Storming the JTAG walls
iRex has officially said NO to providing JTAG support.
That also means waiting for them to finish their "grail quest" to implement a re-flash via a media card. They feel they have that well in hand even though most teams get that working in a couple days: not several months...
I suspect part of the slow down is that they're encrypting/signing it as well to avoid the Sony Reader embarrassment of providing us with a custom code re-flash tool.
If we want real debugger support for things like the ipdf crash we are going to at some point need to hook up JTAG debuggers. Someone mentioned seeing an extra connector when they cracked open their iLiad.
If someone is game to trace that connector's connections, there are economical JTAG PC interfaces available that could exploit that connector (if it is indeed the JTAG port.)
