Any good tips & tricks I should know about how to optimize the

Hello,
using rtems_binary_semaphore_post() in interrupt context is fine. Maybe
this is related to an interrupt with a too high priority, see also:

From the document c-user.pdf 25.6.6??the funciton may be called from interrupt
context. I have used rtems_semaphore_xxx API in UART drivers, it works fine.
RTEMS_FATAL_SOURCE_EXCEPTION should print the PC,LR ...
I think you can trace the PC pointer to see what makes the FATAL.

The erc32 is a single core processor and smo is not going to work at all.
You need to be using the Leon3 in the sparc family.

I am working on a multiprocessor based project and I am planning on using
RTEMS for that. I have been trying to run the example testsuites (smp01,

Hello again,
still have some troubles with post/wait binary semaphore sequence. Could
someone suggest what is a right way when you're working with semaphore
inside interrupts.
I have sys call via spidev which is waiting for the binary semaphore.
Semaphore released inside the interrupt. In some ca
