To avoid the installation errors, perform the following steps in the u-boot terminal (gxl_p230_v1#):
1. Copy u-boot.bin and gxl_p230_2g_pie.dtb to the FAT partition of the previously prepared mSD card. Boot the box from the mSD card and execute the following commands:

Code

store disprotect key
store init 3
reset

2. Write the u-boot.bin into the eMMC

Code

fatload mmc 0 ${loadaddr} u-boot.bin
store rom_write ${loadaddr} 0 100000
reset

3. Write the *.dtb file into the eMMC (partitioning)

Code

fatload mmc 0 ${loadaddr} gxl_p230_2g_pie.dtb
store dtb write ${loadaddr}

After these steps you must now be able to boot from the LibreElec SD card.
Insert the LE SD card into the box and execute this command in the u-boot terminal:

Code

run update

or use the RESET button.

I will upload Android IMG a little later...

Code

[store]amlmmc erase 1Cannot find dev.

emmc was not found. Insert the sd card and manually switch to emmc:

Code

mmc dev 1

Now repeat steps 1-3, but without the "reset" command.

There is a little DDR timing problem, I'll try to fix it later.

tried as per instruction provided,

[store]amlmmc not worked for me, was giving error cmd does not exists

tried amlmmc after search on google

02 nos logs attached (tried 2 different attempts)

also attached files present on sd card during the procedure.

(Sd card was prepared with boot card maker, then file pasted on it)

I think my mmc is bad, or need to be replaced...on board...

Code

[mmc_init] mmc init success
switch to partitions #0, OK
mmc1(part 0) is current device

No, everything is fine. I suspect a weak power supply, or something like that..

Code

reading aml_autoscript
** Unable to read file aml_autoscript **

This bootloader needs aml_autoscript so that booting from the SD card works. This script is currently missing on the FAT partition of your SD card. I haven't used an LE for a long time - which files are on your LE SD card?

files available on sd card are already shown in attached image, in the previous post, (sd card is prepared from boot card maker, then files pasted on it.

ie

aml_upgrade_package.img

gxl_p230_2g_pie.dtb

u-boot.bin

do not have any aml_autoscript

Quote from bumerc

Android you can also write to emmc by hand. To do this, you first have to unpack the aml_upgrade_package.img with a repack tool, copy unpacked partitions to the sd card and write to emmc with the following commands:

(First you have to burn the dtb that you already did in step 3), then

Code

sdc_update dtbo dtbo.PARTITION normal
sdc_update boot boot.PARTITION normal
sdc_update recovery recovery.PARTITION normal
sdc_update system system.PARTITION sparse
sdc_update vendor vendor.PARTITION sparse
sdc_update odm odm.PARTITION sparse
sdc_update product product.PARTITION sparse
reboot

"copy unpacked partitions to the sd card"

means copy all unpacked files to sd card root and then
