* Demo/CORTEX_LM3S6965_GCC_QEMU: Trim trailing spaces & lines
* Demo/CORTEX_LM3S6965_GCC_QEMU: Fix Eclipse build 1/2 (examples)
It was trying to build the examples, which pulled in symbols such as
`_write` that are not implemented.
* Demo/CORTEX_LM3S6965_GCC_QEMU: Fix Eclipse build 1/2 (discard .ARM.exidx)
Somewhere along the line now there is the .ARM.exidx section in the
files, we don't use exceptions so can just discard it.
* Demo/CORTEX_LM3S6965_GCC_QEMU: Add CMake
* Debug/CORTEX_LM3S6965_GCC_QEMU: Fix Qemu startup
It was tripping on port.c
/* Check that the maximum system call priority is nonzero after
* accounting for the number of priority bits supported by the
* hardware. A priority of 0 is invalid because setting the BASEPRI
* register to 0 unmasks all interrupts, and interrupts with priority 0
* cannot be masked using BASEPRI.
* See https://www.FreeRTOS.org/RTOS-Cortex-M3-M4.html */
configASSERT( ucMaxSysCallPriority );
Inspecting the value ucMaxPriorityValue gave 0xE0, and setting it to
0xE0 complains about overflow in
FreeRTOS/Demo/CORTEX_LM3S6965_GCC_QEMU/LocalDemoFiles/IntQueueTimer.c:57
/* Shift left 5 as only the top 3 bits are implemented. */
IntPrioritySet( INT_TIMER2A, configMAX_SYSCALL_INTERRUPT_PRIORITY + ( 1 << 5 ) );
* Add qemu options to run in headless mode
