CF Flasher - Could not initialize BDM device

jasonwisnieski — Mon, 11 Apr 2016 22:20:35 GMT

I'm trying to program a custom board with an MCF5274 on it. We've done this for years on other PCs, but for convenience, I was trying to run the procedure on my own machine. For reference, I'm running Windows 7 64-bit.

I have a USB ColdFire Multilink cable. I've installed CF Flasher 3.1 as well as the P&E USB drivers (downloaded and ran the installer that includes PROGCFZ 5.74.00.0). The short story is that the PROGCFZ program can detect the Multilink cable, and detect and initialize the processor.

However, the algorithm and configuration that I have for this board are for the CF Flasher program. There, I configure the target and select PE_USB_ML from the device list, but no matter what operation I choose, I get the same dialog: "Could not initialize BDM device."

I've done this on other machines in the building many times, and I've even installed the programs before, so I'm familiar with their operation. I can't figure out why it won't work on this one PC. Any help? Thanks!

Are any of the other machines it runs on 64 bits? Do you have 64 bit drivers (and do they exist)?

People have been having these problems for a long time. Searching this forum for "Could not initialize BDM device" gets hits all the way back to this one:

CFFlasher "Could not initialize BDM Device"

I'd suggest searching for the same quoted string on Google. It finds hits on PE Micro's site.

Hi Tom, thanks for the advice. I do have drivers installed - I can't say for certain whether they're 64-bit or not, but the multilink device shows up under both the device manager and devices & printers. And, as I say, the PROGCFZ program from P&E appears to work without trouble (it can connect to the BDM pod and read memory from my device).

I had searched around, but none of the solutions I found so far have been relevant - they've all either been for different problems, reference a non-existent faq at P&E, or suggest replacing the unit_cfz.dll included with CF Flasher with a "new" one that's dated older than the one that's currently distributed with CFFlasher 3.1.

CFFlasher itself says after install to read the readme regarding installing drivers for the multilink cable, but there's no readme file.

Tom, thanks again for the help, but for now I'm going to just go back to the other machine in order to get this one task done.

Please be note that the CFflasher can not work with Windows 7 for the reason that the CFFlasher do not have the USB BDM driver within Win 7. Customer should use this tool with Windows XP.
