Re: [rtl] Qs on the "sound" example

[Michael Barabanov <baraban@fsmlabs.com>]

Could you try running the threaded version of the sound example,
irqthread.c?

You shouldn't need to use breakpoint() to debug this, as any fault in an
RT-thread should be trapped in the debugger.
Note, you can only use RTLinux debugger to debug
RT-threads, and not interrupt hanlders. This is not a restriction
in practice as this example shows. Also, breakpoints and tracing
only work if hardware interrupts are not disabled.
