DSP/BIOS with C6416 TEB

Started by Kevin Howson ●April 10, 2003
Hi,

We have a customer using the C6416 TEB with an emulator and CCS. He is trying to
run the first simple DSP/BIOS example and use Log_printf() to print "Hello
World". The code seems to run OK but nothing is printed to the Message Log.

Has anyone got any ideas / seen this before?

Thanks in Advance,

Kevin

Kevin,

The TEB6416 shipped with an early version of the C6416 (rev 1.03 I believe)
that did not support RTDX. DSP/BIOS uses RTDX to update the Message Log
while the target is running - so this would explain the lack of update while
running.

The message log should update the instant the target is halted via emulation
reading the log buffers, if this is not happening then there may be another
problem. If RTDX is enabled in the bios configuration file (hello.cdb)
then this may explain this behaviour. Solution here is to disable RTDX and
to set the HST link type to 'none' (in the Graphical Config tool under the
Input/Output folder - RTDX and Host Channel Manager).

Current shipping versions of the c6416 support RTDX.

Hope this helps.

Thom

hi, you must check the library wich contains that command(log_printf), maybe you must to extract some sources or headers files from another file that you need to can use that command,!

i had that problem with an example of codec for a 6201, it did not make nothing, even print a message, until i'd extract a serie of libraries and source files from a *.src file, then it'd works, try this way!!
