cmsis-rtos

[maxzen]

Hello all,

we would like to use cmsis-rtos to interface with freertos

For every XXX() api freertos has also the XXXFromISR() version: so we need to know if there is an intrinsic that tell us if we are inside an interrupt handler, something like __get_IPSR() for cortex processors

Thank you
Max

Thank you WiFive,

what about __BKPT()? Does esp32 have a similar instruction?

[ESP_igrr]

__asm__ ("break 0,0");

should break into debugger if OCD is enabled, and raise DebugException if not.

Thank you ESP_igrr,

now I can complete my macros:

Code: Select all

#ifdef NDEBUG
#   define CHECK_IT(a)      (void)(a)
#   define BPOINT
#else
#   define CHECK_IT(a)     assert(a)
#   define BPOINT             __asm__("break 0,0")
#endif

__asm__ ("break 0,0");

should break into debugger if OCD is enabled, and raise DebugException if not.

By the way is there any support in OpenOCD / gdb to step over break instruction once reached?
