Using tirtos_tivac_2_00_01_23 installed in CCS 6.0.0.00190 to run examples on a EK-TM4C123GXL launchpad, found that:
1) The "UART Echo" and "GPIO interrupt" TI target examples run when downloaded using the CCS debugger. They also successfully run if the CCS debugger is not connected.
2) The "UART Echo" and "GPIO interrupt" GNU target examples run when downloaded using the CCS debugger. However, they fail to run if the CCS debugger is not connected. i.e. the sequence:
- Download the examples from the CCS debugger and they function correctly.
- Terminate the CCS debug session, and they continue to function.
- Press the reset button on the EK-TM4C123GXL launchpad and the programs fail to start with no sign of life. There is no output on the serial connection from the "UART Echo" example and neither example lights the led on the launchpad.
Is this the expected behaviour for the GNU target TI-RTOS examples?
