Firefly rk3288 : the kernel hangs at "Starting kernel" message

ismael.faye

Hi all,

I am using Firefly rk3288 and I am trying to start it with the kernel linux I have compiled. But it doesn't work correctly. The last message I see is " Starting kernel ..." and few second after the board reboot automatically. Any idea of why it works like that? What the matter? Do I missed something?

I have flashed the kernel respecting the informations given in the link "http://wiki.t-firefly.com/index.php/Firefly-RK3288/Build_kernel/en". But I didn't modify the parameter file... Where is the parameter file located? And what do I have to write in this parameter file in order to run linux kernel in the firefly board?

When I compile the kernel I don't have the "firefly-rk3288.img" as mentionned in the link "http://wiki.t-firefly.com/index.php/Firefly-RK3288/Build_kernel/en". I have kernel.img, boot.img and I flashed this two images using rkflashkit.

I have also compiled the u-boot and flashed it using "sudo upgrade_tool ul RK3288UbootLoader_V2.19.01.bin" command.

After flashing RK3288UbootLoader_V2.19.01.bin, kernel.img and boot.img, the borad doesn't work correctly (See the logs bellow). Have you already faced this kind of problem? How did you managed it? Could you please explain again the differents steps in order to start a kernel linux on firefly rk3288?

the cmdline must contain  ttyS2 and earyprintk instead of ttyFIQ0.

you can find it at FFTools/parameter/

Hi all,

Thank you for your answer.

I have flashed the parameter file in the board and the kernel is going further now. I have the following error message now : "Could not load /lib/modules/3.10.0/modules.dep: No such file or directory" .

The modules.dep file is not found. Any idea of why this error happens? How can we fix it?

In the link "http://wiki.t-firefly.com/index.php/Firefly-RK3288/Build_kernel/en" we have to run the command "rsync -av ./modules_install/ /path/to/your/rfs/lib/modules/". What is the real value of "/path/to/your/rfs/lib/modules/" if we download the kernel source with "git clonehttps://bitbucket.org/T-Firefly/firefly ... -kernel.gi"?

Thank you in advance.

Best regards,

Ismael FAYE

you can try "scp" command to copy  on running firefly

Hizhansb,

I can not run any command on the board due to the error. Do we have another solution?

In the link "http://wiki.t-firefly.com/index.php/Firefly-RK3288/Build_kernel/en" we have to run the command "rsync -av ./modules_install/ /path/to/your/rfs/lib/modules/". What is the real value of "/path/to/your/rfs/lib/modules/" if we download the kernel source with "git clonehttps://bitbucket.org/T-Firefly/firefly ... -kernel.gi"?

Thank you in advance,

>FATAL: Could not load /lib/modules/3.10.0/modules.dep: No such file or directory

modules.dep stores the dependency of the kernel modules.

Since no modules are used in the boot.img, you can safely ignore this.

> rsync -av ./modules_install/ /path/to/your/rfs/lib/modules/

If you have compiled modules, this command will copy all the kernel modules files and their depencency info to /lib/modules to your rfs.

Did you find any solution to this problem?

Experiencing the same issue

liatoss

I have the same problem as at the beginning here - the boot loop... The parameters file doesn't help. Don't know how to fix it, even flashing original files from FireFly doesn't fix the issue.

Any idea how one can fix the loop? This is my original topic for discussion: http://bbs.t-firefly.com/forum.php?mod=viewthread&tid=550

Thx, Vlad.
