A95X MAX Install

[Sevillano]

Hello to everyone. I'm new in this forum.

I'm trying to install (or adapt to install) armbian in an A95X MAX. I've compiled the entire system on a virtual machine and now i'm trying to boot in the box but no luck, the problem is that I erased the emmc to force the cpu to boot from sd but don´t boot, the only text line i get (via serial console) is "G12A:BL:0253b8:61aa2d;FEAT:F0F831B0:12020;POC:F;RCY:0;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;".

Can anybody help me to decode what this line means? I'm broking the head but whitout result.

Many thanks in advance.

 

Sorry fot my bad english.

@Sevillano I'm not quite sure what steps/instructions you are following.  But start by reading the two TV Box FAQ posts: https://forum.armbian.com/topic/16976-status-of-armbian-on-tv-boxes-please-read-first  and  https://forum.armbian.com/topic/17106-installation-instructions-for-tv-boxes-with-amlogic-cpus

There aren't steps that require you to compile the entire system on a virtual machine.  So I am assuming you are trying to perform a regular build of armbian, but armbian doesn't support TV boxes.  That is why this forum exists and there are the forked builds that attempt to get a working environment on amlogic based boxes.

You will most likely need to find an original android firmware and restore your emmc to a good working android before moving forward.

@Sevillano - as far as i remember the a95x max is one of the rare cases of using a signed/encrypted boot block, so erasing the emmc is not a good idea as you'll not be able to create any boot block with the proper keys to be loaded by the box - reinstallling the original firmware is your only option i guess and then bootiing via legacy u-boot and the regular balbes150 script and maybe chainloaded mainline u-boot

 

good luck and best wishes - hexdump

As far as i know the amlogic boot sequence is (by design)  : when the cpu start it looks for a bootloader in the emmc and if this fail then it looks for in the sd-card. In this thread you can read how it's made (

)

One thing is that for build these bootloaders are necessary some blob's from amlogic that match with your cpu, it's not the same for a S802 than a S905X2 for example. My first goal is try to build the bootloader for the S905X2 (amlogic u211/g12a platform). I've built the mainline u-boot for a board with this cpu and then join with the amlogic blob's but no luck. I keep investigating....

@Sevillano - as said: you may try around more if you like, but i think the only chance you have is to find the original firmware for your box, as it is the only one which was build with the proper keys - this box (and very few others as well - a95xf2, mi-box, ...) is special as the boot process is locked

Thanks. I have the original firmware for my box. I'm decompiling BL2.
