updated CddUartNumInstances from 7 to 8, as the expected range is from UART0 to UART7, which totals 8 instances.

Kindly review and confirm if these changes are correct or if any further modifications are needed.

Thank you

BR,

For the UART inst number and name, please refer to device datasheet, and thank you for your feedback

I will double check this tomorrow.

Hi, I can show you the actual UART that are available in G3519:

Please refer to this https://www.ti.com/lit/ds/symlink/mspm0g3519.pdf datasheet: 8.24 UART

There is no UART2. Totally 7 UARTs.

Hello Helic Chi,

Thank you for the clarification regarding the available UARTs on the G3519.

I have a small follow-up query. I noticed that the source code contains an ISR function for UART2, which initially led me to believe that UART2 might be supported but missing in the device schema. However, based on your confirmation that UART2 is not available, I believe this ISR should not be present in the source code to avoid confusion.

Ahhhh,

At least UART2_ISR will be called when UART2 interrupt is triggered.

But in startup file, there is no UART2_ISR is implement in interrupt vector.

So, even if UART2_ISR is in UART_qir.c, but it's useless.

I think we keep it in source code, is to maintain overall device's source code compliance.

Also, you can not choose UART2 in EB.

If you need to add more comments to this question or provide any suggestions, please feel free to reply to me.
