Posted on February 27, 2012 at 13:10It depends whether you are debugging the kernel or whether you have a board supplied with a port. If the port is already done and you are just writing apps to go on top, then you will only need JTAG for programming the board - application debugging is usually done over Ethernet.
I think this processor is unsuitable for Linux, even uCLinux, as it is underpowered and has no Ethernet connection. If, as it seems, you are new to Linux, get yourself an eval kit that already has a port and some getting started instructions. You really, really do not want to be messing around with the kernel as a complete newbie.
Lots of people have Linux ready eval boards, pick something with an Ethernet interface and a Linux port. Personally, I wouldn't use anything less powerful than an ARM9, they are so cheap these days. You absolutely cannot run Linix without external flash and [especially] RAM, there's no way you'd get enough RAM on-chip, you need megabits not a few k.
