WD> Yes, you will need a JTAG debugger; I recommend the Abatron BDI2000. I've read its web-site and as far as I understood - Abatron has GNU extension for GDB debugger which allows to BDM interface from GDB, right? And normal GDB has no this capability. WD> Then you can also use GDB to attach to the BDI2000 ... It came our R&D lab already had JTAG debugger, it is WindRiver's visionICE II for MIPS (out platfrom is MIPS based). Is it possible to do what I want with this device ? Unfortunately I didn't have enough experience before using JTAG emulator, so I would like to figure out now what topic should I start to study first.
