Now I add UART debugging to AOA example, but when I Emulator it, I find that UART is not loaded every time, which is why

Hi,

I am assigning an expert to comment on this for you. Also, which SDK version are you using for your environment?

Hi,

The screen-shot you have attached to your message does not show any error. In your case, the message saying "Error: cannot load from non-primitive location" is not an error strictly speaking (see here for details).

OK, but,Why can't my UART send data after sending it once，I found that the program was stuck in hwip_disable when I was debugging one step HwiP。i need please help,i need please help ， I have been adding UART to AOA for 1 month. But it didn't work. i use cc26x2r1 lunch pad, SDK is simplelink_cc13x2_26x2_sdk_4_10_00_78.

To be exact, when running to hwip_disable() When the data has been sent, but it cannot be debugged in the next step.

Hi,

Have you used SysConfig to add the second UART? If not done, please do so. (If needed, here is a lab to help)

Then you have to use the new UART and properly open (UART_open) it before your call UART_write. You can consult the documentation in order to get some examples to configure the UART and to use it. I recommend to use the UART in Callback mode and to run some tests (in order to see if the UART is properly configured) outside of the rtls example.

I hope this will help,

Regards,

yeah，I've opened UART_ open，so I found out in BIOS_ Start () before calling uart_ Write is bound to get stuck，I've found that this is true for any TI-RTOS based example，But I found that with the TI-RTOS example, I output system_Printf () is enough，so i just redirect UART to system_printf，it's ok.

so, i find if call uart_write() function before system_start()，It's going to get stuck，just call uart_open();
