EZ430-RF256x

Other Parts Discussed in Thread: CC2560

 

Hello,

We just got 2 EZ430-RF2560 eval boards and none of the 2 systems work.

We followed the procedure outlined in the wiki pages:

EZ430-RF2560 & CC256x Bluetooth Versions and Service Packs

and none of the2 board was getting the blue LED to turn on. No connection was stablished even afet pressing the switch 1, 2, and the reset on the board.

We taught the boards should work out the box.

Any ideas...

    David,

    Does the Red LED start up blinking rapidly and then stay solid? If so, the SP loads successfully.

    If none of the LEDs turn on, then it's possible that there's no software running on the board. You should then attempt to download the software using FETPro430 (for downloading the binary) or IAR Workbench (for downloading the compiled and linked source code).

    Have you tried both SPs just in case? Do you have an EZ430-RF2560 or an EZ430-RF256x?

    Regards,
    Gustavo

    Yes the RED Led turns on and blinks for a few seconds and then stays solid.

    If none of the LEDs turn on, then it's possible that there's no software running on the board. You should then attempt to download the software using FETPro430 (for downloading the binary) or IAR Workbench (for downloading the compiled and linked source code).

    Our boards are EZ430-RF256x version 2.0. On the back there's a white sticker with 2 serial # lines.

    I have burned the SP firmware on the board. I have followed the directives to nclude libTI_init_script_BT_CC256x.r43 and  Exclude libTI_init_script_BT_CC2560.r43  

    using our IAR IDE.

    Any other ideas....

    David,

    From everything you're telling me, the SP is downloaded just fine and the device can communicate. Have you modified the code in any way?

    Here are a few other suggestions:

    1) Does pressing on S1 make the LED turn on?

    2) How are you powering the board? Using the programmer?

    3) Can you use a Bluetooth enabled device to search for the EZ430 to see if it's just the LED and it shows up? Should show up in a search as BlueMSP430-....
    If the LED itself is damaged for whatever, reason, you could measure the voltage across it. If the voltage changes, then the MSP430 is triggering it to blink but the LED isn't. If the voltage does't change appreciably (at least a volt) then there's something in the software.
