Re: Remote debugging ( target : ARM7/linux ) (host x86/linux ) with JTAG emulator : how to choose ???????

Both the BDI2000 and the Jeeni work well with GDB/Insight.

I'm only familiar with the ARM7TDMI, but it works fabulously!

In my experience Angel (and RDI, same thing) aren't as well supported under 
GDB as the GDB remote protocol is. The Jeeni speaks RDI, the BDI2000 speaks 
GDB. The BDI2000 also has a handy telnet terminal, for when you're having 
trouble with GDB.

I'm only familiar with elf. It seems to be the most common format for ARM 
targets. Works well.

If by "kernel" you mean Linux kernel, I have no idea as I'm not running Linux 
on my target. I am able to debug our in-house RTOS quite well though. I'd 
even be willing to say it works *better* than local mode because you can step 
through interrupt handlers much easier.
