Running Linux From SD Card or USB Flash Drive - Using Balbes150 Method And Files.

[Nebojsa]

How to do that?

[balbes150]

Write one of these images to the SD card and show the UART output when the SD card is inserted in TV box turn on.

https://yadi.sk/d/_UBSKeaT3ZeHun

[Nebojsa]

Used first image, Armbian_5.44_S9xxx_Debian_stretch_3.14.29_icewm_20 180729.img, unpacked it with 7z to get .img file,
write it to SD card with Win32DiskImager, insert card to box, turn on the box. UART output is the same as before:

GXM:BL1:dc8b51:76f1a5;FEAT:ADFC318C:0;POC:3;RCY:0; EMMC:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:1;E MMC:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:2;EM MC:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:3;EMM C:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:4;EMMC :800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:5;EMMC: 800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:6;EMMC:8 00;NAND:81;SD:0;READ:0;CHK:AA;USB:8;

[balbes150]

What does the UART console show if you run the flashing process through the USB Burn Tool ? What shows the UART when running the card with Coreelec (the output from which you showed earlier) ?

[Nebojsa]

Tried with the SD card that worked before I removed the chip, UART output is the same:

GXM:BL1:dc8b51:76f1a5;FEAT:ADFC318C:0;POC:3;RCY:0; EMMC:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:1;E MMC:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:2;EM MC:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;LOOP:3;EMM C:800;NAND:81;SD:0;READ:0;CHK:AA;USB:8;

USB burning tool don't recognize the box now, had to short pins before to recognize, now it's not recognizing. UART output is the same:

GXM:BL1:dc8b51:76f1a5;FEAT:ADFC318C:0;POC:3;RCY:0; EMMC:800;NAND:81;SD:800;USB:8;LOOP:1;EMMC:800;NAND :81;SD:800;USB:8;LOOP:2;EMMC:800;NAND:81;SD:800;US B:8;LOOP:3;EMMC:800;NAND:81;SD:800;USB:8;LOOP:4;EM MC:800;NAND:81;SD:800;USB:8;LOOP:5;EMMC:800;NAND:8 1;SD:800;USB:8;LOOP:6;EMMC:800;NAND:81;SD:800;USB: 8;LOOP:7;EMMC:800;NAND:81;SD:800;USB:8;

Have another SD card and tried Armbian but all the same. Tried also to shorting pins like before, but there is no chip and that not working anymore, now box won't boot at all.

[balbes150]

The processor does not see any interface (Sd or USB). Any problems with the power supply (circuit) or PCB track.

[Nebojsa]

Yes, but how it worked when the emmc was attached to the board?
I just needed to short pins and it would boot.
Is there any chance now to short some points and make it booting again?
Power supply is good, I measured around the DC jack and have 5.0v.

Edit:

Interesting find:
I have another broken box, Beelink GT1 Ultimate and have some files that I'm experimented with, u-boot.bin.
Tried to burn the image with Win32DiskImager and put it in this box

and get some UART readings:

GXM:BL1:dc8b51:76f1a5;FEAT:ADFC318C:0;POC:3;RCY:0; EMMC:800;NAND:81;SD:0;READ:0;0.0;CHK:0;

So, the box see sd card but won't boot Coreelec or Armbian from it.
Maybe this helps to find what is wrong.

[Nebojsa]

Edit 2:

Found another .bin file, u-boot.bin.sd.bin for A95X (can't find u-boot.bin.sd.bin for my box, Sunvell T95V pro), made bootable sd card with Amlogic boot card maker and have uart reading:

Thinking, if sd card wake the device maybe it will find usb with CoreElec and boot from it, it find it but won't boot...

SUCCESS!

I found u-boot.bin.sd.bin for my box, write it to sd card with Boot card maker (not Burn card maker).
Make another usb flash drive with CoreElec from scratch, plug both sd card and usb flash to box.
Plug the power and... voila, it boots to CoreElec!

@balbes150, thanks for the help and for clarifying some things that I didn't know.
I have another question.
In this case I have to plug both sd card and usb flash for everything to work.
Is there any way to combine those two into one?
I'm Windows user and when make sd card with Boot card maker, card remains empty in Windows (looks like empty)
and cannot copy files to usb flash and make it the only device I need for boot.
Any suggestion how to do that?
Thanks.

I don't know how to implement system startup in coreelec. Libreelec and Armbian can be made to run from SD card. But for this you need to use Linux (it can be run in LIVE-CD mode on any PC) to write your u-boot option to the SD card.

[Nebojsa]

I think that coreelec is the same as libre, but if don't work I will install libre, doesn't matter.
Will make live CD or live usb with Linux, any suggestions which Linux to try?
What then, what to do when boot to Linux?

[balbes150]

You can use any LInux you like. Write the LE or Armbian image to the SD card. Rename the script "s905_autoscript"to " aml_autoscript". Copy to SD card need the file "u-boot.bin.sd.bin". Run Linux on your PC. Connect SD card to PC. Open the terminal. Switch to the "root" user mode with the "sudo su" command (a prompt with the "#" symbol should appear on the line). Run the command "fdisk l". Carefully examine the output of this command and find how your SD card is marked in this list. Execute two u-boot write commands on the SD card.

dd if=u-boot.bin.sd.bin of=/dev/<name of your Sd card in the system> conv=fsync bs=1 count=442
dd if=u-boot.bin.sd.bin of=/dev/<name of your Sd card in the system> conv=fsync bs=512 skip=1 seek=1

After these steps, the SD card will boot and have a working system.

Thanks, this works!
Made live usb with some small Linux distro, think Slack, wrote commands you gave me on prepared SD card with Libre and box boot just with that SD card.
Then I tried something else.
Made new SD card with CoreElec, then use Boot card maker to write u-boot.bin.sd.bin, just untick option "format".
I got bootable SD card with CoreElec , no need for Linux step.
So, everything is working now from SD card.
I tried to do the same with USB stick, but won't boot.
Think that boot device must be SD card.
I would like more if can use USB stick because I have couple of those that don't use, but never mind, it's important that works.
Thanks again.

USB media cannot be made bootable.
