rafaelSorel Posted December 13, 2017 Share Posted December 13, 2017 Hello, I have compiled the kernel and bootloader from: https://github.com/150balbes/build It generates *.deb for uboot, kernel and dtb files , i downloaded those file to my ubuntu installed os on my sd card, then I have run dpkg --install *.deb files and rebooted, when rebooted the box won't start, even the LED is not lighted !? , I have tried to make hard reset even I have removed the SD card and made a hard reset , the box won't start at all. I think when I have run the dpkg install command it wrotes the bootloaded into /dev/mmcblk0 which is I guess the internal emmc file. Is there any thing I could do to deblock the situation. [Edit] my box is an mxq pro 4K. Thanks for your help, 1 Link to comment Share on other sites More sharing options...
balbes150 Posted December 14, 2017 Share Posted December 14, 2017 You will have to restore u-boot in TV box using USB cable (using the firmware from the USB BurnTool regular firmware) or using the SD card with the correct u-boot. Blocking is not the right u-boot in eMMC you have to close the contacts on the chip eMMC. You recorded u-boot from another platform. You cannot use the deb package is installed with u-boot , if you are not sure what platform it was intended. Link to comment Share on other sites More sharing options...

Search the Internet for a description of the contacts of the chip eMMC for your model. With the closure which blocks the use of u-boot from eMMC. Write on the SD card image Armbian and written in the first sector of the right u-boot. Connect card. Closes the contacts. The power of TV Boxing. If you do it right, will be able to run Armbian and to fully overwrite or erase the u-boot in eMMC. Or you can use the USB cable and the program for the firmware. To turn off the power supply of the TV box. Connect the USB cable to the TV box and the PC. To start the firmware program on a PC. Select the firmware file in the program. In the program click "Start" button. To close the contacts on the chip. After a few seconds, should come firmware. Link to comment Share on other sites More sharing options...

rafaelSorel Posted December 14, 2017 Author Share Posted December 14, 2017 Well I think it is breaked once and for all, I have tested the SD , the USB burning tool with the USB male/male cable and even the serial output through the SD card reader and nothing pops up, no logs from the bootloader or the boot rom Link to comment Share on other sites More sharing options...

rafaelSorel Posted December 14, 2017 Author Share Posted December 14, 2017 Yes but if the installation is on the SD card, it will try to flash the SD card not the emmc ? Link to comment Share on other sites More sharing options...

The script cannot know where you want to install the boot loader on SD or eMMC. Link to comment Share on other sites More sharing options...

Installation\upgrade u-boot on the SD card need to perform on a PC with Linux or on TV box, in the manual using the dd command. Or use a special script, in the parameters which specify the install location (SD card or eMMC). Link to comment Share on other sites More sharing options...

balbes150 Posted December 21, 2017 Share Posted December 21, 2017 1. option. Assemble your own version of a deb package in which to change the script that copies the u-boot. To change the name of /dev/mmcblk0 /dev/mmcblk1 is. 2. option. To start the system from external media and in the manual (using the command dd if=u-boot.bin of=/dev/mmcblk1 is ) to write the desired loader. But I warn you, if you use the wrong u-boot, you will receive a brick that will have to be restored. Link to comment Share on other sites More sharing options...
