Newbie having trouble getting started...

[eq]

Hello, I just received my BMD-200 eval board today and cannot get any of the examples working. I started out trying to get blinky to work using GCC and the make files provided. I am able to successfully build the projects. The _build directory has the .hex files. It is not clear what the next step should be here. make soft_device seems to just load the Soft Device so how does the example get loaded in this paradigm? What dictates where in memory it gets loaded in the GCC paradigm? Is this important?

After many attempts, I gave up on the above method and tried using nrfGo Studio. I loaded the 110 Soft Device (I am on the latest SDK version 8), and then loaded several peripheral examples. None of them run.

I gave up on this method and downloaded the Keil tools. I followed the instructions in the manual by first using nrfGo Studio to load the 110 Soft Device, and then moved over to the Keil tool. Made all of the configuration modifcations, downloaded custom_board.h, and the project builds successfully. It even seems to download to Flash successfully but it won't run. blinky does not blink and none of the ble peripheral examples advertise, so I know its not working.

I'm not sure what to try next. Can you please let me know what I am doing wrong based on the above. I don't care which method I use; I just need one that works.

Any help would be greatly appreciated.

Thanks.

I suggest that you check the chip revision as well. Chip rev 1 may not work with SDK8.

Here is makefile.common:...it seems to be failing here but the error message doesn't tell me where it broke. Can you tell what the problem is? I'm unfortunatley not a makefile expert, but once I get this example running I will be out of your hair..:-)
