FreeRTOS Add-In 10.4. and MCAPI leads to Data Fault Exception

Hi Phil,

Apologies for the delay in replying.

MCAPI should still work for the 10.4.x version, little has changed between 10.0.x and 10.4.x that would cause compatability problems.

Without being able to run the project we couldn't tell you exactly what's gone wrong, can you send it in to processor.tools.support@analog.com for us to look at?

The bad address being 0x000000018 implies that it's a struct offset from a null pointer, which potentially means an allocation has failed. Do you have the malloc failure hook enabled (configUSE_MALLOC_FAILED_HOOK) ?
Another possibility is stack corruption if your stack size for a task is too low.

If you look at the error PC (0x8940ebd6) from the disassembly window it should hopefully be able to narrow down the function and code which has gone wrong.

Regards,
Murray

Hey Murray,

Thanks for the reply.

I have solved the problem and it had nothing to do with the MCAPI, it works perfectly.
The problem was that I made print statements via the Sharc core, which slowed down the MCAPI communication. I changed this to UART I/O.
And secondly, I didn't consider that I can no longer use multiple semaphores for tasks that depend on the MCAPI.

Now everything works as it should :)
