Hummingboard Edge - boot problem

ingeniero · January 26, 2016

Hello,

I want to boot Hummingboard Edge with Armbian (Jessie - kernel 3.14.54) , but I'm experiencing problems during the booting procedure.

Bootloader is searching for some files then it gives up. I have copied two files (imx6q-hummingboard2.dtb to imx6q-hummingboard.dtb) to /boot/dtb/ folder. It looks like it starts with the kernel, but it never loads completely. Below are the steps:

I would be happy, if you can give me some pointers on how to solve this problem.

With Solidrun linux port it works normally.

Thank you.

Are you using Armbian patched u-boot?

Hello Igor,

no I use stock u-boot which came with the device. Should it be patched if I want to use Armbian for Hummingboard?

Thank you for your time.

Yes, better.

My u-boot loads boot.scr script and there you can set console output to serial, enlarge debug level to see what's going on, ...

Edit: even this uboot loads script so you need to edit /boot/boot.cmd, set console output and debug level = 7, recompile to boo.scr and reboot.

Hello to everyone,

I am having a similar problem, but with a hummingboard we bought recently. I downloaded the armbian image with ubuntu (server) and we put this image in two hummingboards:

one "I4P" (marked with a sticker on the back) and another one that we recently bought.

On the first one the image works perfectly, but on the second one it stops during boot; We are attaching here a screenshot of the boot sequence. Given that it says it does not find the file "/boot/dtb/imx6-..." we found on the solidrun forum that the different u-boot version would check for dtb files into /boot instead of /boot/dtb/ and so we copied all dtbs into /boot/ but we obtained the same screenshot.

Do you know what would be the issue? Initially we thought that it was a problem of only one of the boards but then we reproduced the problem on all 3 hummingboards we bought.

Best regards and many thanks in advance.
