Recommened P&E USB ColdFire Multilink firmware and driver for CW7.2

[mjosborne]

Hi there,

I upgraded the firmware in my P&E USB ColdFire Multilink (Rev. D) to version 5.54 when I was getting a new development environment up under CWMCU10 and 64-bit Windows 7.  Now when I go back to my 32-bit XP to use 7.2 I can erase and program, but not debug (see attached screen shot).  I see the following error message: Unknown protocol error.

I would like to roll back the firmware to the stock (or recommended) but don't see a way to do so.  The P&E firmware update instructions here:

under:

Firmware version 5.54 for the Coldfire V2/V3/V4 Multilink (Part# USB-ML-CF) Updated 11/24/2011

aren't very helpful.

I used 'Testcfz.ex' to update originally but it doesn't allow downgrading (see https://community.freescale.com/message/104104#104104

I updated the P&E Windows drivers to v10 but no change...

Please help as this is a real pain.

Thanks,

Matt.

Hello,

Try to update unit_cfz.dll in C:\Program Files\Freescale\CodeWarrior for ColdFire V7.2\bin\Plugins\Support\ColdFire\pemicro with a newer version.

Funny, I'm having the reverse problem - I can connect OK & debug but can't erase or program on my Win7 PC:
