mount -o remount,rw /flash to mount it with read/write permission
already done … it s the step before in the guide…
oh, I missed that no such file…
Is it installed on internal?
yes it is…
Enter this and show the output:
fdtget /flash/dtb.img /ethernet@0xc9410000 wol
mount -o rw,remount /flash
fdtput -t i /flash/dtb.img /ethernet@0xc9410000 wol 1 && sync
thx i did it but now when i try writing the binary to sektor 0 of the micro SD card at /dev/sdc i had a message that /dev/sdc was unexpected…
i try then to upgrade the u-boot and now the box is bricked again…
SO i will test the Portisch command later and show the output…
fdtget /flash/dtb.img /ethernet@0xc9410000 wol
0
~ # mount -o rw,remount /flash
~ # fdtput -t i /flash/dtb.img /ethernet@0xc9410000 wol 1 && sync
~ #
nothing else append, so i assume that wake on lan wake up is enabled
now i had to create the sd card and write the u-boot on sektor 0 but two times i try two times i fail…
i m using a windows 7 pc to write the u-boot on sd card…
I use also main time Windows but for this I use a Linux virtual machine. I don’t know what tools on Windows you can use to make it bootable.
You do realise that if you take the SD card and put it in your Windows PC that /flash is the (fully accessible) visible partition of the bootable SD card, don’t you?
ah ok , i’ll try with virtual box… do you know a light linux version to do it ?
thx , this part of the issue is already solved…
I use Ubuntu 18.04 server. just download the iso, install it to a VM. After install connect the SD card reader hardware to the VM, insert the SD card and do fdisk -l. It will show sdc, sdb or something else. Then do a dd to sector 0 of the shown sdX. You don’t need to mount the SD card.
Hi.
I’ve been using this modified uboot in my MiniX U9-H for a long time and I had not realized that the USB do not work. Only USB-OTG works, the rest do not go.
I have done several tests with the original and modified uboot and I have collected the logs by UART.
It seems that the kernel recognizes the USB (with both uboots), but with modified there is no power on USB, with original one there isn’t any problem (if checked with a HDD attached on USB ports).
I have done the tests with the nightly of coreelec + ps3 controller attached in USB port 2.
Here are the log.

@Portisch uboot --> https://pastebin.com/tji5FuCC
This sounds a gpio needs to be switched on to enable USB power. But as there is no schematic or any other description a research by trial and error is needed.
You feel able to do electrical measurements on the PCB/USB port?
which guide did you follow? i need CEC to work. thank you
I tried with windows ubuntu. ( I have no idea what i am doing)
but have problems: make CROSS_COMPILE=aarch64-linux-gnu-
make[1]: aarch64-linux-gnu-gcc: Command not found
/
… i ran out of nerves 
is there a easyer way to make this CEC to work ?
like just flash a boot img file or new kernel or whatever? If anyone has done it. for minix neo u9 can I just use his files ?
thanks! I am willing to pay for solution.
Just use the ready to use binary: https://github.com/CoreELEC/u-boot/releases

Can this be done with an USB flash disk instead of micro SD card?
And should there be a problem if the emmc is still on Android (with root access)?
I think the box will not boot from a usb stick - only from eMMC or SD. But I never tried. And I do have also Android on the eMMC and CE on the SD. You just make a update of the bootloader.
