Blinky example of MDK CMSIS Issue

[William.SportsArt]

Hi support team,

My environment:
nRF52-DK / PCA10040 / s132   (central x 1)   by   \nRF5_SDK_17.1.0_ddde560\examples\ble_central\ble_app_multilink_central
MDBT42Q-DB   (peripheral x 3)   by   \nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_blinky
SDK 17.1.0
MDK IDE-Version: V5.38.0.0

When I open the ble_app_blinky project, the project list on the left side, CMSIS is red.
I checked the pack installer, and the pack status is as follows.
How do I fix this CMSIS issue?

This pack installer has always being creating some incompatibilities in Keil, is there anyway you can try your project with Segger Embedded Studio or even better use our latest nRF Connect SDK if you are still in prototyping phase of your project?

Hi Susheel,

Thank you for your reply.

That is working after resuming the source code at last.

But, I don't understand why the same source code has the CMSIS issue?

Probably a device family pack is missing to be installed? Not sure. But glad that it is working now.

Hi Everyone,

The issue is solved.

I deleted the project and then copied the new one to build again, there are no red CMSIS.
