Hi,
Just received my nrf51 DK board today and was trying to load the blinky example from my Mac (El Capitan ). It did not seem to work.
I first configures the compiler path as follow in Makefile.posix:
GNU_INSTALL_ROOT := /Users/developer/Tools/Compilers/gcc/gcc-arm-none-eabi-4_9-2014q4
GNU_VERSION := 4.9
After building the blinky example in "nRF51_SDK_9/examples/peripheral/blinky/pca10028/armgcc", I erase the flash on board with the folvogin command:
w4 4001e504 2
w4 4001e50c 1
sleep 100
r
exit
The erase commands seems to be executed correctly, with the following output:

exit
Here is the output:

However, after the flashing, there is no change on the board. The less do not blink. I have no idea why this did not work. I also have the old pca10001 board with nrf51822, which I was able to successfully upload the blinky example with idk 6.0.1. Did I do something wrong? Can that be the OS X version I am using (el capitan)?
I also check state after each command, they are identical as follow:
J-Link>h
PC = FFFFFFFE, CycleCnt = 00000000
R0 = FFFFFFFF, R1 = FFFFFFFF, R2 = FFFFFFFF, R3 = FFFFFFFF
R4 = FFFFFFFF, R5 = FFFFFFFF, R6 = FFFFFFFF, R7 = FFFFFFFF
R8 = FFFFFFFF, R9 = FFFFFFFF, R10= FFFFFFFF, R11= FFFFFFFF
R12= FFFFFFFF
SP(R13)= FFFFFFD8, MSP= FFFFFFD8, PSP= FFFFFFFC, R14(LR) = FFFFFFF9
XPSR = C1000003: APSR = NZcvq, EPSR = 01000000, IPSR = 003 (HardFault)
CFBP = 00000000, CONTROL = 00, FAULTMASK = 00, BASEPRI = 00, PRIMASK = 00
I do not know how to interpret this. If this is no change of state after uploading the blinky binary, does that mean it is failed?
It has been really frustrating after receiving the board, your help is much appreciated.
