Motorola SDI

Started by woody6886ca May 23, 2002
Can someone explain what Motorola's serial debug interface (SDI) is ?
Is it software and a cable that allows the user to debug an embedded
application running on an eval board such as the 68HC912B32 using the
BDM --or-- is it just a cable that adapts the serial or parallel port
of PC to the BDM connector on an evb? Would the SDI, an assembler and
the evb be enough to debug an HC12 application of moderate
complexity? Thanks.



Hi.
The SDI is the interface cable to connect from your PC serial/RS232 port to
the BDM port of HC12/HCS12 evaluation boards.
"MCUez" is an old "free" software that you can use to develop/debug with
the SDI on HC12 boards, with ASM source code. HC12 derivatives flash
programming full support.

For HCS12 cores, you would have to purchase CodeWarrior MOT v1.2 for HC12.
A will let development engineers reply to the latest question but if you
can handle 32 KBytes of ASM code, this solution should be friendly enough.

As a developer of emulators for the HC12 and HCS12 I personally believe it is worth to invest in good debugging tools. Plenty of debugging tools are available for the HC12 and HCS12 from a number of third parties. I believe, in several months the investment returns itself by saving in the debug time due to the better tools.

Even selecting a BDM emulator from a third party (rather than a full featured emulator with a trace) is good, as it offers C/Assembly support for all HC12 and HCS12 derivatives and to the maximum speed (currently 25MHz bus speed with the HCS12). Third party tools are also not likely to become out-of-date with the next higher speed / higher performance derivative.
