(SOLVED) Clone emmc from on board to another.

[danielwilson654]

I have setup a custom OS on one Neo Air. I would like to clone that board to create replicas for production. How can this be done?

Thanks!

Thanks! Looks like a good start.

How do you get a NanoPi Neo Air into Fel mode?

I would search the forum but it don't seem to have a search feature and Google didn't show anything helpful.

Hallo,

I still have trouble entering FEL-Mode.

Steps I did:
- created a sd-card with "fel-mass-storage-master/fel-sdboot.img"
-> put it in an untouched NanoPi Neo Air but the pre installed Ubuntu boots

- removed sd-card
- pressed 1 in UART-console while powering on
-> Output:

Code: Select all

eraly jump fel

On my development PC neither "lsusb" nor "sunxi-fel version" (ERROR: Allwinner USB FEL device not found!) find a new device.

The serial-output from http://linux-sunxi.org/FEL looks quit different. One big difference is that im stuck at boot0 but it should "Jump to Boot1.".

Does anyone have an idea of what is going wrong?

Thanks a lot,
