NDK 2.0 crashes evm648

Ludy --

The "LOCK NOT CALLED IN TSK CONTEXT" error you show above is usually caused by an ISR or SWI function calling one of the RTS functions that is only allowed from thread context.   BIOS registers a lock/unlock functions with the RTS library.  The RTS library has a few functions that are not reentrant and need to use this lock to protect from multiple threads corrupting some global data structures.

The most common suspect is and ISR function calling printf().  printf() internally acquires a lock.

I am not familiar with the ethernet driver for DM648, but I did a quick review of the code and it looks like there might be some printf() calls that could be made from ISR context.

If you are able to rebuild the ethernet driver, I would suggest changing the printf() calls in the driver to 'LOG_printf()' calls.  Or, you can place breakpoints on the error conditions and see if one of these is to blame.  Look for 'printf()' in the hal/evmdm648\ethss_dm648\*.c.  

The ones I suspect are in red below.  Can you place a breakpoint on those and see if you hit them?  And then see if this abort occurs soon after that?
