I'm using the STM32F446ZE.
I'm using PA11 and PA12 for USB FS DM and DP, but I don't need PA8 as SOF, I need it as a simple output.
USB is runing fine only if PA8 = 0 !
If I set PA8 output to 1, the USB disconnects.
It looks like the PA8 is in Alternate function mode, but after double-check, the PA8 mode is in Output mode ( MODER8 = 1, AFR8 = 0 ).
Did someone already faced this issue ?
Thanks and best regards,
