why I can't step over and have to click resume twice?

Hi,

Any breakpoints visible?

Hello Yewkui,
Without more details, it is very difficult to provide any suggestions.

Most important: What exact version of CCS are you using? Provide the full version number.

A small reproducible test case would also help a lot. Basically a project with source files and the compiled executable (*.out).

Thanks

Hi Ki

Thank you for you reply, My CCS Version: 5.2.1.00018.

I clean the project and rebuilt it again, the result nothing changed.

Other projects resume correctly, only this project need to resume twice.

I use the UART project in Self Test Kits, and change the main.c .

After initial all, I added these code, and delete all test code.


if(CORE0 == thisCoreNum)
{
CSL_semAcquireIndirect(UART_SEMAPHORE);
KeyStone_UART_config(DEFAULT_BAUD_RATE, FALSE, UART_USE_CORE_TO_TX);
sprintf(hello, " Hi,ALl! I am core %d,I boot successfully,Thk U!\n",thisCoreNum);
KeyStone_UART_write(hello, sizeof(hello), TEST_UART_NUM);
CSL_semReleaseSemaphore(UART_SEMAPHORE);
}
else if(CORE1 == thisCoreNum)
{
CSL_semAcquireIndirect(UART_SEMAPHORE);
printf("\ncore2 get smeaphore\n");
KeyStone_UART_config(DEFAULT_BAUD_RATE, FALSE, UART_USE_CORE_TO_TX);
sprintf(hello, " Hi,ALl! I am core %d,I boot successfully,Thk U!\n",thisCoreNum);
KeyStone_UART_write(hello, sizeof(hello), TEST_UART_NUM);
CSL_semReleaseSemaphore(UART_SEMAPHORE);
}

May these code cause the problem?
Is the semaphore reason?

Thank you so much.

Hi Ki

It can step over now. when I step over It run correctly

the console printf when the second time resume for core1
