Impossible to load .bin into PCA10040

[Javier]

Hi!

Friday I can load the binary into PCA10040 (blinky example) ands works well. But today I load de binary but not works, nothing happen.

I'm used this example /Nordic/nRF52/examples/peripheral/blinky/pca10040/blank/armgcc

and other this (softDevice s132) /Nordic/nRF52/examples/peripheral/blinky/pca10040/s132/armgcc

Which maybe the mistake?

Javier,

I have had similar problems when I try to use the S132 SoftDevice. Sometimes it seems to be necessary to completely erase the board, other times not. I use JLinkExe on my Linux system to flash and erase the nRF52. Here are a few links where I describe my problem and the solutions that have worked for me, they may help you:

Thanks Ladasky,

I have installed JLinkExe but I cann't to connect to the board, I get this error:

javi@PC:~/Development/Nordic/nRF5x-Command-Line-Tools_9_0_0_Linux-x86_64/nrfjprog$ JLinkExe -device nRF52

JLinkExe -device nRF52

Connecting to J-Link via USB...FAILED: Can not connect to J-Link via USB.

I'm going to try add a dev rule in my Linux installationto see if it solves the problem.

Greetings

PD: I have the PCA10040 connected to PC via USB and Power ON

I think that the FIRST time that you run JLinkExe, you should not use the "-device nRF52" option. JLink updates the SEGGER firmware on the board when you run it the first time, and that is when the device ID is created. Starting with the second time you run JLink, you can (and should) use "-device nRF52".

In other machine with Ubuntu Xenial I installed JLinkExe and the first time I executed so, JLinkExe , the second time I run JLink with -device nRF52 but I get the same error:
