[En-Nut-Discussion] build problem concerning USART

[Jungeol Chun]

I had a problem building Nut/OS using configurator.
When I tried to build OS, it returns an error message like this:

avr-ar: creating libnutos.a
C:/ethernut-4.2.1/nut/dev/usart.c: In function 'UsartIOCtl':
C:/ethernut-4.2.1/nut/dev/usart.c:844: error: unable to find a register to

I used Nut/OS configurator v1.3.1 and WinAVR(avr-gcc), NutOS 4.2.1 and
Ethernut20a configuration file.
Is there anyone having a solution?

Thanks in advance.
