Blinky project builds/loads fine but doesn't actually run on nRF51822/nRFgo

ouantenna

Blinky project is opened with Keil-uVision5 Projects builds with 0 errors, 0 warnings. Project seems to load properly without issue, see output window below

JLink info:

DLL: V4.92 , compiled Sep 30 2014 09:33:42 Firmware: J-Link Lite-Cortex-M V8 compiled Jul 17 2014 11:40:12 Hardware: V8.00 S/N : 518109943 Feature(s) : GDB

  • JLink Info: Found SWD-DP with ID 0x0BB11477
  • JLink Info: Found Cortex-M0 r0p0, Little endian.
  • JLink Info: FPUnit: 4 code (BP) slots and 0 literal slots ROMTableAddr = 0xE00FF003

Target info:

Device: nRF51822_xxAA VTarget = 3.306V State of Pins: TCK: 0, TDI: 0, TDO: 0, TMS: 1, TRES: 1, TRST: 1 Hardware-Breakpoints: 4 Software-Breakpoints: 8192 Watchpoints: 2 JTAG speed: 2000 kHz

Erase Done. Programming Done. Verify OK. Application running ...

But non of the leds actually light up except for led0, which i think just comes on when the board is plugged in.

novice with nordic, help please T.T

    Did you erase the SoftDevice with nRFgo Studio yet? You got to do that first in order to run the Blinky demo. Let me know if it still doesn't work.

    I clicked "Erase all" before I tried to load/flash the successfully built example application(Blinky v5) with uVision5. nRFgo confirmed the board was connected and lists it as "Board 1", corresponding to the "1" appearing on the nRF6310 motherboard display. The application is stated as "running.." in the Keil uVision output window after "load" is clicked. I tried adjusting the nRF51822 P1 connector/jumper between 32kHz and I/O options; neither worked. And I have read all of the corresponding pdfs for nRF51822, nRFgo and nRF6310. I'm going to try Stian's suggestion to flash the program from nRFgo Studio rather than Keil uVision and report back. Any other suggestions/screen shots are welcome and appreciated!
