Other Parts Discussed in Thread: CC2430

I have the SmartRF04EB + SOC_DEM connected to CC2430EM (battery board) + SOC_BB via 10 pin link.

Getting error???

Chipcon SRF04EB NO EM detected.

LED

2 = Red

3 = Yellow

4 = blue

    Hi Clive,

    Ok a few tips/things to check

    1) Can you see the EM on the battery board in SmartRF Studio for example?

    2) Are your batteries fresh/holding enough power?

    3) Have you tried orienting the cable the other way?  On the smartRF04EB the tab should be facing away from the LED and the red stripe on the bottom left.  On the BB, the the tab should be facing away from the EM and the red stripe on the bottom left.

    When I find the device in SmartRF Studio or another program I see that my LED is blank.

    I hope this helps.  It is likely just the orientation or batteries.

    Cheers,

    Yoda

    Hi Clive,

    as Yoda already explained, please make sure you have proper power on the SOC_BB (battery board). It will not be powered by the 10-pin cable (pin 9 that normally carries VDD from SmartRF04EB is not connected on the SOC_BB connector -- also, the pin 2 on the "SoC debug/flash" connector on the SOC_BB (the one that says "3.3V") is used as a loop-back _from_ the SOC_BB's VDD to the voltage level converter on the SOC_DEM, in order for it to convert signal levels properly).

    So please check your SOC_BB batteries (or its power source) and make sure the power switch is in on (left) position. After you have connected the two boards and powered the SOC_BB, try to cycle power (or press the S300 "USB MCU Reset" button -- right below the LCD) on the SmartRF04EB (for the USB MCU to retry the detection procedure).

    Hi

    Thanks for the reply.

    I was using a batteryboard (SOC_BB), using 2 batteries to power the unit. It had a small power switch, tried it in both positions.

    Would this problem occur if the software, including sample aplication, was not installed correctly?? The 2 smartboards communicated with each other perfecltly!!

    The university will not let me borrow the unit, I have to use it within office hours not over weekends. As I work full-time, this is very limiting. So I need to sort out all the problems (in my head) before going back. I cannot afford to waste anoher day.

    Thanks

    Clive

    Did you solve it?

    The problem of the SmartRF04EB not detecting the external CC2430 on the SOC_BB (battery board) should have nothing to do with what software you have on the CC2430. The CC2430 is held in reset, then interfaced via its debug interface. As a test of the CC2430EM or the EB you can verify it's working when plugged directly into the SmartRF04EB (removing the SOC_DEM). However, if you (somehow) have locked the debug interface this will not work (the chip will not get detected). If so, you can download the Flash Programmer tool from TI, and try to reflash it with any HEX file. If it is locked you should get a popup and the option of doing an entire chip erase (NB: you will lose flash contents) and unlock it.

    Did you check Yoda's tip #3 to make sure you had the correct cable orientation on the 10-pin header? The truncated corner on the silk print around the header is pin 1, and should be matched.
