Hi Group
Having exclusively worked with ICE emulators in the past, I have some (probably dumb) questions with regard to JTAG debuggers.
Could someone explain to me how target support is done with JTAG debuggers?
I see (cheap) products which merly consist of a cable/dongle and interestingly such products do not talk much (if at all) about supporting specific targets. On the other hand the more enhanced ones explcitly list targets supported and in most cases have an impressive price tag attached to every given target.
This raises the question if the native support available inside the debugger software (i.e. GDB) contains everything needed for these more simple devices?
So far I see that more advanced products are aparently much faster when it comes to downloading and probably also are not sluggish while single stepping etc. What other advantages do the more expensive products have?
I don't mind spending money for a good product, but I obviousely would prefer to understand why/what for :-)
TIA
Markus
