Hi All, We've been using a P&E USB Multilink Rev C BDM debugger with our 522xx products for a number of years. Recently we've started using a 52259 chip and I have noticed that programming and single-stepping in the debugger is not 100% reliable. We have to re-power the device, re-plug the USB when programming, and the single-stepping sometimes crashes. I have used the Freescale CFM52259 Tower kit, which comes with an onboard USB debug interface that works with the OSBDM Code Warrior driver, and it is much more reliable. Does anyone have any recommendations for 52259 USB BDM debugger that uses the 40 pin BDM interface?
