Instructions for load new firmware, NP41S

Mainly for Sylvain. There are a few different ways to do this. I will explain the most simple one.

1. Download mspdebug, an open source tool to flash msp430 devices. Choose download archive and choose version 0.23 (the latest)

2. unzip the package into a folder.

3. download the latest firmware "np41.hex" and place it into the same folder.

4. run a command shell and navigate to the folder.

5. attach launchpad via usb cable, also connect 6 wires to the NP41S unit. I would usually remove the battery and have the NP41S powered via launchpad. Please follow photo, can also checked and pair labels for Reset (r), Test (t), V+ (+), Gnd (G), Tx (T) and Rx (R)

   

6. run the following command

mspdebug rf2500 "prog np41.hex"

   

7. when done, detach unit and use.
