Hey Guys. Im trying to do some testing with ktest but don't seem to get any desirable results. At one point, I got the "W" command to work, but it resulted in a BAD response , which I would think should be accepted, if Im reading the code right using Below Var:
Work = ["4375c3b7a27cc936f295a6140358e965319322e7cfd11e137df42ea60864a675", "218d522051d547d51a00c94e", "b2cc9f74", "accept"]
Now, I run W command (aftere restarting ktest) and I get no response at all!
Trying to find out if theres a proper method to using ktest or if there could be something wrong with the K16.
I added a small debug output in sendcmd under the dev.write line:
dev.write(0x01, cmd + chr(addr) + data, 0, 500)
print "tried %s %s %s" % (cmd,addr,data)
python ktest

Is there something I am missing here, or something else I should be checking out?
thanks
It is most likely a hardware bug in the circuit. During our testing we realized that the Dual NOR gates used in the design are too fast, and there needs to be some propagation delay. Using a cheap NOR gate chip from Fry's did the trick. We are still trying to see if this can be fixed in the firmware.
