hi
I tried to install TinyOS2.x to a node by "make install XXX jtag"
this problem comes :
Traceback (most recent call last):
File "/opt/msp430/bin/msp430-jtag", line 16, in ?
from msp430 import memory, jtag
File "/opt/msp430/lib/python2.3/site-packages/msp430/jtag.py", line 44, in
?
raise ImportError("Can't find neither _parjtag nor ctypes. No JTAG
backend available.")
ImportError: Can't find neither _parjtag nor ctypes. No JTAG backend
available.
Anyone can help me ?
