How can I check to see which bootloader I already have?

Trial · Jul 25, 2013

Hi,
when you see V2 on VFD at the beginning of boot you have new one.

If the box is on the new bootloader you'll see 'Duo2_CFE_V2' two times in the VFD during the booting.
If you have the original bootloader you won't notice anything.

I get "double your expectation" logo then the other led display comes on. Then booting so must be V1. Will try update and report back. Thanx guys

I only get 'Duo2_CFE_V2' once during booting but i have updated the VFD to V2 does this mean the bootloader still needs updating is there another way to check. If i upgrade the bootloader anyway do i need to reflash Thanks for any help

When you see 'Duo2_CFE_V2' it should be fine.
And indeed: I would reflash the box after the bootloader update. I'm not sure if it's required though.
Make a settings backup and use it for restoring during the First Install Wizard. The box will be up & running again in a couple of minutes.

Make sure to flash with build 723 (and don't update online to 724 as there are some issues).

Thanks Rob will try it now

Why do I need to update the bootloader?

Rob van der Does · Aug 24, 2013

To enable all functionality of your box.

when you say in the instructions "The bootloader only takes a few seconds to flash and once completed you will need to reflash the
receiver making sure to first format the USB stick." do you mean you have to re-install the VIX image?

Larry-G · Nov 26, 2013

yes you should reflash the image once the bootloader has been updated, if the receiver is brand new then it is very unlikely that you will need the bootloader updating as it would have been done in the factory or by your supplier.

tomos · Nov 26, 2013

My box is only about 2 months old, i'll have to check when I get home, I get the message "double your expectation" is that the older version

Larry-G · Nov 26, 2013

I dont have a Duo2 on which to confirm but from information given to me you should see 'Duo2_CFE_V2' on the VFD of the receiver at bootup to signify that it has the V2 bootloader loaded.

tomos · Nov 26, 2013

it won't do any harm if I install the V2 bootloader over what already exists, If I do a full backup before installing V2 can I reinstall the VIX image without using a usb drive?

No it wont do any harm and yes you can backup your existing image first then restore that after the bootloader has been flashed.

tomos · Nov 26, 2013

last question what extra functionality does the latest bootloader give me

Larry-G · Nov 26, 2013

Not sure to be honest but the bootloader controls every thing from the kernel and size of images the box can accept down to the amount of flash available to the end user, these are released by the manufacturer and a recommended upgrade for all users regardless of the image you use.

Hi,
bootloader gives you WOL and I think RC control is a bit better.
