I just got an Altera Max II development board and tried to
use it with OpenOCD. It does not seem to work.
Take note I do not know much about CPLD now.
cuee@ubuntu64:~/Desktop/build/openocd/max2$ cat max2.cfg
#simple device - just configure a tap
jtag newtap xcr tap -irlen 5 -ircapture 0x01 -irmask 0x1f -expected-id

mcuee@ubuntu64:~/Desktop/build/openocd/max2$
openocd -f altera-usb-blaster.cfg -f max2.cfg

With UrJtag, it seems to be better.
