CC2640R2F: Code hangs unexpectedly when using UART serial

Part Number: CC2640R2F

Hi,

Im working on onchip OAD code and using CCS, SDK 1_50_00_58.

My code hangs unexpectedly when using UART serial. Im using Display_printf statements. There are a lot of Display_printf statements in my code for debugging purposes. Sometimes the code hangs at particular line and when that is removed it works fine. Why is this happening?

Thanks,

radha.

    Hi Radha,

    There are a few reasons why this might be happening. There could be a timing conflict with the thread resources but it could also depend on where you are calling Display_printf. Are you trying to print anything in a callback function or interrupt? Display_printf should only be called in a task.

    Hi Jessica,

    Thanks a lot for you reply.

    I think there must have been timing conflicts with the thread resources since I'm not printing anything in a callback function or interrupt and I'm using Display_printf in task context only.

    Thanks,

    radha.
