Okay, I see, thanks.

The problem is not in the SoftDevice, the problem is that modules in the SDK(including the SoftDevice-handler module in this case) are trying to print with the NRF_LOG module because the NRF_LOG_ENABLED flag is set to true. If you remove the "NRF_LOG_INIT()", you also need to set the NRF_LOG_ENABLED to 0.

Not sure. But since the softdevice is not recompiled anyway, would it have any effect in this case?

After removing "NRF_LOG_INIT()", did you also set NRF_LOG_ENABLED to 0 in sdk_config.h?

Yep, that is the SDK I am using. The softdevice_enable() now prints

**SDH:INFO:sd_ble_enable: RAM START at 0x20002168
SDH:WARNING:sd_ble_enable: app_ram_base should be adjusted to 0x20002128
SDH:WARNING:ram size should be adjusted to 0xded8**

So I assume those print outs will fail if NRF_LOG is not initialized. When I adjust those RAM values correctly, it still prints

SDH:INFO:sd_ble_enable: RAM START at 0x20002128

So maybe NRF_LOG_INIT() is needed even then?

I need to check that. You are using SDK 12.0.0?

It looks like NRF_LOG_INIT() must be called in order to get softdevice working. This is a bit bad dependency.
