Hi,

I am trying to boot my OOLITE board using the open source firmware,

I created a ramfs image, it boots upto a point but console gets stuck later with "crng init done " log.

How can i resolve this.?

@ashishsbn1, welcome to the community!

Just hit the Enter key. You device appears booted up.

That usually means the system is completely booted and has enough random numbers for crypto and programmatic use.

Hi IIeachii,

Nothing happens when i hit enter key.

Can you provide any other suggestion. ?

Thanks

Is your device supported?
Provide the link to the ToH page.

It's normal for serial port IRQ sharing to be disabled, especially when there is only one active port.

Like @vgaetera said, the network should be up, try to log in with SSH.

Hi All,

Thanks for your responses,

Now, I am able to boot and get up to login console but as i am using a ramfs/ramdisk image. The changes that i make get lost after reboot. What can i do in order to save the changes that i make in various config file and the local data.

In short, How and where can i define partitioning of the memory.

Thanks
Ashish S

  • Did you flash the device; or are you still booting to RAM?
  • Also, per the Community Guidelines, please refrain from signing your posts.

Hi,

When i flash the device using ramdisk image, it doesn't come up..
Gives same error, Kernel panic

11

Why are you flashing the device with a RAM image?

You should only boot with that image.

12

When i try to flash with squashfs.bin image it gives me same error.

Kernel panic, it says unable to find root=" " boot option

13

Also, i donot see any partitions in dmesg output.

How can i partition memory in my .dts file.
Currently it looks like this:
