PCA10000 and SDK 11

[Lee]

I'm trying to build the blinky example in SDK 11 and load it onto a PCA10000. I'm using the make file in PCA10031/blank/armgcc and am building this under linux. If I use blinky_blank_pca10031.hex which is in the hex directory, then I can load and run this using JLinkExe. Can anybody help explain what I am doing wrong. Thanks

Thanks for responding. My dev machine is running Ubuntu 15.04. I have downloaded and installed the SDK11, J-Link tools, and the armgcc tools and I am using the PCA10000. My aim is to use the blinky example to make sure that my dev environment is working correctly and also program the PCA10000. In the SDK, I navigate down to:

~/SDK11/examples/peripheral/blinky/hex

I then run:

JLinkExe -device nRF51

This allows me to connect to the PCA10000.

I then:

loadfile blinky_blank_pca10031.hex

I then run erase, then enter r, then g (as per devzone.nordicsemi.com/.../7). The LED on my PCA10000 changes colour as I would expect so I can see that ~/SDK11/examples/peripheral/blinky/hex/blinky_blank_pca10031.hex and my steps to program it to my board and run it are working correctly. I exit JLinkExe.

I then navigate to: ~/SDK11/examples/peripheral/blinky

I modify main.c to change the delay in order to get the LED to flash quicker (again, this is merely to prove my dev environment).

I save the file then navigate to:

~/SDK11/examples/peripheral/blinky/pca10031/blank/armgcc

I then run:

make

This generates a directory called _build and everything appears to build correctly. This contains .hex .out .bin .map and some other files from the make process. I navigate to:

~/SDK11/examples/peripheral/blinky/pca10031/blank/armgcc/_build

I then run:

JLinkExe -device nRF51

I then:

loadfile nrf51422_xxac.hex

I then erase, enter r, then enter g. Nothing happens. No flashing LED, flames, sparks or explosions.

I assume that blinky_blank_pca10031.hex was generated using IAR or Keil and so can't really tell much from comparing the .hex files other than to say that they're both very similar in size.

I have tried to copy:

~/SDK11/examples/peripheral/blinky/pca10031 to ~/SDK11/examples/peripheral/blinky/pca10000

I have changed any references of pca10031 to pca10000 and rerun the make file but with no success.

Am I missing a step or am I not editing the correct files? Any help is much appreciated.

Thanks.

You first loadfile and then you erase the chip? Have you tried to run a self build hex file, without modifying the source? (just to make sure, that your process is working)

[Lee]

What do you mean by run a self build hex file?

[Torsten Robitzki]

Take the original source, build the hex file from source and try to run it. Just to make sure, that your code changes are not the reason, for the failure.

I will try it, but I am only changing:

nrf_delay_ms(500); to nrf_delay_ms(250);
