Keil Error "Cannot read RTE data from project file RTE is not enabled"

[alex_u]

Hello,

when I open any example Project from https://www.nordicsemi.com/Products/Development-software/nRF5-SDK with Keil MDK v5, I directly get the Error Message "Cannot read RTE data from project file: RTE is not enabled". After that the project loading is aborted and I am presented with just µVision without any opened project. How can I fix this?

Hi Alex,

I have not come across this before. Which SDK version do you use?  Do you have the nRF Device Family pack installed (check in Project -> Manage -> Pack installer)? And what does it look like if you check Project -> Manage -> Run Time Environment... ? It should look something like this automatically if you open a SDK 17.1.0 project:

Hi,

I use nRF5_SDK_17.1.0_ddde560 with the example located at examples\ble_peripheral\ble_app_blinky\pca10040\s132\arm5_no_packs. My Keil installation is Version 5.30. When I try to open the project it does not open but presents me this error:

After clicking "OK" I cannot access the Pack installer and the Run Time Environment, because the project could not be loaded.

This happens only for nrf52 projects. All our other projects open without any issues.

regards

Alex

Hi Alex,

I see. Looking t the lower screenshot it does not look like the project was opened, probably due to the error message. I don't understand why you got that, though. How did you open the project? And does it help using a clean Keil install? (I don't have very specific suggestions unfortunately, as I have not been able to reproduce or find older descriptions about this issue).

[alex_u]

It is a clean installation of Keil. Our IT Department uses "--batch-install" flag to install it on my PC. See https://www.keil.com/support/man/docs/uv4/uv4_ov_install.htm for reference.

I see. How did you open the example project? Can you try simply to double-click on the .uvprojx file?

[alex_u]

I did exactly that

I see. I have asked my colleagues but have not found anyone having seen this before or with any suggestions, so we are unfortunately not able to suggest a way to solve this at the moment. I recommend you contact Keil support, hopefully they can say more.

In the mean time, perhaps it is an alternative to use another one of the supported tooclhains or IDEs, for instance Segger Embedded Studio? This can be used free of charge for any project where the target device is a nRF.

I already contacted Keil support. They could not reporduce it either and sent me to you...

Unfortunatly using another toolchain would mean that I need to port my exisitng projects to the new toolchain. Thats quite alot of work for just one error that somehow came up and noone knows of.

But it seems like it is the only option available.

Thanks for your help.
