Hi,

Thanks for the patch, this is definitely a bug and also other platforms should be checked.

Re: [NOTES] Multi Core support

Hi, How would non-time-critical inter-core communication using, say, a shared memory area fit into this scheme? At one level it's not really synchronisation/interaction - potentially just signal an event to the processor which must respond. Depends how you interpret the words. For mutual exclusion o...

Re: linking troubles with STM32F platforms

Re: RT 19.1: Exception Handling for Fast Interrupt

Hi, RT CM port default settings are already OK for what you need to do: Priorities 0 and 1 are reserved as "fast interrupts", priority 2 is reserved for the OS. The OS code cannot be invoked from fast handlers, you can use PENDSV (or some other interrupt) to delegate an action to a lower p...
