MECOOL KM3 Works

[flymike]

This is not a bug, just a report of that my MECOOL KM3 (S905x2, 4G/64G/100M net) work great with meson-g12a-sei510.dtb. Ethernet/WiFi/BT all work correctly.
This TV box used to be very popular...

Thank you very much for your sharing, I will record it in CONTRIBUTOR.md and support list, have you tested him to support 5.15 kernel?

[flymike]

Yes. I'm using the latest 5.15 kernel, booted from USB3 thumb drive. Power led, Reboot and Shutdown also work properly.

Does it support writing to emmc?
Are you using this configuration?

FDTFILE="meson-g12a-sei510.dtb"
UBOOT_OVERLOAD="u-boot-x96max.bin"
MAINLINE_UBOOT="/lib/u-boot/x96max-u-boot.bin.sd.bin"
ANDROID_UBOOT=""
AMLOGIC_SOC="s905x2"

Just my 2 cents, on Mecool KM9 PRO 4G/32G/100M (which is just another name for the km3, android images work interchangeably) kernel 6.1 doesn't boot at all, only 5.15 works.

meson-g12a-sei510.dtb is unusable because the sd card keeps resetting
meson-g12a-u200.dtb has everything working perfectly including eth0, but no wlan (I decompiled the dtb and there's none, so not suprising)
meson-g12a-x96max has wlan working but eth0 crashes on a dma error, which slows the boot process quiet a lot, so not ideal

I'll try to see if I can add the wlan to the u200 dtb at some point, for now this devicetree with a usb wifi dongle seems to be the best compromise

Mecool KM9 (Not Pro) is also suitable for meson-g12a-sei510.dtb

I have the Mecool KM9 (4/32/100) and trying to boot this. I renamed u-boot-sei510.bin to u-boot.ext but it boots to Android recovery. What other steps should I take? Thanks.
