This is a photo of Your Board ? What is the marking of memory eMMC ?

[Jefken3]

Yes this is my board, where do I find this marking?

[Jefken3]

Thinking in buying one like these; http://nl.aliexpress.com/item/9892GJ...8.4.189.nmtF4B

[balbes150]

On the chip is something like KLM8G1WEPD-B031 ?

[Jefken3]

Yes, affirmative, that 's correct! "KLM8G1WEPD-B031"

So you can try to use the contacts that are indicated for the i7. I compared the photos, everything points to the fact that these contacts are the same. Not something terrible should happen if You for a few seconds will close these contacts. They can be careful not to close a large flat screwdriver or a knife for the securities. For small contacts, I ordered that.

I recommend using this procedure. 1. Turn off the power from 220 volts. 2. plug in card 3. to close the contacts 4. turn on the power 5. wait 2-5 seconds with closed contacts 6. open contacts (NOT power off) 7 to wait some time (20-40 seconds) to start system from SD card. On the SD card needs to be recorded, the system shall be recorded in the correct DTB file. Additionally, must be stored a boot loader. By the way, You when I recorded previously on the SD card and the bootloader, the DTB file changed on its own ? Do You still have the SD card with which You ran Linux ?

First twice commands "sudo dd if=u-boot.bin.sd.bin",... than on root I copy , aml_sdc_burn.ini, aml_upgrade_package.img, u-boot.bin.sd.bin and additionaly "dtb.img"?
I 'm sorry, I used the Linux card to make the rescue card, to do the procedure I' ll first off all have to arrange me some magnifying glasses in order to continue. Regards.

Hey guys,

So I had a similar problem when I bricked my Telos in this manner. I compiled the uboot image and used dd to write the image directly to the SD card, actually overwriting the filesystem on the card. For whatever reason it would not read the SD card from anything other than offset 0 on the device. A FAT formatted card writing the image after the partition table did not work.


It did boot from this however the uboot build from the amlogic source wouldn't load an OS, it seemed to have an issue with the fact the Telos has 2GB of RAM and the u-boot image was expecting 1GB (even with the correct DTB file loaded). I had to swap out the SD card with another one then I flashed the e-mmc bootloader from the default image for the Telos from the Tronsmart website using the u-boot serial console. This would then boot correctly.

I would very much suggest trying to get the serial console to work, that board does appear to have the correct headers but you will need a 3.3V serial adapter from **** or similar.

You can do so. To record on the SD card you already have (proven) way of Linux. Which You ran earlier. To write on the same SD card boot loader (two teams, "dd"). To try to boot from this card (without contact closure).

If you use the files (the link that I pointed out earlier) and install the bootloader two commands (exactly as written). The partition table is stored. SD card to become bootable. It is tested on several different models with 1Gb and 2GB of RAM. The partitions on the SD card are visible on a PC with Linux. Can download any image, install the bootloader and check. I suggest not to connect the 3.3 V UART adapter. I recommend to only use three pins Rx Tx GRN. The adapter will get power from USB.


p/s/ I have a Spot on i7 has stopped working internal memory eMMC. Now I use it with an SD card, on which is written the Linux and the boot loader. Everything is fine starts and runs.

Hi,
I tried to download telos_ubuntu_odroid2c.7z.(2.3GB) from the link, but there is only OpenELEC files. Where can I find the ubuntu package?
Thx.

Ubuntu and Armbian - images with automatic detection and download of need the dtb file (depending on the model of the console). For this automatic function you need to activate the multi-boot latest versions of the file aml_autoscript for a particular model. If for some reason auto-detect the dtb file is not working, you need to manually copy the dtb file to the root of the FAT partition of the carrier.

Thanks a lot, but it is a .xz file, not zip, rar or any zipped package. As far as I understand I need the telos_ubuntu_odroidc2.img file for HDD Raw Copy Tool in order to prepare the bootable SD card. I have Vega S95 Telos hardware.

[Pauz]

OK, I could unzip with 7z program. I hope this ubuntu_multi_dtb_v3_20160625.img is ok for Telos.
