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:
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.
