Be careful with this: The bus speed is very high and a simple ribbon cable
won't do it, as the edge rates result in lots of cross-talk in the data
signals. There's some special ribbon cable made for this kind of thing, with
adjacent conductors "shaped" to not be parallel. As I didn't have any when I
did this, my hardware buddy used an Exacto knife and coffee stirrers to fake
some up from regular ribbon cable. Looked silly but worked pretty well.

I don't have the ezkit, but the manual says ball j1 on
the mini-bga, and pin 30 on the mqfp. Data sheet is better
word than manual I guess in this case.

Patience, persistence, truth,

Hello all,

I am trying to connect two ADSP-21065L EZ-Lab.
I have a problem in finding the Hardware Interface
between the two processors.
It is stated in the ADSP-21065L User's Manual for
particular enviroments that the pins must be connected
between the two processors as follows:
ADDR 23-0, DATA 31-0, MS 3-0, RD, WR, ACK, SBTS, SW,
BR 2-1, RESET, CLKIN
I did't find the CLKIN pin in the User'Manual from the
Board, so i was not able to short together these pins
on the both processors.
please try to help me in this topic and thanx

best regards
