I have a need to program the flash chips on one of my company's products using the PE Micro USB debugger. The solution should require a minimum of operator interaction. The product uses an MC68K processor.

I have successfully used the cprog32z utility to perform this programming task on one generation of the product.

But I need to automatically cater for several generations of the product, each of which uses a different type of flash chip.

All of the chips are, however, compatible with the JEDEC ID request command, as seen in Appendix A3 of this document:

CFI Standard

So, I need to code a solution which will read and report the JEDEC ID, so I can then decide which .32p file to use in programming the flash.

Does PE Micro provide a solution for reading this JEDEC ID?

Thanks very much,

does the USB-ML-12 rev.B support ColdFire MCU V1? And if then which SW tool do I need for debugging and programming?

I am struggling my prototype board debugging.

I am using ICDCFZ ColdFire BDM Debugger + USB ColdFire Multilink Rev.C through the 26-pin connector talk to MCF54451.

This debugger system was verified for a MCF5445xEVB. It works.

But for my prototype board, ICDCFZ can not "communicate with the target".

My 26-pin BDM connector circuit was designed refer to the MCF5445x Reference manual:

Pin-1 : unconnected (also tried connecting it to CPU_RSTOUT)
Pin-2 : TMS/BKPT
Pin-4: DSCLK
pin-6: unconnected (also tried connecting to pin-24 for PSTCLK)
pin-8: DSI
pin-10: DSO
pin-7: BDM_/RSTIN (connected the logic circuit to generate MCU reset signal)
Pin-3,5,11,23: GND
Pin-9: 3.3V
Pin-25: 3.3V (also tried 1.5V)
Pin-19,18,17,16,15,14,13,12: PSTDDATA0 to PSTDDATA7
Pin-24: PSTCLK
Pin-26: /TA (tried disconnect)
Pin-21, 22: unconnected

Current status:
The system power up reset time is about 200 ms. After reset, the system power current is about 100mA at 12V.
The PSTCLK clock about 88MHz shows up (it's half of the expected system clock frequency).
Then I started to run ICDCFZ. It took a few seconds, then showed "can't communicate with the target, check the cable connection ...".
At the same time, I realized the system power current raised upto about 127mA.

Use scope, I saw DSCLK and DSI togging when I started the ICDCFZ reset, but no DSO signal was observed.

Since the debugger system can communicate with the MCF54455 evaluation board, I think there should be somewhere wrong on my prototype.
Above I mentioned some pins were "tried" wiring to different way based on previous experience and the evaluation board schematic.
But they all did not work.

I have to solve this shortly. Please suggest the right signal connections, and any comments or clues for my problem will be apprecieated!
