OSC'clock:'(necessary'step!)'
Currently%there%are%are%two%working%possibilities:%MCO%from%ST=LINK%or%HSE%on=board%oscillator.%
%
Solution'1'MCO'from'ST?LINK:%Check%your%serial%number%on%the%backside%of%your%board%(see%pho to) :%
If%your%n u mber%is%“MB1136 %C=02”%or%higher,%than%you%are%ready%to%go%to%the%next%step.%
If%your%se ria l%nu mber%is%“MB1136 %C =02”%you%need%following%changes:%
Desolder%the%0=Ohm=resisto rs%%%on%SB55%and%SB54%(bottom %righ t)%to%cut%th e%trac e.% %
Solder%a%little%bridge%on:%SB16(MCO)%(top%left)%and%SB50%(bottom%middle)%

Solution'2'HSE'oscillator'on?board'from'X3'crystal:'Please%consider%the%reference%manual%for%further%
