Hi Adam, Thanks for your reply. env_get_location function is already declared (__weak) in: - env/env.c Override 2 times the same function, is that correct? I think can be a good solution too, declare it as __weak in soc.c and override it at board level. Some References: - https://developer.arm.com/documentation/dui0491/i/Compiler-specific-Features/--weak Let me know.
