nRF5340 MDK

Hello,

With the latest version of the nRF5340 MDK I am getting the following linker errors (below), and don't understand why they should turning up.

Best regards

Hello,

Did you also update your linker script to include the updated https://github.com/NordicSemiconductor/nrfx/blob/master/mdk/nrf_common.ld file from the MDK? This file appears to include the missing sections that the linker is complaining about.

Best regards,

Vidar

Hi Vidar,

Thanks for the answer. I wasn't getting an error about it beng missing - normally this would happen in the link phase if it was  not found. In the meantime I changed a couple of other things and the problem went away. I need to investigate the reason for this when I get some time since I'm not convinced.

Best regards,

AGJ

Hi,

I'm not sure what caused this, but the varibles that were not found during linking (__data_end, __data_load_start,..) are supposed to be defined by the nrf_common.ld script.

Best regards,

Vidar
