Re: more advice please

I can't comment on your questions, and I have no decent experience with ARM, but:

Why do you think you need JTAG equipment. As you are on Linux/GNU the usual way is to preprogram a flash chip with a bootloader (such as UBOOT) and start the system. Now you can use UBOOT to load a Linux distribution e.g. via a serial interface.

Of course you need a UBOOT that fits your hardware, but if the hardware UBOOT is supposed to use is not too non-standard you should be able to create same without debugging.

AFAIK, a JTAG debugger will not help much when doing Linux application (user land) software here most developers seem to use code instrumentation and remote GDB via Ethernet (optionally controlled by Eclipse on the PC site).

For Kernel development (and extended driver work) using a JTAG debugger is said to be helpful in some cases.
