hi,

i was trying to combine two example applications from the ccs1.21 for
the c54x. The first example uses RTDX to receive an array of integers
from the host. The second one uses the codec to transmit data between
the audio input and output. Both of the projects do not use any cdb-
files. My goal is to create one project through the combination of
the two example projects in order to process the received host data
and send it directly to the audio output. However, my program did not
work, because i could not combine the two original cmd-files to
create one cmd-file for my project. The two cmd-file are:

RTDX example

-c
-stack 0x0256
-heap 0x0256

/* This symbol defines the interrupt mask to be applied to IMR inside
RTDX Critical Code sections.

This example masks the timer interrupt.
*/
_RTDX_interrupt_mask = ~0x0008; /* interrupts masked by RTDX */
