Can anyone suggest a good JTAG-based emulator with a good Windows or Linux-based debugger? Microchip's tools were very inexpensive and pretty powerful. PowerPC's were a bit more expensive. I need something where I can build U-boot with its makefiles, that we all know and love, load the code into flash and/or ram, set breakpoints, single-step, look at variables, look at C-source code, registers, possibly an IDE/editor, etc.
As already mentioned, we too strongly recommend the BDI3000 by Abatron. It fits perfectly into a GNU toolchain based development environment, has full MMU support (which is essential when it comes to Linux kernel debugging) and supports a wide range of embedded processors - ARM, PowerPC, MIPS, ColdFire, ...
Best regards,
