Default BDM(NT) on Motorola MC68332

hi guys
what is the support of the BDM(NT) cable for Motorola MC68332 (CPU32)?
is it possible to debug? it there a GDB-bridge?
and is the protocol (on the USB side) open and provided with documentation?

thanks

This CPU uses BDM to access the CPU resource. USB BDM NT can do basic debug like single step and inspect registers.
Most people use BDM to read/write flash which can be easily done with USB BDM NT.

yes, but is the protocol (on the USB side) documented?
if so, where can I download the documentation?

I am talking about YOUR product: you have a USB-BDM cable, right?
which applications do support it? is there documentation for this?

your USB-BDM cable should talk a protocol to transport BDM-packages

I need to know if I can buy your cable and develop something!

Oh, there is no document on USB side and I am not planning to do so. Initially I was thinking support GDB on JTAG or BDM but I stopped it quite a while ago.


My future project will be develop the BDM that support other Motorola CPU (MPCxxx).

This makes your cable not interesting for me.
Thanks for your time.

Default Restoring DCT3416 back to life

Welcome to all past/present Cable Box Testers ! I pulled one of my fave boxes out of closet, a first generation HDMI w/ 160 GB Hard Drive and found that it had gone into Hunt mode and lost its identity. And, now that a new Firmware has been introduced, it lost its NVRAM and, this is where the Testing begins. This unit uses the EJTAG64 platform and the DCT6412 dll which is identical. After attaching a 10 pin Header onto the board, even an old head like me has been unable to start Testing. All I need do is to copy a valid 3416 NVRAM back on board and, I've found this to be exceptionally difficult to accomplish, just like it was several years ago. It will not Detect the Intel Flash on board, supplying values like 0000000 or FFFFFFF. And, DEBUG ON appears but, setting the NVRAM moves forward only one block on the progress scale and runs no faster than 20 Kbs and quickly hangs due to Watchdog. This box was always difficult back in the day and, remains so today. I DO want to revive this unit and, use it to record stuff. The Watchdog shouldn't matter with a 256 Kb NVRAM. I'm stuck and a bit angry. Are there any creative ideas I can use to speed the Testing process ? Thanx and, a goodday to one and all.
