Hi Nordic,
I am having a problem with linking against either of the gazell gcc libs (gzll_gcc.a or gzll_sd_resources_gcc.a).
I'm using Yotta (MBED) and have taken the example main_device_ack_payload.cpp straight from the example dir of the NRF51-STK v10. It says that it cannot find the references to nrf_gzll_init(), nrf_gzll_set_max_tx_attempts() etc. As you can see, it is clear that gzll_sd_resources_gcc.a is included as a lib but still it's not working...
I have tried to look at your example to understand if you are using flags that I'm not (like -lnosys). But no matter what I do it's the same thing.
Please, do you have the slightest idea why it's not finding the references?
Kind regards Anders
