STM CircleOS forum / Partial remap on TIMER3 CH2 in STM103 high density

Hello,

I have a trouble with TIM3CH2 : the exact same timer programming gives the following results :

no remap : correct output on PA7
full remap : correct output on PC7
partial remap : no output on PB5

In the last case, the IO programming is

AFIO= 0x000018C0
PB= 0xDD98B400

for AFIO MAPR and GPIO CRL.

Has anyone ever encountered such configuration and made it work ?

I was able to test the 3 possibilities on my prototype but unfortunatly the board is routed so that only PB5 can be used for the function I am programming.

Thanks.
