What is the difference between arm4 and arm5_no_packs examples in the NRF5 SDK

[AnthonyPhan]

Hi,

Within each example in the NRF5 SDK there are a number of folders including

• arm4
• arm5_no_packs
• armgcc
• config
• iar

I'm having trouble finding an explanation on the differences between arm4 and arm5_no_packs, can someone please explain this to me? Both seem to open in uVision.

I assume the IAR folders contain project files for those developing in  IAR Embedded Workbench. Is this assumption correct?

Further more what folders do i use if i want to use Seggers "Embedded Studio for ARM" as my development environment? Based on this article the latest SDK should contain examples for Segger Embedded studio. I am using NRF5_SDK_12.3.0

Hi,

Different folders are for different projects.

arm4 - Keil4 project

arm5_no_packs - Keil5 project

armgcc - gcc project

iar - IAR project

ses - Segger Embedded Studio project (available in SDK14.1 and SDK14.2)

Thanks Jakub,

Am I correct to say there are no NRF51 examples for Segger Embedded Stduio since SKD14.2 and above only support soft devices for the NRF52?

[Jakub Rzeszutko]

Hi,

Yes there are only examples for NRF52.

If you want to use Segger Embedded Studio with examples from SDK 12.3 and nRF51, you can follow this tutorial.

Hi Jorgen,

I appreciate the input. I have tried to follow the tutorial but the links to the downloads ses_nrf51_startup.s and ses_nrf52_startup.s have been down for a few hours now. Are there any mirror links to these files?
