Will there be any recommendations on how to avoid a mistake clknode_init_parent_idx: Invalid parent index 5 for clock sclk_sdmmc You will offer some patches. I am ready to try them. =D0=BF=D0=BD, 28 =D0=BE=D0=BA=D1=82. 2019 =D0=B3. =D0=B2 16:21, Emmanuel Va= dot <manu@bidouilliste.com>: > On Mon, 28 Oct 2019 14:10:32 +0100 > Michal Meloun <meloun.michal@gmail.com> wrote: > > > > > > > On 28.10.2019 13:23, Emmanuel Vadot wrote: > > > On Mon, 28 Oct 2019 12:59:30 +0100 > > > Michal Meloun <meloun.michal@gmail.com> wrote: > > > > > >> > > >> > > >> On 28.10.2019 12:10, Emmanuel Vadot wrote: > > >>> On Mon, 28 Oct 2019 13:57:57 +0300 > > >>> Sleep Walker <s199p.wa1k9r@gmail.com> wrote: > > >>> > > >>>> Hi All! > > >>>> > > >>>> On Khadas-EDGE-V > > >>>> > > >>>> - mainline uboot U-Boot TPL 2019.10-rc3 > > >>>> - bootup from SD > > >>>> - eth OK > > >>>> - uart OK > > >>>> - emmc OK > > >>>> - sd OK > > >>>> - USB 2.0 OK > > >>>> - USB 3.0 OK > > >>>> - USB HID OK > > >>>> - USB DISK OK > > >>> > > >>> Good to know that everything is working on this board too. > > >>> > > >>>> > > >>>> On Rock Pi4 > > >>>> > > >>>> UEFI booting, very cool. > > >>>> > > >>>> But I can not log into the console. > > >>>> > > >>>> it seems it keeps rebooting. > > >>>> > > >>>> Here is the log: > > >>>> https://pastebin.com/JFX7Ssnz > > >>> > > >>> This is known.
