CC2511 deos not get detected on smartRF04EB SoC debug

Other Parts Discussed in Thread: CC2511, CC2510

Hi all,

I have developed board based on CC2511 controller. My development board gets detected with CC debugger but does not get detected on smrtRF04EB development kits SoC Debug header as mentioned in CC2511 dongle user manual rev 1.

 

Also this dongle does not get reset by pressing SoC reset on development board and gets reset by pressing USB MCU reset key.

Regards,

Lalit Shah

    Your development board CANNOT have a pull up resistor or cap on the /reset line and must supply Vcc on pin 2 back to the devlopment board side of the level translator on the RF04. The problem with the pull up is the bi-directional level translator (ST237) sees the voltage and incorrectly sets it's direction as a input from your board preventing it from reliably (some times it works if only for a while)  driving the /reset on your board.

    Hi Stewart,

     

    Thank you very much for your suggestion.

    I have removed Pull up resistor and capacitor at reset pin and now my development board successfully gets detected with both boards.

    Please note that the comment about the cap/resistor on the RESET line is only true if you connect your own development board directly to header P14 on the SmartRF04EB. We recommend that you use the SoC Debug Plug-in board (included in the kits) as explained in e.g. the CC1111/CC2511 USB HW User's Guide, chapter 5. Then you can have the RC filter on the reset line on your dev board.

    Is the SoC Debug Plug-in board  available separately for those of us that bought our kits before it was available?

    The board is not available separately. However, if you have one of the CC1110/CC2510/CC2430DKs and do not have the SoC Debug Plugin board, TI should be able to provide you one. Please contact TI support or your local TI representative.
