unable to build software using Keil MDK

[Ruuddb]

L.S.,

I'm trying to build an "Arduino" port for the nrf52840 (Seeed board).

When building an example I'm getting the following errors during the link phase:

.\Objects\nrf52_SoftwareSerial.axf: Error: L6218E: Undefined symbol SaSi_LibInit (referred from adafruit_nrfcrypto.o).
.\Objects\nrf52_SoftwareSerial.axf: Error: L6218E: Undefined symbol SaSi_LibFini (referred from adafruit_nrfcrypto.o).

What do I need to do to resolve this?

Okay, then I'm afraid there is not much we can do on our end, since we're not familiar with SDKs that aren't ours nor Keil v6 as we're only maintaining the v5 solution, SEGGER solutions and the Zephyr based nRF Connect SDKfor the time being.

Best regards,
