I'm trying to debug board bringup of FreeBSD on a Freescale embedded board, and running into problems (no UART output, no idea if it's hanging or continuing). In order to debug this, I've borrowed a CodeWarrior USBTAP JTAG debugger, but I'm running into problems with this device. The TX/RX LED is blinking red when connected to the Windows laptop I need to use (funny thing is it blinks green when plugged into my FreeBSD machine, but there's no software that I can find which can utilize the USBTAP for debugging, and nothing open source that I can find supports PowerPC). My question is: has anyone successfully used this setup with FreeBSD bringup, and if so, how did you configure both the software (using CodeWarrior 10.5)--both in terms of the CodeWarrior configuration, and whatever needed to setup a project or otherwise in order to debug this--and the hardware, and what's needed to use this with a Windows host? I've googled, and come up empty. Thanks, Justin
