21061 MP memory reference

Started by Unknown ●February 14, 2001

Hello all,
I use system with two 21061 processors and the VisualDSP++1.0 tools.
I have a problem to reference a variable from DSP1 code if it is declared
within the internal memory of DSP2. Generated code looks OK, but it does
not work in the debugger nor on my system.
Problem is similar with the VIRPT interrupt which is not correct (I guess
the write operation is not done at the corect address).
Even the example provided by AD "FFTON2PE" seems to suffer from the same
problem.
Has someone experienced that problem before?

Hello,
Can VDSP++ generate a build date within the makefile or within
some other file? Is there a compiler directive or option for this
somewhere? I didn't find anything when I looked through the manuals, but
I figured maybe someone had stumbled across this or maybe wrote one and
could give me some pointers. Basically I'd like to be able to have a file
generate a text file with information in it like current date, most recent
compile / build date of program, filename, etc, without having to hard
code all that in the first place.

thanks again :)

Tom Hanley

I haven't done this with VDSP++, but I've done it with other compilers.
The idea is to use a small source file that simply has:

const char version[] = __DATE__ " " __TIME__;

Add the line to compile this just before your link command, so it
always gets compiled fresh when you link, something like this:

foo.dxe: foo.doj ver.c
cc21k -c -21065L ver.c
linker foo.doj ver.doj
