UART cc2538 Z-stack

Try to refer to e2e.ti.com/.../395042

Thanks you YiKai Chen,

The uart problem solved. I have a new problem

When i debug use J-Link, i debug with Step Over. When to function osal_int_enable(INTS_ALL), then occur interrupt IntDefaultHandler in file startup_ewarm.c

I open View->Call Stack then:

Or sometimes I send data to cc2538 by UART also call to this interrupt, which is not interrupt from uartConfig.callBackFunc.

Please help me solve this problem

If you try original SampleLight example, does it stuck there? I test with my CC2538DK and it works fine.

With SampleLight example, it works fine. But with My application, only different is i use 2 UART and 1 function callback.

I'd love to know why it jumped into startup_ewarm.c file because i don't call it anywhere in my application.

Thanks you YiKai Chen

If you disable UART, do you still see the problem?

Not, it not happen

I suggest you to two UARTs one by one to verify which one causes this.

Hi YiKai chen,

After i debug UART1, it stop in UARTDisable(ui32Base);

line:  while(HWREG(ui32Base + UART_O_FR) & UART_FR_BUSY)

I encountered a similar situation: 

But no resolution, I use Jlink too. Whether you have any solution to this problem ?

Do you have to call HalUARTClose? If you don't use it, can it work?
