Hi Serge,
Sorry I never used GPIO provided by DWMAC IP. Obviously, I think is to
late for you to use GPIOs provided by your SoC directly. Unfortunately,
it seems to be a "perfect" chicken and eggs problem :(.
Do you have possibilty to "play" with gpio setting. I mean change
configuration of
Hello folks,
I've got a problem, which has been blowing by head up for more than three
weeks now, and I'm desperately need your help in that matter. See our
Baikal-T1 SoC is created with two DW GMAC v3.73a IP-cores. Each core
has been synthesized with two GPIOs: one as GPI and another as GPO. Ther
