RTOS/MSP432P401R: UART Callback read causes abort

John Pocreva

Part Number: MSP432P401R

Tool/software: TI-RTOS

MSP EXP432p401R Launchpad rev 1.1

TI-RTOS 2.20.0.6

I am trying to write a simple UART read Callback routine. It seems that every time I call UART_Read() it works find until I send it a CRLF from my terminal program. As soon as I hit enter on the terminal I crash and I don't get a breakpoint at the UART_read call. It just goes to the abort routine.

Can anyone help point to where to look. This is my first foray into a UART on the MSP432.

Thanks

Hi John,

Could you open ROV (Tools -> RTOS Object View (ROV)), and check the Hwi module (you'll need to halt the target to see any info) check the Module tab to see if an exception was found and if so please attach a screenshot of any info shown in the Exception tab.

Thanks,
Gerardo

Hi John,

It looks like the issue may be the address it is trying to jump to which makes me think that possibly your callback function may be the issue. Can you show me how you configured your callback function?

Thanks,
Gerardo

Hello Gerardo,

Yes, it was my callback function. Sorry it took so long to get back. I had declared it incorrectly in the UART_params declaration. I know have it working fine.

Thanks
