MCF5407C3 (Coldfire): looking for dBUG
« on: July 24, 2023, 08:57:43 pm »
Back to 1999, the M5407C3 board was shipped with one Am29PL160C (2MByte) Flash ROM.

The first 256K of the Flash contains ROM Monitor firmware, named "dBUG", which provides the user with debug interface, inline assembler and disassembly, program download, register and memory manipulation, and I/O control functions.

The rest of the Flash was available for the user.

My board was saved today from the hydraulic press, someone must have reprogrammed the whole Flash because the VxWorks bootloader is the only thing that appears on the serial and there is nothing else in it  :-//

by chance does anyone have a copy of the have a copy of dBUG?

Why don't you ask the ColdFire community at NXP?

good idea!  I hadn't thought of that.
I don't know if they are active, Let's try  :-+

How are you going to reprogram the flash? via the BDM interface?

manually

??
If I remember correctly, the flash memory is soldered onto the board.

I have an MCF5407 evaluation board but I am in the process of moving.
If you haven't found it, you can get back to me in 3 or 4 months, I should be settled.

unsoldering the two old flash chips, programming two new chips, soldering them.

so, will you be able to copy the contents of the flash?

I should be able to dump the flash with CodeWarrior through the BDM port.
