09:29 <lucastanure> Hi, I am trying to get started with Vim3 a311d (V12).

09:29 <lucastanure> I downloaded VIM3_Ubuntu-server-focal_Linux-5.7-rc7_arm64_SD-USB_V0.9-20200530, flashed into an SDCARD and everything works. I can boot from that SDCARD.

09:29 <lucastanure> But when I try to build my own kernel and replace into the SDCARD, VIM3 fails to boot and boots from internal emmc.

09:29 <lucastanure> Build steps:

09:29 <lucastanure> export CROSS_COMPILE=aarch64-linux-gnu- #gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu

09:29 <lucastanure> git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

09:29 <lucastanure> export ARCH=arm64

09:29 <lucastanure> git checkout origin master

09:29 <lucastanure> make defconfig

09:29 <lucastanure> make Image dtbs modules

09:29 <lucastanure> scp arch/arm64/boot/Image root@192.168.77.35:/boot/zImage

09:29 <lucastanure> scp arch/arm64/boot/dts/amlogic/meson-g12b-a311d-khadas-vim3.dtb root@192.168.77.35:/boot/dtb.img

09:29 <lucastanure> scp -r ./modules_install/lib/modules/5.9.0-rc6+ root@192.168.77.35:/lib/modules

09:29 <lucastanure> My uboot env: https://pastebin.com/RqzJHny8

09:29 <lucastanure> My kernel config: https://pastebin.com/WiYUQYTm

09:29 <lucastanure> My uboot boot log: https://pastebin.com/dsuWVXNy

09:29 <lucastanure> There is anythine espcial in Vim3 that I not doing?

09:29 <lucastanure> I should only replace kernel and dtb image, copy the modules and the board should into the new kernel using the SDCARD.

09:29 <lucastanure> I cant see why it would fail on booting from the SDCARD.

09:29 <lucastanure> Any help is appreciated.

09:43 <xdarklight_> random observation: "ERROR: Did not find a cmdline Flattened Device Tree"

09:43 xdarklight_ is now known as xdarklight

09:44 <lucastanure> erasing emmc from linux did not solve : dd if=/dev/zero of=/dev/bootloader

09:44 <lucastanure> erasing from uboot did solve "store init 3"

09:44 <lucastanure> thanks

09:45 <lucastanure> Now I can boot Linux version 5.9.0-rc6+

15:28 <rtissera> hello

15:29 <rtissera> I'm trying to get sound (HDMI of jack) working on Odroid N2 mainline kernel 5.8.12

15:30 <rtissera> it seems it's not working out of box, is it a known issue ? I tried playing with a lot of device-tree patches and so on but no luck

15:30 <rtissera> snd_soc_meson modules and axg are loaded but

15:30 <rtissera> my /proc/asound/modules is empty

15:30 <rtissera> do you think it is alsa userland side or a kernel issue ?

18:51 <tuxd3v> hello all,

18:51 <tuxd3v> Does any one knows any board other than ViM3 with A311D SoC?

19:40 <narmstrong> tuxd3v: afaik no

19:52 <tuxd3v> narmstrong, A311D seems to be the best Soc around in the sbc segment, maybe not the best suported, but the fastest, it would be nice to see others using it..

19:53 <narmstrong> tuxd3v: we do our best to support it correctly :-)
