S110 EK demos not working after upgrades

[Lee Livezey]

I upgraded to: Keil V5.11.1.0 J-Link 4.90 nRFgo Studio 1.17 S110_nrf51822_6.0.0

The blinky demo works fine, but s110 demos like the ble_app_hrs won't advertise. LED 0 doesn't blink, and MCP 3.6 using the PCA1000 dongle won't discover it. They're will discover my iBeacon demo kit so I know they're working.

My PCA10001 EK board is V2.2.0 with an nRF51822QFG0-1342AA

Keil had the IROM1 address = 0x16000, which I changed to 0x14000 per nRFgo studio and the S110 migration notes. Didn't fix it. I've tried both the Keil 4 legacy apps, and the Keil 5 apps without luck. Given blinky works, and the hrs app worked before my upgrades it doesn't seem likely my hardware has failed. But after fighting this for over a day I'm out of ideas.

Does anyone have a suggestion I could try?

Thanks in advance!

Hi

When upgrading to S110 v6.0.0 you should use examples from nRF51 SDK v5.2.0, which should work out of the box. To see what softdevices are compatible with what SDK's, look at the release note's for the SDK's. Are you using nRF51 SDK 5.2.0?

Update 23.9.2014:
Yes the IROM address should be 0x14000

As a result from your comment, I realize now that the nRF51 SDK v5.2.0 is currently missing on our web site. I therefore attach a copy of it here. It is however available as an installation file here. The SDK v5.2.0 is preferred to use with softdevice S110 v6.0.0 as it is the latest SDK compatible with that softdevice, even though SDK 5.1.0 is also compatible with S110 v6.0.0.

Stefan,

I don't have SDK 5.2. I have SDK 5.1 and SDK 6.1. Only SDK 6.1 and S110 6.0.0 are available for download on my Nordic page. Also, for S110_6.0 should IROM be set to 0x14000 in Keil?

Stefan, SDK 5.2 did the trick. Now all works as advertised. Thank you! Is it too early yet to start using S110_7, and where is that download? Other users viewing this post please note that you still have to change the 0x0800 to 0x2000 in Cortex J-Link driver setup under Keil to avoid the "insufficent RAM" error when flashing.

Hi Lee. It is not too early to start using S110 v7, it is already in production version. You will have to use either nRF51 SDK 6.0.0 or nRF51 SDK 6.1.0 if you use S110 v7. You find all of the downloads on the nRF51822 page, "downloads" tab, including the S110 v7. Here is a direct link
