Compute Module • Re: [CM4] Ethernet Phy fails to come up after reboot/after brief power down

Eliminating Q6 (the transistor) seems to be enough to overcome our immediate problem.

Is there any guidance on the SYNC pins? We're interested in actually using the hardware PTP clock in the future.
Our FPGAs inputs provide weak pullups at least until startup is finished (and currently at all times because the pins are unused), we could counter that with stronger pulldowns if power sequencing requirements make that necessary.

Greetings, Martin
