ez430 RF2500 does not restore to working factory code



So I have got the ez430 RF2500T kit which has the USB AP and 2 battery EP devices. SO to do something more than just have these things running the demo code, one needs to at least modify the code. All good until you want to restore back to factory settings. I have tried using CCS and IAR and each time it appears to run i.e. the LEDS blink but no connection between the AP and ED. So TI have provided a restore tool which basically downloads the factory code from a hex file. Details below:

 

 

A quick restore tool is available to program the original code to the eZ430-RF2500 without the need of an IDE.

 

I have tried this countless times and I get a similar result when using the IDE. LEDS blink but no connection. The AP seem to pick up in the monitor program and display the temp, but the EP just won't connect.

Very frustrating when it appears that even TI restore code won't work. So I basically have (3) eZ430-RF2500T v1.0 boards that I would like to get back to default working code and view the results with the Sensor Monitor App.

Does anyone one know how this is done? so that I can at least verify the hardware still works as it should?

  • Well after a bit of time, I finally found some tutorials on the RF2500 with just the IAR code and guess what, it compiles, downloads and just works. So I now have my AP and ED back to a working setup. Now I can experiment knowing I now have a restore option.
