There is a fast and dirty jtagfs now, with two files so that people can play with it. This is the kind of things it can do, though there are no breakpoints yet:
usb/serial echo b115200 s15 l8 pn > /dev/eiaU5.1/eiaUctl window -m con /dev/eiaU5.1/eiaU kill 8.tagfs|rc /usr/paurea/src/jtag/jtag/8.jtagfs /dev/jtag*/jtag echo reset > /n/jtagfs/ctl #start the jtag echo cpuid > /n/jtagfs/ctl #see debug.h for the string echo debugstr kc> /n/jtagfs/ctl #go into debug mode echo enterdebug > /n/jtagfs/ctl cat /n/jtagfs/ctl #you need to be in mem debug mode to see something here... echo dump 0xc02dc244 0xc02dc2a4 > /n/jtagfs/ctl echo exitdebug > /n/jtagfs/ctl echo debustr ew > /n/jtagfs/ctl /n/jtagfs/mem can be used to read raw memory at an arbitrary offset #set entry on exceptions echo veccatch RSDI > /n/jtagfs/ctl #wait for entry in debug state (with timeout) echo waitentry > /n/jtagfs/ctl
