What is exactly mean 'arm5_no_pcack'

[jees]

I curious about that what does exactly mean 'arm5_no_pack' folder name in SDK.

I usually used or developed under uKeil5(MDK-ARM5 v5.12). What is relation with 'arm5_no_pack' and 'Pack Installer' in Keil IDE. Also, 'nRF5x_MDK_8_7_1_Keil4.msi' in nRF5_SDK_12, what is this ? Do I must install this file ?

Thanks.

Hi

You normally do not need to install this msi file as it is for Keil4, and you have Keil5, so installation of the right MDK should happen pretty much automatically when you use Keil5, see this thread.

We used to support Keil pack but stopped supporting it from nRF5 SDK 11 as it turned out to cause more trouble that actual advantage. We used to have two folders in the SDK, pack and no_pack, but now we have only no_pack. So the naming arm5_no_pack is kind of a legacy from when we had both pack and no_pack versions of the SDK.
