c6711 daughtercard

Started by Adam Watkins June 28, 2001
Hi all,

A colleague of mine is using one of Dsp Global's Protoplus Lite boards
to build an interface to the C6711 DSK. He doesn't appear to be getting any
signals from the two Timer pins, address or data pins. The ECLKOUT, Reset
and 5v, gnd signals seem to be ok. I saw that the C5402 has a Daughtercard
Present signal - does the C6711 need something similar - either in hardware
or software, to alert the motherboard that there is a daughtercard attached?

many thanks,
Adam



Hi Adam,

the C6711 DSK doesn't need any presence signal to tell it that a
daughtercard
is present. However, you should be aware that it is only CE2 and CE3 type of
addresses that will be passsed on to the daughtercard site. The TOUT0 and
TOUT1 signals are however always passed on. (We use those signals on some
of our own daughtercards, Ethernet boards, Codec boards, and RS232 boards)
Please note that TI changed the location of the CE2 Chipselect on C6211 and
C6711 DSK. The C6711 DSK can be made compatible with regards to this simply
by installing a specific resistor.

Let me know if you have any more questions,
