Getting Started with nRF51422 (Keil V5.18A w/ S310)

[Daniel Blesener]

Hi, I am having some issues. Just getting started with the nRF51422, so forgive my being a bit "green." 

Background: Testing with nRF5_SDK_12.3.0_d7731ad, Keil V5.18A on the demo board PCA10028.

I thought this would be plug and play? When programming with any example, nothing happens? I am using J-Link LITE CortexM from Segger to program/debug.

I am attempting to run the "blinky" program, among other programs...nothing special. The programming is successful...but I never get to the first break point. When trying to stop the debugger, it always has the "run" button available to be pressed but never stop, not matter how many times I click it.

I have been struggling with getting started for a couple days now...does anyone have any reading they would recommend and also any idea of how to get these basic example programs running? 

Thanks,

D

Please refer to "nRF51 Series IC revisions compatibility with SDK and SoftDevices" The S310 is not compatible with SDK 12.3. If you are using S130. That's ok.

You have indicated you are using a J-LINK Lite. Have you tried just using the debugger that is built into the nRF51-DK?

Hi, thanks for the reply. I am still having some issues - sorry for the delayed response. I was pulled onto another task for a bit. Looking at your table, how do I know what revision of the IC I am using?  I do not see an indication on the IC.

The part number I see on the IC is "N51422 QFAAF0"

I found this doc though - http://infocenter.nordicsemi.com/pdf/pcn_093_v1.1.pdf

Also...I removed the installed SDK, and installed V10. Still cannot program the example program. Well it programs...but I never hit a break point.

Trying to run this program "examples\multiprotocol\ble_ant_app_hrm\pca10028\s310\arm5_no_packs"

See nRF51422 IC revision overview. Per package marking, the device in question is Rev. 3.

Thanks! That helped.
