@facchinm @Rocketct seems there is an issue reading analog pin A1 (PA1_C) while ethernet connection is up (PA1 pin connected to nINT/REFCLK0). If i do this, communication hangs. I thought it is related to this :

but SYSCFG_PMCR configuration is OK. Is this something we already know? anyway i need to better investigate.

For sure it's worth investigating; maybe the analog apis in mbed core trigger a flip in the SYSCFG_PMCR register when called for the first time (the _C handling has been reworked by ST after we did the first round of patches for the h747)

made some measurements and clock looks ok while reading PA1_C analog input... still investigating.
