Working from the documentation here: https://docs.armbian.com/Developer-Guide_FEL-boot/#what-is-felnfs-boot. Not much luck so far with an FA NanoPi K1 Plus. Please see below for details. TIA.

So this is failing for some odd reason. Armbian command line configuration is:

 

/compile.sh BOARD=nanopik1plus BRANCH=next KERNEL_ONLY=no KERNEL_CONFIGURE=no RELEASE=jessie BUILD_DESKTOP=no ROOTFS_TYPE=fel

 

FEL device mode is activated:

 

@ubuntu-1804:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 005: ID 1f3a:efe8 Onda (unverified) V972 tablet in flashing mode
Bus 002 Device 004: ID 0e0f:0008 VMware, Inc. 

Armbian interaction is then ...

[ o.k. ] Calling image customization script [ customize-image.sh ]
[ o.k. ] Starting FEL boot [ nanopik1plus ]
[ o.k. ] Connect device in FEL mode and press [ <Enter> ]

There is no FEL support for 64-bit targets in the build script.

Hi Zador,

 

Thanks. Have you had any 64bit boards working with NFS?

No.

Root on NFS should not be hard by itself (similar to H3, loading u-boot and kernel from SD).

FEL support, on the other hand, is not implemented in the mainline u-boot for 64-bit chips, so it requires either using prebuilt u-boot binaries or adding patches to u-boot and rewriting the build script.
