Error: L6915E: Library reports error: __use_no_semihosting was requested, but a semihosting fputc was linked in

[Paul]

I am working on SDK V10.0.0 because I need S310 softdevice. I like SEGGER_RTT I used in SDK V11 and V12.

But I got the Error in the subject line. I had to uncheck use_microlib to get the linker to pass.

I have project V11 and V12 using Segger_RTT with use_microlib checked, no problem. I even found an example in SDK V10, ble_app_hrs_rscs_relay_pca10028 will pass the linker with use_microlib checked.

I compared ble_app_hrs_rscs_relay_pca10028 (SDK V10) and my project, I couldn't find the reason why the example can pass with "use_microlib" checked, but my project can only pass with "use_microlib" unchecked.

It seems to me that I missed some simple setting somewhere.

Thanks

Maybe it has something to do with:

#ifndef NRF_LOG_USES_RTT
#pragma import(__use_no_semihosting)
#endif

Have you defined NRF_LOG_USES_RTT?

[Paul]

I have "NRF_LOG_USES_RTT=1" in the project option.

Make sure I state the link error correctly:

linking... .\Objects\DXPL02.axf: Error: L6915E: Library reports error: __use_no_semihosting was requested, but a semihosting fputc was linked in

Hmm. I just followed this without unchecking MicroLIB, seems to be working fine. Added it to the ANT broadcast_tx example.

So what do you think is causing my link error?
