<p>Tak mam pokracovani serialu, zkompiloval jsem distribuci, pak
extra kernel a upravil DT zatim aspon castecne - system nabehne
a funguje ale je potiz s ethernetem zase</p>
<p>V u-boot mam nastaveny resetovaci pin pro PHY, tam korektne
funguje, normalne je v 0 protoze ethernet je normalne neaktivni</p>
<p>ðernet0 {<br>
status = "okay";<br>
pinctrl-0 = <ðernet0_rmii_pins_a>;<br>
pinctrl-1 = <ðernet0_rmii_pins_sleep_a>;<br>
pinctrl-names = "default", "sleep";<br>
phy-mode = "rmii";<br>
max-speed = <100>;<br>
phy-handle = <&phy0>;<br>
nvmem-cells = <ðernet_mac_address>;<br>
nvmem-cell-names = "mac-address";<br>
<br>
mdio0 {<br>
#address-cells = <1>;<br>
#size-cells = <0>;<br>
compatible = "snps,dwmac-mdio";<br>
phy0: ethernet-phy@1 {<br>
<b>reset-gpios = <&gpiog 0
GPIO_ACTIVE_LOW>;</b><br>
reg = <1>;<br>
};<br>
};<br>
};</p>
<p><br>
</p>
<p>Kernel ovsem na to reset-gpios evidentne kasle a ve zdrojacich
jsem to pro predpokladany HW taky nenasel, ale jeste do toho moc
nevidim. Pin zustava v 0 a ani se nehne, kdyz ho v u-boot
nastavim na 1 z prikazove radky a nabootuju, tak vydrzi na 1 a
ethernet normalne funguje (zkousen ping)</p>
<p>Co s tim? Je to vlastnost? Co udelat v DT aby se pin spravne
pouzil pro reset, nebo aby se aspon ve vhodny cas hodil do 1?<br>
