I have created a sysbios task with typical option!

I have added the source code of SPI for the task and I am calling the function of the spi in the created task.

When I try to add break point inside the function of sysbios task I get the following warning and my code dosent work!

Kindly let me know what could I change.

I want only transmission to happen I have disabled the loop back bit only in the register

SpiaRegs.SPICCR.all=0x000F; //16-bit character, Loopback mode

from

SpiaRegs.SPICCR.all=0x001F; //16-bit character, Loopback mode

Let me know what changes has to be done to have only Tx

and the error how to solve this error

Thank you

Hi
Team let me know what changes to be done for removing loop back!

I have seen that data is getting written to SPITXBU but not into SPIDAT this is this issue!
Help out with suggestion

Thank you

Hi Deepak,

How many hardware breakpoints do you have set? The C28 only has a small number of hardware breakpoints (3, 4 or 6...I'd have to look for this specific device). A couple are used for CCS console CIO output and "run to main" functionality. Take a look in your Breakpoint view and adjust accordingly.
